General FAQ's & RESET Air Index

How is air quality calculated?

At Fellowes, we use RESET Air Standard to monitor the air quality. RESET Air is designed to prioritize on-going results and long-term occupant health with a focus on the operational phase of the built environment.

What is the RESET Air Index?

The RESET Air Standard enables healthier and more productive spaces by defining the RESET Air Index.
The RESET Air Standard requires indoor air quality data to be continuously monitored for the following parameters:

Particulate Matter (PM2.5)
Total Volatile Organic Compounds (TVOC)
Carbon Dioxide (CO2)
Temperature
Relative Humidity

These parameters are then used to calculate the RESET Air Index, which communicates the indoor environment quality as a single percentage.

• How is my RESET Air Index calculated?

Data is collected from all connected sensors
Points are deducted based on levels, recommended thresholds, and parameter weights for PM2.5, TVOC, and CO2.
These deductions are taken from 100% and displayed as the RESET Air Index.

Example:

PM2.5 = 32 ug/m^3 = 9.8 points lost
TVOC = 340 ppb = 0 points lost
CO2 = 450 ppm = 0 points lost
RESET Air Index = 90.2%

To learn more visit www.reset.build

What are the recommendations?

Try to keep it above 80%

What are “Clean” and “Fair”?

Fellowes Air Purifiers are constantly monitoring the RESET Air Index. When the RESET Index is above 80, the units are on low speed and display “Clean”. If the RESET Index ever falls below 80, the units are programmed to automatically increase the fan speed, change display colors, and show “Fair” on the screen.

How do I know if my IAQ is good or bad?

The color displayed on your Array unit (except AR1 UVC) will inform you of your IAQ. See below for additional details.

What does the color changing light (AQI Light) on Array units (except UV) represent?

It represents a band of the air quality standard. Blue (Clean) is above 80%, Yellow (Fair) is 50%-80%, and Red (Poor) is below 50%.
Blinking Blue light indicates an error - to resolve this, double check that filters are seated properly and if needed, power cycle the unit
Purple means the unit is being pinged
White means the filter door is open

Does installing the Array system get your facility RESET certified?

No. Our units may be used to help achieve a RESET certification, but getting your building RESET accredited is a process that your building takes part in with RESET directly.

How do I override EnviroSmart+ Technology?

To turn off EnviroSmart+, simply place the unit into manual mode by clicking the fan speed button. This can be done on the machine or with Array Viewpoint.

How can I tell if the sensors are working?

All units: Log into Array Viewpoint to see live readings
Array Wall/Stand units: See Lookout display on the unit

Do sensors need calibration or other maintenance and how much time should it take my air purifier to calibrate?

The sensors are calibrated at manufacturing, meaning there’s no need for user calibration. For maintenance, keep products clean and dust free. The machine will light up with a green light for the first 60 seconds during calibration.

How do I see current sensor readings?

All units: Open your Array Viewpoint account to see current readings on dashboard
Array Wall/Stand Units: Use the Lookout screen on the units to see current readings
Array Lookout: View readings displayed

How do you adjust fan speed?

When in auto mode, all air purifiers (except AR1 UVC) will automatically adjust fan speed based on air quality. In manual mode, you may choose which speed to set the machine at by pressing the manual mode button until your desired speed is displayed. This can be done on the machine directly or on Array Viewpoint.

How do I go back to auto mode?

On the machine, press the auto button. Alternatively, you can open Array Viewpoint and place the unit into auto mode.

What is the difference between auto mode and quiet mode?

Auto Mode: Allows the machine to adjust fan speed automatically based on sensor information.
Quiet Mode: Adjusts fan speed automatically but reduces the scale, so fan does not go beyond speed 3.

Will the units measure carbon monoxide?

No, there are no sensors in any Array units that can measure carbon monoxide.

Can I upgrade my Gen 1 or Gen 2 AeraMax Pro products to include sensors?

No, the Array sensors are only integrated into the Array units.

What is Energy Star and what are the requirements for a product to be certified?

ENERGY STAR® is the government-backed symbol for energy efficiency. Energy Star requirements for air purifiers are as follows from energystar.gov: To certify for Energy Star, the Rated Smoke CADR divided by the operating power consumption measured during the smoke particle removal test (equal to Smoke CADR / Watt) shall be greater than or equal to the Minimum Smoke CADR/Watt Requirement.
The current Department of Energy (DoE) conservation standard and the subsequent "Energy Star” certification only apply to residential units as they both use AHAM standards which are clearly specified for residential application.
Many of our units are explicitly excluded from the DOE conservation standards, as AHAM standards explicitly exclude products that are:
- Installed in the ceiling
- Capable of greater than 600 CFM
- Hard-wired and not corded

What sensors are in Array products and what are their specifications (EnviroSmart+)?

Monitoring and comfort sensors
- Motion
  - The motion sensor is used to detect the presence of a person within the immediate area of the unit. It detects relative movement between zones, and we communicate that data to determine whether a room is occupied or not. The more movement detected, the more likely a room is occupied.
- Sound
  - The audio sensor converts sound into electrical signals, which then communicates whether a room is occupied or not.
- Light
  - The light sensor gives an analog signal based on the brightness of the room. We use the amount of light present in the room to determine the brightness of the AQI light.
- Pressure
  - Air always flows from high pressure to low pressure. Facilities want to maintain a slightly positive pressure relative to outdoor air pressure to help assure outdoor pollutants don’t enter the building. Facilities managers find this useful for balancing HVAC system
  - The pressure sensor translates the air pressure of the space into an electrical signal to monitor comfort and ensure optimal functionality of the rest of the sensor suite.
RESET Air Class B IAQ Sensors
- PM2.5/PM10
  - This sensor uses laser diffraction to measure the amount of particulate in the air. This value is used to determine the machine’s fan speed.
  - PM2.5 - Particulate matter at 2.5 micrometers in size
- PM10 - Paticulate matter at 10 micrometers in size
  - Outdoor sources include engine exhaust, dust, wildfires/waste burning, industrial sources, pollen and fragments of bacteria. Indoor, 3D printers, business machines, cooking appliances
  - The increase of outdoor PM10 concentration significantly affects the increase of indoor PM10
TVOC - Total volatile organic compounds
- Volatile organic compounds (VOCs) are emitted as gases from certain solids or liquids. VOCs include a variety of chemicals, some of which may have short- and long-term adverse health effects. Sources include cleaning agents, air fresheners, pesticides. Off-gassing from new furniture, construction materials.
- The VOC/TVOC sensor is used to determine the relative air quality around the sensor. It gives off an electrical signal proportional to the amount of volatile organic compounds in the air. This signal is used to determine the machine’s fan speed.
Temp
- Temperature and relative humidity are shown to impact the airborne transmission of human pathogens. Higher temperature with lower humidity levels allows particulate to stay suspended longer, potentially increasing airborne infection.
- The most basic indication of indoor air quality is its temperature: you immediately sense if it’s ‘too hot’ or ‘too cold’. And it immediately affects your sense of well-being.
- The Temperature sensor is used to align with the RESET air index requirements. This is monitored because temperature effects the function of the other sensors.
RH - Relative Humidity
- Relative humidity is the amount of water vapor in the air. Humidity levels impact sense of well-being, can have an impact on the transmission of airborne pathogens, as well as the built environment.
- The relative humidity sensor is used to align with the RESET air index requirements. This is monitored because relative humidity effects the function of the other sensors
CO2 - Carbon Dioxide
- Carbon dioxide is a colorless, odorless gas produced in indoor environments by people breathing. High levels of CO2 can be an indication of poor HVAC performance. Further, CO2 monitoring may be used to assess the risk of indoor airborne respiratory disease transmission.
- The Carbon Dioxide sensor is used to determine room occupancy, as well as align with the RESET air index requirements.

What is the LTE frequency (hertz) for the Array units?

Our LTE connection will run from 700 MHz to 2.2GHz

Are Fellowes Array units energy efficient?

Yes, Fellowes Array units are "intelligent" in that they use sensors to self-regulate their settings based on the room's occupancy and condition (excluding AR1 UVC). This helps optimize air cleaning performance and energy efficiency.

Equivalent Air Changes per Hour

What is the ACH Rating?

ACH stands for “Air Changes per Hour” and is one of the least understood ratings on air purifiers. The ACH rating indicates how many times per hour an air purifying device can exchange the air within a room. For example, an ACH rating of 5x means that the full air volume is exchanged five times every hour.
All air purifiers display a Cubic Feet per Minute (CFM) number under the specifications. If you multiply the CFM by 60 (minutes per hour) and divide by 8 feet (average ceiling height). Then divide that total by the ACH rating, you’ll end up with the maximum square footage number for the air purifier.
Air changes per hour, or air change rate, abbreviated ACH or ACPH, is a measure of the air volume added to or removed from a space (normally a room or house) divided by the volume of the space. If the air in the space is either uniform or perfectly mixed, air changes per hour is a measure of how many times the air within a defined space is replaced.
To estimate the coverage needed, divide the hourly air delivery rate of the unit by the total cubic feet of the room. The CDC recommends 5 air changes per hour.

Is my HVAC system enough to purify the air?

Generally, HVAC does not run continuously in all spaces. HVAC systems stop when the room reaches thermostat temperature, since they’re designed to be efficient at heating/cooling. Only 10-20% of fresh air makes it into the building, while 80-90% is recirculated air. Additionally, a standard MERV-13 filter found in HVAC systems provide insufficient capture rates: 50% effective at .3 microns (according to ASHRAE) vs Fellowes’ H13 True HEPA filters which capture at least 99.95% of particles as small as 0.1 microns. CDC, ASHRAE, and the White House all recommend adding a HEPA air purifier where HVAC is unable to meet air quality needs.

What is a MERV rating and what rating would a Fellowes HEPA filter be?

According to the EPA, Minimum Efficiency Reporting Value, or MERV, reports a filter's ability to capture larger particles between 0.3 and 10 microns (µm). This value is helpful in comparing the performance of different filters. The rating is derived from a test method developed by the American Society of Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) [see www.ashrae.org]. The higher the MERV rating the better the filter is at trapping specific types of particles. Most HEPA filters would be considered a MERV 17 or above, depending on filter effectiveness, The MERV rating of Fellowes H13 True HEPA Hybrid filter would be MERV 18 or above, as it captures up to 99.95% of particles as small as 0.1 microns including allergens, pollen, dust, pet dander and smoke.

Why is In-Room Air Purification + HVAC more efficient than HVAC “upgrades” alone?

Studies show that the addition of an in-room air purification system does increase energy consumption over an HVAC's standard operation. However, it is less expensive when compared to increasing the HVAC's filter efficiency (MERV 8 to MERV 13), bringing in more outside air, and running the HVAC system longer than normal These are all required for proper mitigation of airborne pathogens using an HVAC system only.
- Increase in filter capture efficiency causes an increase in energy consumption due to pressure drop (more resistance)
- Increasing the volume of outdoor air requires an increase in heating and/or colling costs
- HVAC systems can't mitigate airborne pathogens if not running, therefore longer run time - and often at higher rates - is required resulting in an increase in energy consumption.

Connectivity & Viewpoint Dashboard

Why does the system use LTE? Isn’t Wi-Fi easier?

It uses LTE because it doesn’t require any system specific information. Unlike Wi-Fi, all that’s required is product information, it is faster and doesn’t require internal system IT permissions.

How often is data updated on Array Viewpoint?

Updates every 5 minutes

How do I connect my unit to the internet?

The units upon startup are designed to automatically connect to a cellular LTE connection if possible.

If I unplug any of the units, including Array Signal, will the units automatically connect to Array Viewpoint once they’re plugged back in?

If you have previously connected a unit to the Viewpoint dashboard, it will automatically connect with the same settings once plugged back in.

Is Fellowes Viewpoint AIT Section 508 Compliant?

According to Section E202.5 that applies to Information and Communication Technology (ICT) functions located in maintenance or monitoring spaces exception, Fellowes Viewpoint is an exception to the 508 Standard for the following reason: Viewpoint includes status indicators and is typically located in spaces that are frequented only by service personnel for maintenance, repair, or occasional monitoring of equipment. Refer to https://www.section508.gov/buy/determine-508-standards-exceptions/ for additional details.

Is there a fee for LTE?

Every unit independently and securely connects to the cloud utilizing LTE which means that you won't need to have a local network in order to use our technology. There is an annual fee of $20 per Array unit for LTE. These fees can be waived with the purchase of a Viewpoint Plus Subscription or participation in our Filter Reminder Service which requires you to buy or replace filters for your Array units as scheduled. See Fellowes Array Viewpoint Terms & Conditions for additional details.

What is the Array IoT Security Protocol?

Our IoT security protocols are designed to mitigate risks and safeguard sensitive data across various trust factors including privacy, security, availability, processing integrity, and confidentiality.

Array BMS Integration

What is a Building Management System (BMS):

Focus: Provides a centralized platform to monitor and control all major building systems.
Functionality: Integrates various systems (HVAC, lighting, fire safety, security) into one interface, offering comprehensive management and advanced analytics.

The main goals of a BMS are to keep the building comfortable, save energy, and ensure everything runs smoothly.
By doing this, it helps reduce costs and improve the overall efficiency of the building.

Example: Tracking energy usage across different floors, identifying HVAC faults, or monitoring security footage from a single dashboard.

How Does Fellowes integrate with a BMS?

Our air purifiers and monitors would feed data to the BMS
The BMS would act upon the data it received by controlling systems like the HVAC, or potentially air purifiers

Where can I find the PICs documents for Array units?

Purpose: It facilitates the exchange of information between various building systems such as HVAC (heating, ventilation, and air conditioning), lighting, access control, and fire detection systems
Standards: BACnet is standardized by ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers), ANSI (American National Standards Institute), and ISO (International Organization for Standardization)
Interoperability: One of its main advantages is interoperability, allowing devices from different manufacturers to communicate and work together seamlessly
Open Protocol: It is an open protocol, meaning it does not require any licensing fees for implementation, making it widely adopted across the industry

Product Specific Questions

Is there a concern of hinge overextension on an Array Recess unit if the door is released without anyone holding on?

No, even if the Recess door is released without anyone holding on, there shouldn’t be a concern of overextending the hinges.

Array Signal:

What is the total coverage of a single Array Signal?

Total coverage of an Array Signal is heavily determined by a building’s airflow as well as the presence of physical barriers. For example, a space with adequate airflow (4-6 ACH) can be measured by one Array Signal (up to 5,382 sq ft) as long as it’s placed in the “breathing zone” (above 3’ and below 6’) and not obstructed with any physical barriers. Note: If your building is seeking a RESET certification, click here for specific requirements regarding sensor placement and monitoring requirements.

Where does Array Signal collect air from?

It draws air from one side on top.

How do you clean an Array Signal?

If there is dust accumulating, try wiping it off with a damp cloth, or you can vacuum out dust.

Optimal Placement

To ensure the best signal strength, we strongly recommend that you avoid installing Array Signal on or near the following: large metal objects, electrical equipment, sources of extreme moisture, metal stud framing, and corners.

How long is the sensor life in a Signal?

Our current main sensors (PM, CO2, TVOC) have 10 or more years of life. The others (Motion, Light, Sound, Temp, RH, Pressure) have 9 or more years of life.

Array Lookout:

How often does the data update on Array Lookout?

Data is updated every 5 minutes

Does the Array Lookout have sensors in it?

No, the data displayed on the Lookout is an aggregate of the air purifiers connected to it.

Will the data displayed on an Array Lookout be for all units in a facility or only the unit/units in the same room?

Customizable based on setup, but usually will display data within the same room and/or Array units assigned to an Area by the Viewpoint administrator.

Can you use a Lookout to display whole building IAQ?

No, Lookout will display an aggregate of the IAQ in its assigned area but won’t show entire building IAQ.

Does the Lookout display room temperature?

Which account do you need to log into Array Lookout?

To log in to Array Lookout, you need to have either an Admin or Maintenance account in Array Viewpoint. A “View Only” account will not be able to log in to Array Lookout

Is there a concern of fan speed degradation on UVC?

If the pre-filter doesn’t become overly clogged with larger particles, there shouldn’t be a concern of fan speed degradation. We recommend following the regularly scheduled filter change cadence as communicated by the unit.

How do I access the unit’s filters and how do I change them?

Follow filter change instructions in your item’s manual

How often do the filters need to be replaced?

The 3-in-1 filter in AC2, AR1, and AR2 has a 1-year filter life.
The hybrid filter in the AS1, AS2, AW1, and AW2 has a 1-year filter life other than the separate pre-filter, which has a filter life of 6-12 months.
The AR1 UVC bulb has a lifespan of 9000 hours, or about 1 year. The prefilter has a filter life of 6-12 months.

How do I turn off the external LED red light and red Filter Indicator Lights? (Filter Indicator Light Reset)

The red light indicates that filter life has reached 100%.
Press each filter button individually for 2 seconds to reset the life counter of the filter (for units with two sets of filters; L button is for left side and R button is for right side)
For more detailed steps, check your item’s manual

Can I wash/clean my existing filters and reuse?

No, all filters used in Array machines are single-use and not washable.

Will the filter/s fall out of an Array Recess AR1/AR2 if its unlocked?

We recommend the user hold the filter while unlocking.

What is the shelf life of the filters?

To maximize your filter’s shelf life, store in a cool dry place.

Why are the CFM numbers on the Array Wall/Stand units different than AeraMax Pro?

The Array Wall/Stand units come standard with Hybrid filters, while AeraMax Pro units come standard with a 2” HEPA and 3/8” Carbon filter instead. A Hybrid filter composition is different than the other option, so air moves differently through each filter configuration. Both are equally as effective, just made slightly differently.

Does the On-Unit Lookout tell me when the filter is out?

Yes

Can I use another brand of filter, or private label filters in a Fellowes Air Purifier?

These products were designed and certified to only be compatible with Fellowes branded filters. Damage or performance issues caused by use of non-Fellowes approved filters or failure to follow the recommended replacement schedule will void the warranty.

Fellowes UVC Technology

What is UV?

According to the FDA, all radiation is a form of energy, most of which is invisible to the human eye. UV radiation is only one form of radiation, and it is measured on a scientific scale called the electromagnetic (EM) spectrum.
UV radiation is only one type of EM energy you may be familiar with. Radio waves that transmit sound from a radio station’s tower to your stereo, or between cell phones; microwaves, like those that heat your food in a microwave oven; visible light that is emitted from the lights in your home; and X-rays like those used in hospital X-ray machines to capture images of the bones inside your body, are all forms of EM energy.
UV radiation is the portion of the EM spectrum between X-rays and visible light.

What are the different UV types? (All following information is according to the FDA)

The most common form of UV radiation is sunlight, which produces three main types of UV rays: UVA, UVB, UVC.
UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer.
UVA – Ultraviolet A enhances the harmful effects of ultraviolet B radiation and is also responsible for some photosensitivity reactions; it is used therapeutically in the treatment of a variety of skin disorders.
UVB – Ultraviolet B causes sunburn and several damaging photochemical changes within cells, including damage to DNA, leading to premature aging of the skin, premalignant and malignant changes, and a variety of photosensitivity reactions; it is also used therapeutically for treatment of skin disorders.
UVC – Ultraviolet C radiation is the highest energy portion of the UV radiation spectrum. UVC radiation from the sun does not reach the earth’s surface because it is blocked by the ozone layer in the atmosphere. Thus, the only way that humans can be exposed to UVC radiation is from an artificial source like a lamp or laser

Explain our UVC and why we chose this

According to the FDA, UVC radiation is a known disinfectant for air, water, and nonporous surfaces. UVC radiation has effectively been used for decades to reduce the spread of bacteria, such as tuberculosis. For this reason, UVC lamps are often called “germicidal” lamps. UVC radiation has been shown to destroy the outer protein coating of the SARS-Coronavirus. UVB and UVA radiation is expected to be less effective than UVC radiation at inactivating the SARS-CoV-2 coronavirus.
There is some evidence that UVB radiation is effective at inactivating other SARS viruses (not SARS-CoV-2). However, it is less effective than UVC at doing so and is more hazardous to humans than UVC radiation because UVB radiation can penetrate deeper into the skin and eye. UVB is known to cause DNA damage and is a risk factor in developing skin cancer and cataracts.
UVA radiation is less hazardous than UVB radiation but is also significantly (approximately 1000 times) less effective than either UVB or UVC radiation at inactivating other SARS viruses. UVA is also implicated in skin aging and risk of skin cancer.
According to the EPA, given sufficient exposure time and lamp power, UV light can penetrate the outer structure of a microorganism’s cell(s) and alter its DNA, preventing replication and causing cell death.

Why did Fellowes decide to develop a standalone UV-C Unit?

Fellowes has focused design/engineering for air purifiers around “capturing” particulate and bacteria/viruses. But for these devices and their capabilities, it ends there.
What we were missing was the elimination of pathogens. Adding a UV bulb to our existing air purifiers doesn’t solve that problem due to the high air speed not allowing the proper dwell time for a first pass kill rate, so we developed a UV only machine to efficiently eliminate pathogens, in one pass.
Also, Combo HEPA/UV units and or any plastic bodied units with UV bulbs, the UV will deteriorate the plastic and therefore the unit over time.
AR1 UVC device is a complement to our Air Purifier line where a customer can choose to outfit their space with air cleaners that capture pathogens, and now eliminate them should they choose to want that capability.

What defines “UVC done right” for the Array AR1 UVC?

Proper dwell time – not possible in combo HEPA/UV units. They are inversely proportional. Either effective HEPA and ineffective UV, or vice versa
- Lower CFM for UV-only unit
  - UV needs slow air (dwell time)
- Optimized laminar airflow design maximizes CFM while maintaining control over dwell time.
- Large UV chamber
- Not HEPA/UV Combo
  - HEPA needs fast air (CFM)
  - Not paying for UV that “kills” what is already trapped on the filter and removed from the air by HEPA
Kill claim – bolstered by high first pass kill rate
- Ultra-high reflectivity chamber maximizes UV effectiveness within chamber
- Not relying on multiple passes at high airflow for cleaning efficiency
Our unit’s ultra-high reflectivity chamber utilizes a shielded all metal chamber…designed to last for the life of the unit.
- The high-performance air flow chamber with UV safe shielding is proprietary and Patent Pending
- No external or leaking UV light allows for safe use in close proximity in occupied spaces

What is the best application for the Recess UV (any particular space or circumstance)?

In applications where facilities seek to kill instead of capture, such as a hospital room, classroom, daycare centers, assisted living spaces

Is UVC harmful?

No, UVC technology is commonly used and is safe and effective at cleaning air in a room when designed correctly.

Some products have HEPA and UVC combined, why don’t Fellowes air purifiers have both in one machine?

They clean in two separate ways. Ideal HEPA units need high air flow. Ideal UVC units need increased dwell time which decreases airflow.

Why doesn’t the AR1 UVC have sensors?

It doesn’t have sensors since its designed to run continuously at only one fan speed.

Why does AR1 UVC only have one fan speed?

This is the highest fan speed that the machine can operate at before its cleaning effectiveness is impacted.

What is the difference between a kill claim and a capture claim?

HEPA filters capture particles while UVC kills particles. Certain spaces seek to capture a variety of particles while other spaces seek to kill them.

What is the UVC Bulb disposal process?

EPA recommends that consumers take advantage of available local options for recycling CFLs, fluorescent bulbs and other bulbs that contain mercury, and all other hazardous wastes, rather than disposing of them in regular trash.
Your area may prohibit disposal and/or require recycling. Some states and local jurisdictions have more stringent regulations than U.S. EPA does and may require that you recycle CFLs and other mercury-containing light bulbs. Visit search.Earth911.com to contact your local waste collection agency, which can tell you if such a requirement exists in your state or locality. The EPA are aware that the following states prohibit mercury-containing lamps from being discarded into landfills:
- California
- Maine
- Massachusetts
- New Hampshire
- Vermont
- Washington
*Note: The UVC bulb is not “recyclable”

Can you use alternative bulbs and not Fellowes’ UVC Bulb?

No, we only recommend using Fellowes’ UVC Bulb. Using alternative bulbs might not function or work the same as ours. Also, using 3rd party bulbs will void performance characteristics.

Does the UV bulb have a coating on it?

No, the UVC bulb we recommend using does not have a “coating” on it.

Installation, Mounting, & Optimal Air Flow

What’re the recommended installation positions to assure ADA compliance for protruding objects?

Array Signal/Lookout can be mounted anywhere on a wall, and it will be compliant with ADA.

What is the optimal height to hang Array Ceiling over a space?

The Array Ceiling can be mounted in ceilings as high as 20’. Ideally, we recommend units be at least 8’ from the ground as this place’s units above the breathing zone, as well as meet ADA requirements. The Array Ceiling is also recommended to hang at least 12 inches from the ceiling.

Where is the optimal placement of an Array Wall/Stand unit?

Units should be installed as close to the source of the contaminant as possible, where contaminated air can be drawn directly into the filtering system. Also, by placing the unit higher on the wall, close to the ceiling (always allow a minimum of 8” space from ceiling and top of unit) the unit’s powerful exhaust can circulate purified air throughout the room. The best places have 1-2 feet of free space around the product to allow for air circulation. It is NOT recommended to put your air purifier close to direct heat, a vent, or things such as next to an air conditioner, a fireplace, a fan, etc. The direct proximity of those could have an influence on the correct functioning of your unit’s EnviroSmart+™ sensors.

Can you install an Array Recess unit in a drywall ceiling?

The unit will function in a drywall ceiling, but we currently do not have a complete aesthetic kit for mounting a recess unit into a drywall ceiling.

Where does the dirty air enter and exit my air purifier?

Enter:
- Ceiling
  - Top and bottom
- Recess, Wall, Stand
  - Bottom
Exit:
- Ceiling
  - Sides
- Recess
  - Bottom
- Wall/Stand
  - Top

Where should Array Signal be placed and is there a height limit?

The ideal placement of the Array Signal would be in the “breathing zone” which is above 3’ and below 6’. Array Signal will be most effective when its placed as close to the source of the contaminant as possible. If your building is seeking a RESET certification, please see RESET requirements for proper placement. Placing an Array Signal as close to the center of a room will maximize the area that it will sense. Note: Do not place Signal on a metallic surface, as it can interfere with the Signal’s antenna or signal strength.

Can an Array Signal be mounted to a ceiling?

It is not recommended that the Signal be mounted to a ceiling, as the Signal’s optimal placement should be in the “breathing zone”. However, technically, the Signal can be mounted to a ceiling if there are no flat surfaces to place the unit on. Note: Array Signal was never considered to be mounted in that orientation, therefore it hasn’t been tested in that orientation. With that in mind, if the Signal does come online after being mounted to a ceiling, the readings may vary slightly. Hot air rises, in which case, temperature readings may be a bit higher. Most but not all VOCs are heavier than air and therefore will fall to the ground and may not reach the sensors in the Signal if it’s mounted to the ceiling - in which case you’ll get lower VOC readings.

What does installing an Array product cost?

This will vary by project. All Array units require a professional electrician to wire the units other than the Array Stand AS1 and AS2.

Can you use a Floor-to-Wall kit on Array Stand AS1 and AS2?

Yes, if you’d like to convert your AS1/AS2 to a wall mountable unit with a plug, you may use the appropriate Floor-to-Wall kit in order to achieve this.

What is the minimum ceiling plenum height required in order to install an Array Recess unit?AS2?

At a minimum, you will need at least the height of the unit plus the mounting hardware above it to fit into the plenum, so that the unit does not rest on the grid or dip below it.

What should you consider when mounting an Array Signal?

To ensure the best signal strength, we strongly recommend that you avoid installing Array Signal on or near the following: large metal objects, electrical equipment, sources of extreme moisture, metal stud framing, and corners.

How can you mount Array Relay?

Align Relay with the bracket’s mounting holes.
Secure Relay using two flat head screws (screws included).
Align Relay with the rack’s mounting slots or against desired wall location.
Use appropriate screws to attach the bracket to the rack or wall.
Plug the power connector into the DC IN port on Relay.
Twist the connector clockwise until it locks securely into place.
Plug the other end of the power connector into a standard electrical outlet.
Check the Power LED— a green light indicates the Relay is powered on.

Why Purify with Array

Why is Fellowes Air Purifiers better suited for shared spaces compared to other purifiers?

Fellowes Array products are better suited since we can measure, monitor, and mitigate all at the same time. Our four pillars define our products:
- Seamless & Scalable Integration
- Automatic Sense & React Technology
- Effective & Efficient Filtration
- Monitoring & Real-time Data

Are there any other competitors or like items in the market?

Currently, there are no competitors that offer a complete line of products like we do. They might contain certain components but lack the end-to-end solution that we provide.

Would an Array HEPA unit work in tandem with an AR1 UVC unit?

Yes, an Array HEPA unit and an AR1 UVC unit can be placed within the same space so they can leverage each other’s strengths.

Airborne Contaminants

How effective are Array HEPA units?

Our H13 True HEPA air purifiers are 99.95% effective in capturing molecules as small as 0.1 microns including viruses, allergens, and germs.

Can Array HEPA units capture SARS-Cov-2 (the virus that causes COVID-19)?

For Array AF1 filter, testing is in-progress
For Array Wall/Stand units, the Hybrid filter has been tested to be effective at capturing SARS-Cov-2

What else can Array HEPA units capture?

For Array AF1 filter, the 3-in-1 filter has been tested to be effective at capturing H1N1 and Rhinovirus
For Array Wall/Stand units, the Hybrid filter has been tested to be effective at capturing H1N1 and Rhinovirus

How effective is the AR1 UVC?

98.1% Single Pass Kill Rate. Based on 98.1% Single Pass Reduction in Staphylococcus epidermidis bacteria and 87.7% Single Pass Reduction in Bacteriophage Phi6 virus which is a surrogate for coronaviruses (including SARS-CoV-2). The term “Kill” is used to represent the inactivation of pathogens from the UV-C light.

For the AR1 UVC, can it also capture contaminants such as SARS-CoV-2 or H1N1?

UVC technology is designed to kill the contaminants, not capture. The AR1 UVC has a first pass kill rate of 98.1%. This means that 98.1% of all contaminants passing through the AR1 UVC will be killed on their first pass through the machine.
