• The color displayed on your Array unit (except AR1 UVC) will inform you of your IAQ. See below for additional details
• 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%.
RESET is a third-party air quality standard. According to RESET, it’s a set of standards and assessment tools & services focused on data quality and data transparency with the purpose of helping built environments become healthier and more sustainable. To learn more about RESET, see this link: https://reset.build/
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.

he air index is a number represented as a percentage to tell you the current IAQ where 100% is considered the best air quality. It’s calculated by measuring total PM2.5, TVOC, and CO2 levels in the air.
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.
On the machine, press the auto button. Alternatively, you can open Array Viewpoint and place the unit into auto 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.
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.
No, there are no sensors in any Array units that can measure carbon monoxide.
  • 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
        • PM2.5 describes fine, inhalable particles with diameters that are generally 2.5 micrometers and smaller. These microscopic solids or liquid droplets can get deep into your lungs and may cause a variety of health issues.
    • PM10 – Particulate 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.
No, the Array sensors are only integrated into the Array units.

Energy Usage & Power

What are the power requirements and how much energy do the units consume

Assuming the unit will run for 12 hours per day, 365 days a year (actual run-time will vary), on an average of the 3rd speed (only 1 speed for AR1 UVC), the estimated annual power consumption for each unit is as follows:

  • AC2 average estimated annual power consumption is 105.12 kWh. Using a $0.16 cost per kWh, the estimated annual cost for power, per unit, is $16.82
  • AR1 average estimated annual power consumption is 52.56 kWh. Using a $0.16 cost per kWh, the estimated annual cost for power, per unit, is $8.41
  • AR2 average estimated annual power consumption is 96.36 kWh. Using a $0.16 cost per kWh, the estimated annual cost for power, per unit, is $15.42
  • AR1 UVC average estimated annual power consumption is 306.6 kWh. Using a $0.16 cost per kWh, the estimated annual cost for power, per unit, is $49.06
  • AW1/AS1 average estimated annual power consumption is 56.94 kWh. Using a $0.16 cost per kWh, the estimated annual cost for power, per unit, is $9.12
  • AW2/AS2 average estimated annual power consumption is 100.74 kWh. Using a $0.16 cost per kWh, the estimated annual cost for power, per unit, is $16.12
Calculation: Watts / 1000 (to convert to kWh) x 12 (12 hours per day) x 365 (365 days) x 0.16 (USA national average cost per kWh) = Estimated annual cost for power per unit per year

*Actual cost of power consumption will vary based on usage and actual cost per kWh.

*Also, the 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.
Our LTE connection will run from 700 MHz to 2.2GHz

Equivalent Air Changes per Hour

  • 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
  • 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.
  • 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.

Connectivity & Viewpoint Dashboard

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.
Updates every 5 minutes
The units upon startup are designed to automatically connect to a cellular LTE connection if possible.
If you have previously connected a unit to the Viewpoint dashboard, it will automatically connect with the same settings once plugged back in.

Product Specific Questions

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