Fellowes AeraMax Pro air purifiers were demonstrated through independent laboratory testing to be effective in reducing aerosolized airborne concentration of Human Coronavirus 229E in a test chamber, reaching 99.99% airborne reduction within 1 hour of operation.
At the time of writing (April 2021), it is not yet possible or ethically responsible for labs to aerosolize live Sars-CoV-2 (the virus that causes COVID-19) for airborne testing in large (adequately sized) test chamber. We are aware of some claims from other manufacturers using extremely small test chambers (<15 cu ft.) but the test chamber used for our Coronavirus 229E testing was 20m3 (over 700 cu. Ft.) which is more representative of air movement in a real-world environment.
Single-strand RNA envelope viruses such as Coronavirus 229E are often used and accepted as a surrogate for SARS-CoV-2 to study antiviral effect of a specific device.
IIn addition, AeraMax Pro air purifiers:
Both the AM3 and AM4 have 4 settings. The sound levels (dB) vary at each setting. For the AM3 the levels are 39, 46, 51 and 64. The AM4 sound levels (dB) are 49, 56, 61 and 74.
As a reference, many hand dryers sound pressure levels exceed 100 (dB), with averages around 80+ (dB). AeraMax Pro can be set to "quiet mode" and will run at or below the ambient sound level of the room in which it is installed.
The PlasmaTrue™ bipolar ionizer produces clusters of positive and negative (bipolar) ions. These charged ions are dispersed into the air, and electrically charge airborne particles so that they attach to nearby surfaces and to one another, and settle faster. Charging and clustering airborne particles, enhances removal by filtration. Also, the ions react with oxygen and water vapor present in the air to create free radicals. The free radicals, in turn, can create chemical changes.
For example, they damage microorganisms (e.g., bacteria, viruses, and molds) and break down odors and VOCs.

Air purifiers, like many other products (computers, monitors, copiers, ceiling fans, and more) have a normal "ozone byproduct." An acceptable level for ozone byproduct has been set in the Code of Fedral Regulations (CFR) at a maximum 50 parts per billion (ppb). All air purifying devices must pass Underwriter Laboratories (UL) 867*.
In July 2013, Underwriter Laboratories conducted UL 867 testing procedures to determine the level of ozone byproduct generation by the PlasmaTRUE™ bipolar ionizer used in AeraMax Pro purifiers. The highest level of ozone generation observed during testing was 4.0 ppb (acceptable level for ozone is up to 50.0 ppb).
For reference, the Environmental Protection Agency developed the Air Quality Index for Ozone to give guidance to state and local air quality forecasters to assist in issuing Air Quality Index forecasts. The levels are:
Cities like Houston, TX and Los Angeles, CA can have indexes of 80 to 100 ppb at different times of the year.
The PlasmaTRUE™ feature can be turned off.
* This standard for acceptable levels of ozone byproduct is found in section 21:801.415 of the Code of Federal Regulations (CFR) and Underwriters Laboratory (UL) standard 867.
The EnviroSmart™ sensor technology:

Assuming the systems will run for 10 hours per day, 365 days a year (it is likely actual run-time will be less), the estimated annual power consumption for each unit is as follows:
Also, the units are “intelligent” in that they use sensors to self-regulate their settings based on the room’s occupancy and condition. This helps optimize air cleaning performance and energy efficiency.

The replacement filter indicators will signal when to replace the HEPA filter(s) and/or carbon filter(s). The replacement period will vary depending on the hours of use and air quality. However, under normal operating conditions, filter life is estimated to be the following:
Please note that the original HEPA filter shipped with the units should be replaced after 12 months.
No, the EnviroSmart™ sensor technology in an AeraMax Pro takes into consideration the type of filters loaded into the unit to optimize performance. Only certified AeraMax Pro filters can be read by the sensor technology. The unit will not run if its sensors do not detect the information located in certified AeraMax Pro filters.
Absorption is the process in which a fluid is dissolved by a liquid or a solid (absorbent). Adsorption is the process in which atoms, ions or molecules from a substance (gas, liquid or dissolved solid) adhere to a surface of the adsorbent. When using “absorb,” one can say that something moves inside an object. But in the case of “adsorb,” something forms a layer on the surface of an object.
Activated carbon filters adsorb odor and volatile organic compounds.
When replacing filters, place the used filter(s) directly into a plastic bag and seal tightly before placing in trash receptacle.
AeraMax Pro is designed to complement HVAC systems by filtering air at the source of the contaminant. Also, most HVAC systems do not utilize HEPA filtration, which captures airborne contaminants as small as 0.3 microns including viruses, bacteria, and other airborne contaminants. HVAC systems may not have activated carbon filters to remove odor and volatile organic compounds, or bipolar ionizers to reduce airborne contaminants.
Systems have intelligent sensors that automatically adjust unit settings to optimize performance and energy efficiency. You can simply select from two primary modes and the units will monitor themselves:
Override settings are also available. Please consult your owner’s manual for further information.
If installing an AeraMax Pro within a circulation path:

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 up near the ceiling (always allow 8” space from ceiling and top of unit) the unit’s powerful exhaust can circulate purified air throughout the room. See computational fluid dynamic simulations for further insight.
Any device that creates a strong air flow, such as an air conditioner, hand dryer, fan and HVAC system, can alter the projection of the purified air coming from the unit, as well as air being drawn into the system. Air flow can also be altered by cubicles, partitions, stalls, furnishings, half-walls, and other physical barriers and should all be considered when determining an installation location.
AeraMax Pro has patented sensor technology that automatically adjusts the unit based on conditions in the room to optimize purification and energy efficiency. No monitoring by staff is required.
Systems also have a vandal resistant design. Controls and filters cannot be accessed without unlocking the unit. The purifier filters, housing, motor, and balanced fan are all commercial-grade to hold up to the rigors of public and shared spaces.
No. However, Fellowes is pursuing multiple means of demonstrating the efficacy of AeraMax Pro. Laboratory and clinical studies are options being explored.
Even the cleanest facilities can have multiple areas that are sources of constant contamination. Anywhere that people gather, airborne contaminants can be generated—and, unfortunately, shared. These areas include restrooms, classrooms, waiting areas, ambulatory care, day care and nursery facilities, cafeterias/break-rooms, common rooms, and crowded office cubicle areas.
Many of these areas, such as restrooms and cafeterias, can also be constant sources of odor.
While the activated carbon filter in the unit can adsorb numerous gases, air quality control systems are not designed for, or intended for use in, mitigation of radon in a facility. Contact a radon mitigation specialist. National Radon Proficiency Program (NRPP) maintains lists of certified radon contractors, radon measurement service providers, and analytical laboratories.
Not with the source of the mold. Consult a mold remediator. For more information, contact The National Association of Mold Remediators and Inspectors. However, AeraMax Professional utilizes a high efficiency particulate air (HEPA) filter, which captures airborne germs and allergens including mold spores that are drawn into the system.
