Yes! Our Fellowes AeraMax Pro AM3 & AM4 air purifiers demonstrated, through independent laboratory testing, to be effective in eliminating aerosolized concentration of SARS-CoV-2 by 99.9999% through a single air pass test of the purifier.
In addition, AeraMax Pro air purifiers reached 99.99% airborne reduction of a surrogate Human Coronavirus 229E in a 20m3 test chamber within 1 hour of operation in a separate test.
In addition, AeraMax Pro air purifiers:
Aeramax Pro: 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.
For both Aeramax Pro and Personal units: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 Federal 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.
Note that AeraMax Personal units ship with PlasmaTrue ON; AeraMax Pro units ship with PlasmaTrue OFF. The PlasmaTrue™ feature can be turned off by pressing and holding the icon until the light turns 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.
For AeraMax Personal units: The AeraMax™ DX5/DX55/DX95 Air Purifier does not create harmful ozone. The Environmental Protection Agency has National Ambient Air Quality Standards for pollutants considered harmful to public health and the environment. These standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children and the elderly. The AeraMax™ DX5/DX55/DX95 Air Purifier generates ozone far below the standard set by the EPA. In addition, the AeraMax™ DX5/DX55/DX95 Air Purifier is UL certified, testing well below the UL specification for ozone.

PlasmaTrue™ Technology creates an ionized field to help safely remove airborne pollutants.
For both Aeramax Pro and Personal units:
The PlasmaTrue™ Icon on your indicator screen indicates that the PlasmaTrue™ Technology is active. There is no way for the human eye to see the effect of PlasmaTrue™. Most machines will also produce a bit of a high-pitched noise that comes from the machine when the PlasmaTrue technology is on (not 100% of the time).
Yes, the PlasmaTrue™ Technology feature on the all AeraMax™ Pro and personal Air Purifier units can be turned off by pressing and holding down on the PlasmaTrue™ icon on the touch screen display panel for approximately 5 seconds. The PlasmaTrue™ Technology indicator light will turn off, letting you know that the PlasmaTrue™ Technology feature on the machine is turned off. Please note that if you turn off the PlasmaTrue™ Technology feature, it may reduce the coverage area below the AHAM certified rating.
For both Aeramax Pro and Personal units:
There is no difference between an ionizer and PlasmaTrue™ Technology. Ionizers use electrostatically charged plates to produce positively or negatively charged gas ions that particulate matter sticks to in an effect similar to static electricity. Some ionizers produce Ozone that can be harmful to your health; however, PlasmaTrue™ Technology has been tested and validated per the latest regulation to show that it does not generate harmful Ozone. The Environmental Protection Agency has National Ambient Air Quality Standards for pollutants considered harmful to public health and the environment. These standards provide public health protection, including protecting the health of "sensitive" populations such as asthmatics, children, and the elderly.

For both Aeramax Pro and Personal units:
Wait for a few more minutes. If the lights do not stop blinking, call customer service 1-800-477-7940 for further assistance about the electronics or AeraSmart™ Sensor of your product.
AeraMax™ PRO AM2/AM3/AM4:
Rated Power Watts (NA Units):
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.
Fellowes® AeraMax™ 190/200/DX55/290/300/DX95 Air Purifiers have been tested and certified eco-friendly by Energy Star because they have been designed for a low power consumption and have a lower impact on the environment. In general, products carrying the Energy Star certification consume 20%-30% less energy than what is required by federal standards.
Rated Current (Amps) NA Units:
A True HEPA (High-Efficiency Particulate Absorption) air filter is a filter that removes up to 99.97% of airborne particles as small as 0.3 microns. The Fellowes® AeraMax™ True HEPA Filters are also treated with AeraSafe™ Antimicrobial Treatment that prevents microbes from growing on the filters. The True HEPA filter is the thicker white filter.
A Carbon Filter is a pre-filter that captures the bigger particles to avoid clogging the True HEPA Filter. The Carbon Filter is designed to help remove large airborne particulates and odors from the air. The Carbon Filter is the thinner black filter.
1. Follow guidance of the Filter Change Indicator lights. When the light is lit, you will need to replace the filters. Please see above on how to access the filters.
2. To clean the external housing as necessary wipe with a dry, soft cloth; for stains, use a warm, damp cloth. Do not use volatile fluids such as benzene, paint thinner, or scouring powder, as they may damage the unit surface. Clean intake and exhaust vents by wiping with a dry, soft cloth. For more information regarding maintenance consult the owner's manual.
Fellowes® AeraMax™ Air Purifiers take into consideration the quality of the air they clean, as well as the period of time they are being used, in order to determine the amount of dirt and pollutants that have been captured on the filters. Once this amount has risen to a level where the efficiency of the product is about to start decreasing, the air purifier tells you it's time to replace the filters.
When replacing filters, place the used filter(s) directly into a plastic bag and seal tightly before placing in trash receptacle.
The below videos show how to change filters for the AeraMax Pro 3 and AeraMax Pro 4.
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:
*All figures above vary depending on the cleanliness of your air and how frequently you use your unit.
Please note that the original HEPA filter shipped with the units should be replaced after 12 months.
Aeramax Pro units: 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.
Aeramax Personal units: No, it is essential to only use Fellowes® AeraMax™ filters, as other types of filters will not correctly fit into your product. Other types of filters will leave some air gaps in your product, through which dirty air will be able to pass without being filtered and cleaned. Using other types of filters will dramatically reduce the efficiency of your air purifier.
No. Do not try to clean or wash your filters as you would send all the pollutants they captured back into the air. Simply replace your filters with new ones and dispose of the old, dirty filters.
If your machine has been set up on Auto for several months and if your air has been perfectly clean, it is possible that the filters are still relatively clean when your Filter Indicator Lights tell you to replace them. However, the filters are cleaning particles down to 0.3 microns that are not visible to the human eye, therefore even if the filter looks clean it might contain a fairly large amount of very small particles and pollutants on its surface.
Repeat the Filter Indicator Light Reset Instructions. If it does not resolve the problem, the electronics of the unit might be defective (PCB, software). (Return Product)
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.

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.
Your machine has been designed to accommodate both Fellowes® True HEPA Filter with AeraSafe™ Antimicrobial Treatment and Fellowes® Carbon Filter. Using the machine with only one of those filters would dramatically reduce the efficiency of your air purifier and may result in abnormal air circulation noises, as the space left by the missing filter would allow part of your indoor air to circulate freely without being filtered.
For both Aeramax Pro and Personal units: No, the unit is designed to disable the fan when the filter panel/drawer is opened. Once the filter panel/drawer is re-inserted, the unit will return to the previous state of operation.
Filter replacements are widely sold: check with your current supplier or on www.fellowes.com.
Eventually, the filters will become clogged and the air flow going through the machine will be dramatically reduced, affecting the product's ability to properly clean the air. If there is no air flow through the product and there is an excessive amount of dirt, dust, and pollutants on the filters, the product will not be able to capture the pollutants and keep them on the filters. In this case, the pollutants may be released back into the air.
It protects against the growth of bacteria on the True HEPA filter.
It is on the True HEPA Filter.
No, they are not. Filters are consumable parts that wear under normal conditions.
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 and 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 multiple 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.
For both Aeramax Pro and Personal units: It should not create interferences since the machine is FCC tested and certified. Verify that the interferences are not coming from another appliance or device. To do that, unplug the air purifier and verify if this stops the interferences. If it does, try to use your air purifier further away from the device on which you observe the interferences and on a different power outlet.
All wall mounted AM3/AM4 units need to be hard wired (don't require a dedicated line) while all stand versions (AM3S and AM4S) use a normal plug. Neither can do both (NA - Use AC 120V Only).
All personal units have a power cord (NA - Use AC 120V Only).
For both Aeramax Pro and Personal units: If you are unsure how often to run your unit and at what settings, all our units have an Automatic Mode which will adjust as needed based on your environment. These intelligent sensors automatically adjust unit settings to optimize performance and energy efficiency.
If installing an AeraMax Pro within a circulation path:

Personal Units (AeraMax 100, 90, DX5, DB5, 200, 190, DX55, DB55, 300, 290, DX95) have not been designed to mount on walls.
Aeramax Pro: 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 a smell source (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 AeraSmart™ Sensor. See computational fluid dynamic simulations for further insight.
Aeramax Personal: Units should be placed as close to the source of the contaminant as possible, where contaminated air can be drawn directly into the filtering system. Acceptable places to put you air purifier include, next to a desk, in the corner of a room, etc. 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 a smell source (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 AeraSmart™ Sensor.
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.

Either the AM3 or AM4 can effectively be used depending on the type of room. Restrooms, break areas, and rooms with higher levels of contaminants should utilize the AM4 which provides higher flow rates. Conference rooms, lobby spaces, and other less used, less contaminated areas can be effectively maintained with lower flow rates provided by the AM3.
To estimate the coverage needed divide the hourly air delivery rate of the unit by the total cubic feet of the room. Ideally, you will want to exchange the room's air 5 or more times per hour. For example, the AM3 has an hourly air delivery rate of 13,200 cubic feet (220 cfm x 60), the AM4 is 26,400 (440 cfm x 60).
Yes, your air purifier can clean a bigger room, it will just take more time for it to clean a bigger room than a room for which it is rated. Also, multiple units can be used in the same space to increase square footage coverage.
For both AeraMax Pro and Personal units: Using the machine in a wet area might damage your filter and create a hazard of electric shock if the power cord or any of the electrical components of your product get in contact with water. It is not recommended to use this product in a humid or wet area.
AeraMax™ 190/200/DX55/290/300/DX95 and Pro Units AM2/AM3/AM4: Yes, the air intakes are located on each side of the unit and the air outtake is located on top of the unit, therefore placing the product against the wall won't affect its function.
AeraMax™ 90/100/DX5: It is not recommended to place the unit against a wall, as the air intake is located at the rear of the unit. This model will perform better if it is not placed up against a wall.
In addition, none of the air purifier Units produce heat or anything that could damage a wall surface. It is completely safe to place the products against a wall (except the AeraMax™ 90/100/DX5 which has the air intake located on the rear of the unit).

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.
The EnviroSmart™ sensor technology:
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.
