Being a tower air cleaner, Fellowes Aeramax 100 /DX5 comes with a modest air cleaning output that is suitable for all types of room. At max speed, it can cover up to 100 square feet of space with decent air changes per hour. For small spaces, you can adjust the 3 fan speed to get a balance between the air performance and noise level.

In auto mode, the air cleaner will automatically set to higher fan speed when high airborne pollutants are detected and revert back to low when the air is clean. No sleep mode is available due to the lack of a light sensor.

What’s inside count

Despite having a smaller tower body, Fellowes AeraMax100/ DX5 is fitted with a conventional 4-Stage purification system. The first stage charcoal pre-filter traps large contaminants like dust, hair, lint while also remove smoke, toxic fumes, and smelly odor. Next, the True HEPA filter captures 9.97% of fine particles as small as 0.3 microns i.e. mold, pollen, pet dander, bacteria, and viruses. The HEPA filter is also coated with AeraSafe antimicrobial treatment that prevents microorganisms' growth on the filter. Finally, the PlasmaTrue ionizer can generate an ionized field that merges positive ions. The diffuse ions will merge and pull positive ions pollutants down for the filter to capture. During our test, the comprehensive filtration mange to improves our indoor air quality within a few hours of runtime. Not bad for an air cleaning device that costs less than 100 bucks.

Keep it down

Fellowes AeraMax 100 air purifier is fairly silent given its moderate airflow output. Expect virtually zero noise at low speed, bearable noise at medium speed, and white noise at high speed.

For general use, set it to auto mode and let Fellowes AeraMax 100 decide what is the best mode for you. As for power usage, Fellowes AeraMax 100 consumes 37 watts of electricity at low speed and 51 watts of electricity at high speed. With 12 hours of operation, the average electric cost will be around $0.07 dollars per day, $2 a month, or $24 a year. Not Energy Star Rated but Fellowes AeraMax 100 will not stack up much on your electricity bill if Auto mode is enabled by default.

We highly recommend replacing the filter according to the service internal to maintain the filtration performance.
