Let’s start with the key features of the AeraMax 300 air purifier.

4 Stage Purification

How does this product work?

Just like other brands, the AeraMax 300 is equipped with a series of filters that target pollutants and allergies. Each filter captures these particles depending on their sizes. The larger ones can’t get pass through the carbon filter, while particles as small as 0.3 microns (e.g., pollen, dust mites, mold spores) are trapped in this device’s True HEPA filter.

The HEPA filter contains the AeraSafe antimicrobial treatment, which provides built-in protection against odor-causing bacteria and other microorganisms. At the last stage of this filtration system is Plasma true technology, which is designed to create an ionized field to totally eliminate pollutants.

Auto Detecting Technology

This air purifier has the AeraSmart Sensor, a system that allows this device to monitor the air quality of the surroundings and then to automatically adjust the fan speed to clean the air.

Blue level indicates that the air is clean. Amber means the air quality is poor, and red means the room has a high level of pollutants.

4-Speed Setting

Choose from among 4 settings – low, medium, high, and turbo. There’s another mode, the Aera+ Mode, which is for allergy, cold, and flu seasons.

AAFA Certification

The AeraMax 300 is certified by the Asthma and Allergy Foundation of America to be asthma and allergy friendly.

AeraMax 300 Air Purifier Review, Consumer Feedback


Check Price


This section of our AeraMax 300 air purifier review presents a summarized consumer report of what previous buyers have experienced with this device.


Yes, the AeraMax 300 air purifier can help ease the symptoms of allergies. Many consumers have reported a positive experience with it, claiming that they can breathe better and that they no longer have sinus problems.


The sound this machine makes gets louder as the speed settings get higher. On the lowest setting, the sound it makes can be classified as a “hum.” On the highest setting, it is quite loud, and you probably don’t want to use this setting at night. The good news is that, according to several people, you may not really need the high setting as most of them keep it running at the highest speed.

Dust collection

Does it eliminate dust? While it doesn’t totally remove dust from your home especially those that found their way and have built up on furniture pieces, it helps reduce dust from the air.

Pet hair collection

Dog and cat owners have shared their experience, and the general feedback is that this air purifier does pick up some pet hair, but because it’s not a vacuum cleaner, you’ll still see some stray hair on the floor. In fact, at least two people said that once the hair is on the floor, the AeraMax 300 will no longer pick it up.


Does this product last? One person has had his unit for more than 2 years.

Odor reduction

In this video, a mom talks about how the AeraMax 300 has helped reduce the paint smell in their basement. She says that at first, her husband was skeptical, but after two days of usage, he says he has noticed a difference, with the air smelling fresher.

How about cigarette smoke? According to the company, the AeraMax 300 is designed to remove 99.9% of smoke particles in the air. However, this air purifier will not able to sufficiently pull odor out of upholstery, so you’ll still notice some smoke odors.

Plastic smell

Not all, but several consumers have reported smelling a strong plastic odor when they first used this device. It should go away after some time. Some people said this smell disappeared after a week.
