AeraMax 300 Air Purifier Review Features

The AeraSmart sensor immediately detects and purifies the polluted air using a True HEPA filter. This so-called AeraSafe treatment is antimicrobial and it eliminates 99.97% of the airborne particles as small as 0.3 microns.

This includes pollen, ragweed, as well as other allergens such as viruses, germs, dust mites, mold spores and smoke.

This purifier is certified as asthma & sensitivity friendly by the Asthma and Allergy Foundation of America.

The unit made by AeraMax has a special mode just for cold and flu season. It is good at capturing these influenza viruses lingering around at home (based on independent testing). The AeraMax 300 is recommended for medium to large sized areas from 300 to 600 square feet.

AeraMax 300 Large Room Air Purifier Review

The Fellowes AeraMax 300 is an air purifier that is actually ionizing the air in the room. This purifier offers 4 stages of filtration, giving you the maximum cleaning efforts for your home. The ionizer can’t be disabled, so we cannot recommend the AeraMax 300 to those with breathing problems.

The 4-stage air purification system begins with a carbon pre-filter that removes smells and captures the larger particles. The HEPA which is a “true” filter removes small particles from the air. You can think of dust, pollen, and smoke.

Air passes through the AeraSafe filter which is antimicrobial, to reduce the growth of bacteria in the trueHEPA filter. Finally, the PlasmaTrue ionizer catches escaping particles which will get caught on the next pass as they leave the filter. This purification system successfully removes indoor pollutants in medium to large size rooms in a convenient and easy way.

It is necessary to note that the EPA warns against using ionizers too much, as charged particles can be harmful to your lungs. Especially for individuals with breathing-related issues. Air filters with permanent ionizers typically have a timer that is scheduled to work at specific times.

For example when you’re away from home, to limit the exposure of charged particles. The AeraMax 300 DX95 doesn’t provide these features, which means that you’ve got to manually switch the unit on or off.

This air purifier has an auto mode, which may be the default setting when you turn the unit on for the first time. An air-quality sensor is included, thanks to that you can know a number of pollutants in the air. Based on that information you can adjust the fan accordingly. Last, the AeraMax DX95 will come with a warranty that is three-year.

Fellowes AeraMax 300 Purifier Review

Let’s have a closer look at the features:

Area Coverage

The AeraMax 300 claims to successfully get rid of pollutants from the air in large rooms of 300 to 600 square feet. It will come with a CADR rating of 191 for smoke, 196 for dust, and 188 for pollen. To be safe, apply the “two-thirds” rule of thumb. The CADR for tobacco smoke is 191 so it fits a room with an area of 286.5 square feet.

“The CADR score of the AeraMax 300 has improved a lot from older AeraMax Air Purifiers.”

True HEPA Filter

The True HEPA filter eliminates 99.97% of microbes .3 microns or larger all on its very own. These microns consist of allergens, viruses, and cigarette smoke. The AeraMax 300 highlights a 4-step filtration system, comparable to what medical facilities make use of.

One of these methods services a carbon filter, which takes away odors and large particles from the atmosphere. This 4-step filtration system is one of the most successful systems currently available.

The drawback of these filters, needless to say, is that they must be changed, and multiple stages of filtration indicate you have several filters to repurchase. Filters usually last for 6 months of constant use, but heavily polluted air can always fill them up faster than expected.

One of the AeraMax’s special features also maximizes efficiency for allergen and pollutant-rich months. While this function is immensely useful, it will likely use up a filter even faster.

“A true HEPA filter is included in the AeraMax 300 air puffier, which plays a key role to remove allergies, asthmas, viruses, bacteria, odor, and smoke in a adequate way.”

Carbon Filter

Coming with a 4-stage purification system, this device also has a carbon filter to get rid of odors and catches large airborne particulates. It’s suggested to exchange the carbon filter every 3 months under normal practices.

The authentic carbon filter (4 packs) for this model will cost you around thirty dollars. One HEPA and one carbon filter are delivered with the AeraMax 300 Air Purifier.

PlasmaTRUE Technology

This device has an ionizer feature integrated to more effectively collect airborne contaminants. The ionizer produces negative ions that will connect to dust. Bigger particles are created which can be captured by the filters much more easily. If you’re worried about the health dangers of ionization, you can switch off this feature.

Filter Indicator

The AeraMax 300 will come with a replacing filter signal light that alerts you when to replace the True HEPA filter and carbon filter. Exchange the True HEPA filtering when the signal changed to red. Similar can be applied for the carbon filtration.

AeraSmart Sensor

Featuring the AeraSmart sensor, it can instantly change the fan speed to keep your air filtered. There is an air quality signal that reveals the home air quality. The blue level shows the air is clean. Yellow/Orange indicates the air quality is weak. The red color implies high levels of pollutants in the air.

“AeraMax 300 unit is perfect for people who suffer from asthma and various allergies.”

Aera+ Mode

This Fellowes AeraMax 300 air purifier has a 4-speed fan, from “low” (6 Watts) for silent, energy-efficient operation to “turbo” (86 Watts) for the most successful cleaning. You can put the AeraMax 300 in the Aera+ mode, which boosts the air turnover by fifty percent to get rid of even more contaminants from the air in your room.

Cover Range

As opposed to numerous other air purifiers, even those in a similar price range, the AeraMax 300 can clean up to 600 square feet, making this air purifier ideal for large rooms.

It can be difficult to find a device that can clean such a large air volume, making the search for the best air purifier even more difficult for people looking to clean air in a room larger than a simple bedroom. Nevertheless, the AeraMax 300 is able to purify anywhere from 300 to 600 square feet, so if you’re looking to purify a smaller space, this unit might still match your needs.

Design and build quality

The black/ white contrast design with blue lights is perfectly carried through with a bottom stand that gives this DX95 model a modern-day look. In contrast to other brands that provides a variety of color options, the Fellowes AeraMax 300 DX95 will come only with a black or white color combination option.


Along with its Allergy and Asthma Friendly certification from the Allergy and Asthma Foundation of America, this unit is AHAM and CARB certified. The AeraMax 300 is also UL listed and Energy Star Certified, which is a good combination of certifications, and it’s always crucial to look at 3rd party reports prior to purchasing an air purifier.


Fellowes provides a 3-year limited warranty to make sure your new air purifier does what it’s supposed to do. Looking at the length of the warranty is an effective estimation of how long the device is expected to run at maximum potential.

Fellowes AeraMax 300 Review

Customer Reviews

I used this air purifier for a month now. This unit intakes air from two sides and releases the purified air from a vent at the top. You can put the AeraMax300 next to a wall or in a corner. This device has certainly lessened my dust allergies substantially and has made my home a lot more comfortable.

I will not have the AeraMax 300 on when I have the house windows open for a while. It is silent on the lowest setting but it continues to be effective and is good for those who like some white noise. This device gets clearly louder with each setting but I personally don’t care about it at all.

The auto setting operates great when cooking to help reduce the smells. I like the convenience, the dimensions of the unit seems just fine.

The handle is also practical when I feel like placing the AeraMax somewhere else. It is very lightweight as well, but that depends on you. I will be buying a second one later on. Also, some testimonials have mentioned a plastic odor.

I remember a somewhat sterile scent when I first switched the AeraMax on, but I gave it a week and have not smelled it since. Maybe some people did not get rid of the plastic wrap from the filter before switching on.

Another review
I always bought air purifiers with the cleanable long-lasting filters. while they functioned quite well the first few days after cleaning them, I have to say I will by no means go back again. Despite the fact that you have to replace the filters the AeraMax 300 more than worth it.

I have a 750 square feet 1 bedroom condo and while this unit says it will do 300-600sqft it works very well in my place.

I will have many buddies over during the weekends and the vast majority smokes, I did not allow smoking indoors but with this, I keep it on “auto” and it helps to keep the air clean to the point my non-smoking friends are amazed how well it purifies the air.

The next morning you don’t even smell the smoke smell like I have smelled in earlier times. I will definitely buy another one of these if I ever move up to a bigger place and most definitely would suggest it to anyone.

Air Recommended Air Purifiers

Our Pick Perfect for bedrooms, playrooms, and living rooms, the Coway Airmega AP-1512HH is one of the best-performing, most durable, and most economical purifiers we’ve tested.

Most Popular The Levoit Core 300 air purifier has some strong suits, but in our opinion it falls short of carving out a meaningful niche for itself. Its ideal use would be in a small bedroom occupied by someone who is sensitive to noise.

Also Great With high end air cleaning performance and a whisper quiet fan, the Winix 5500-2 is the perfect combination of power and finesse. It cleared airborne particulates out of our smokey testing room faster than any other model.
