Fellowes AeraMax100/ DX5 Air Purifier Quick Review

Little do most people know that Indoor air is at least 5-10 times more polluted than outdoor air. While getting good ventilation might be the quickest and cheapest solution around, it is not possible in most situations. An air purifier would be the next in line solution and Fellowes AeraMax DX5/ 100 can be the link. AeraMax 100 is effective at capturing influenza virus from indoor air based on independent testing. It is also the perfect model to reduce airborne pollution without costing much money. But what is the tradeoff for this tower air purifier? Does it have enough capacity to clean the air of an entire room? Find out more in our Fellowes AeraMax 100 review.

Fellowes AeraMax 100/ DX5 is made entirely from white plastic housing with a black vent on the top front, dual grey side vents, and a modern black control panel. The lightweight slim tower dimension means you can easily move the air purifier around via the back handle or place it anywhere in the home. There air vent surrounding the air purifier is unfortunately unadjustable unlike the AeraMax DX55 or DX95. Build quality is standard that should last for a couple of years on regular use. Other notable features you will find in Fellowes AeraMax100/ DX5 includes an AeraSmart Sensor (Blue = good air quality, amber = moderate air quality, red = bad air quality ), Auto mode, UL listed, AAFA, AHAM, CARB certification and 3 years warranty.

Fellowes AeraMax100/ DX5 fanspeed
Despite having a smaller tower body, Fellowes AeraMax100/ DX5 is fitted with a 4-Stage purification system that consists of a carbon filter that captures odors, a True-HEPA filter that captures smaller particles at 99.97% success rate down to 0.3 microns, AeraSafe antimicrobial treatment that protects the HEPA filter from mold/ pollen growth and finally PlasmaTrue ionizer that releases ions so surrounding airborne particles can be easily captured by the filter. The downside of a slim body is the small coverage where Fellowes AeraMax 100 can only purify the air up to 200 sq. ft. (small room equivalent). CADR is not great either with dust at 65 cfm, pollen 75 cfm, and smoke 68 cfm.

^ Replacement filters/ estimated cost
For around 120 after discount, Fellowes AeraMax100/ DX5 tower air purifier is quite a bargain as it comes with a True HEPA filter and a dedicated carbon filter. Most competitor models will cost more with poorer filtration. The filter replacement cost is also low at around 60 dollars annually. As for drawbacks, the lack of a dedicated pre-filter is surely the biggest miss while the drop in airflow performance is expected based on the price tag and size. Ignoring all and Fellowes AeraMax is not a bad air purifier for a customer that does not need something exceptional.
There is a very limited place you can buy Fellowes AeraMax100/ DX5 air purifier. Walmart, HomeDepot might carry the brand but not the air purifier. The official website does not have an e-commerce store last we checked, so naturally online retailer like Amazon is the best place to go. You will get a good discount, free shipping, 30 days return policy, and many bundled deal. Both colors are also available in Amazon so go check it out.
