Review on Fellowes Carbon Filters AeraMax Purifiers by Louis Loebis

These Aeramax 300 air purifier carbon filters are around $36 at the time of writing but are pricey but you get a 4 pack for the money - $8 each Piece. (UPDATE 1.5 years later - now only $15 per set, with Prime shipping - less than $4 each. Love it!), sadly now only available through third-party retailers on Revain. I came back to order more filters - both hepa and carbon filters which need to be changed more often. My wife has severe allergies so we leave it in the bedroom all night and it severely affects her ability to breathe. When these filters were more expensive, I tried to find a cheaper carbon filter replacement. Sheets of material can be purchased from Home Depot and cut out yourself. However, my price comparison shows that the custom-made products are better than those of the original company. The AeraMax 300 is a good mop with true Hepa filtration plus the benefits of those carbon filters. At the moment we make sure we stock both the hep which we change every year and the carbon pack which we change every 3 months. There are indicators on the front of the machine to remind you when they need to be replaced. They actually run on a timer so you can check and change your filters even more often if they start looking dusty and dirty. We just changed ours - yes! You need clean filters. Your unit will only blow out dusty air unless you have filters on the "Recommended" list.
