Review on Airity Replacement Compatible Pre Filters Pre Filter by Chad Fox

My mother gave me a Honeywell HPA300 as a gift a few years ago because she was concerned that the air in my apartment was becoming stagnant and stuffy. (Also, my sinuses were constantly congested while I slept). The HPA300 has served me very well, helping with sinus congestion during sleep and eliminating the "cat house" smell in my apartment. I had to purchase a set of replacement filters, but was concerned about the noxious odor associated with Honeywell's official replacement filter pack (and price tag), so I did a little shopping around on Revain to find something more affordable for my needs. I stumbled upon these filters by accident and am happy to report that this is definitely a great filter set that is a lot cheaper than Honeywell filters. They are a little tight but fit my HPA300 with no problems. There was no bad smell or anything and I will probably get another set at some point in the future if I need another set of replacement filters!
