Review on Airity Replacement Compatible Pre Filters Pre Filter by Sonny Nevers

I bought this because I was staying at friends house in California with 2 major issues: 1. The house is old and dusty and I'm hyper allergic to dust mites or anything else these old places have and 2. The Deterioration in air quality due to recent forest fires is very noticeable indoors even after windows and doors are closed. Luckily my friend already had a Honeywell filter. It fits and works great! It's a bit cheaper than other filters and it was enough for me (also as a super allergy sufferer).
