Review on DerBlue Replacement HEPA Filters: Improve Air Quality with AER1 Type Total Air Filter, HAPF30AT for Holmes Purifier HAP242-NUC by Samantha Allen

I have asthma, I have over 30 allergies, a cat and I have a cat window all the time (long story). Buying a Holmes air purifier was the best investment ever! These replacement filters are good. My air purifier came with filters but when it came time to replace mine I couldn't believe how expensive they were. This is very much! And they work, I have photos and videos to prove it. They usually last around 4 months. Mine does last about 3, but that's not bad considering I never give my air purifier a break and there are a lot of pollutants around me. All I can say is it's worth it. It feels like the elephant sitting on my chest is finally gone! I can breathe deeply again! doesn't matter
