Review on VEVA Air Purifier Filter Replacement - High-Quality HEPA Filters, 3 Pack with 4 Precut Activated Carbon Pre-Filters, Compatible with Honeywell HPA300 Purifiers & Replacement Filter R by Patrick Matin

I have two HPA 300 and two HPA 100 and I use Veva filters on all of them. I originally had an HPA 300 and loved it, but changing the filters was a hassle. I've tried them and they worked so well when I needed to replace some of my old air purifiers that I later bought another 300's and two 100's just because I knew I could get these replacements for them. I live in the Central Valley of California and we have one of the worst flight ratings in the United States. Not only is the air bad year-round, but smoke from wildfires across the state collects in the valley. At some times of the year the air outside smells only of smoke for weeks. You go into people's homes - it smells of smoke, you go into shops and offices - it smells of smoke. But not in my house, it didn't smell of smoke. If, like me, you have multiple air purifiers in your home, I recommend rotating them while you change your pre-filters so the HEPA filters wear out more evenly.
