Has anyone tried this self made air purifier? They’re called Corsi Rosenthal box

Looks like enough money and trouble that I would just get a cheap hepa filter if it were me. I bought a Honeywell hpa300 iirc. It's ran perfectly for over ten years. Filters are cheap on Amazon. It saved my ass when the mold was at its worst. The last few years I haven't used filters much (my home d

I bought a $900 unit and bought over$3k in filters and the fan went bad after a few years and they would not provide a fix. Only offered me a small discount

What's the best air purifier or brand to buy for home currently that has HEPA filters?

Honeywell makes good air purifiers. They're manually controlled, so not a smart device, but I have 4 of them in my home running 24/7 and they have been going for 6 years without any problems. I bought the HPA300 model. They need regular prefilter changes, and annual hepa filter changes. The replacem

These guys demonstrate the real impact of air purifiers

Damn, prices have really gone up since we got them. Check the filter prices too though before you buy; they add up real quick replacing them 1-2x/year. We have two of the HPA300s for the basement and first floor, and the smaller one in the bedroom. Maybe went a little overboard when the wildfire fir
