I see purifiers made with box fans and four filter panels. Anyone have first hand experience? Are they worth the effort?
I did the version with two filters and a box fan to make a little triangle and that worked great for me. Even just slapping a filter on a box fan is better than nothing. Last year the smoke wasn’t too bad and by the end of it my filters were pretty brown. Highly recommend it.
Filters are pretty cheap and come in 3 packs at Costco if you’re looking to pick some up.
Thanks, I'll look at Costco
We did that for a number of years and they do work OK. Two or three years ago, we finally broke down and bought standalone air purifiers when we had a newborn. I know they're expensive, but if you get them off season they're much cheaper. Might consider it if you're going to be in Seattle for the long haul, unfortunately... They work well, are pretty energy efficient, and are much quieter than the box fans.
Ikea sells some really neat air purifiers, even one that can be used as a small table!
Neat, I'll check that out
Didn't think about noise
No first hand experience but I hear good things and Wikipedia has some info for further reading. https://en.m.wikipedia.org/wiki/Corsi%E2%80%93Rosenthal_Box#Efficacy
