How To Purify Air the Easy Way with DIY Box Fan Filter

Purify your air with a DIY Box Fan Filter. Easy to do, affordable, and fairly effective. I've been doing this for 2 years now and have noticed a significant improvement in air quality, especially during wildfire season. A single fan can purify a standard size room, so you may need multiple fans to cover larger areas or multiple rooms.
