The smoke from California fires caused air purifiers to be sold out at many locations. Today I am going to show you how to use what you have or can probably still get, to the room air clean. Compared with the expensive air purifiers on the market, these DIY air purifiers are equivalent but at a much cheaper price.
Three reasons they are cheaper:
1. if you already own a fan, then you don’t have to buy another fan.
2. when buying filters, you can buy whatever size is most suitable for your fan, or is cheaper
3. unlike air purifiers, the filters as well as fans can be bought cheaply (because both items are high volume commodities).
For example both the fans and the filters can be bought for about $15 each.
