About
A DIY filter was developed during the pandemic and the filter happens to be better than most filters on the market today. Instead of wasting money of expensive machines with expensive filters and creating a lot of waste, make your own filter with a $20-30 Lasko box fan, part of the cardboard box it comes in, 4 furnace filters (I just use the strongest AC filters), a knife, and some tape. The filters should be replaced annually.
For something cheaper, you can tape an AC filter to the front of the fan.
