Today, I was asked about effective air cleaners, because wildfires have already begun to flare in North America.
Extensive global testing has found that a DIY #CorsiRosenthalBox will outperform almost every commercial HEPA unit while costing less to run.
For the US & Canada, the best source of filters to build one is Costco: Filtrete 1900, 2200, or 2500 models with at least one 20-inch dimension.
These units also help mitigate allergens and infectious aerosols like #Covid and Influenza.
