Think about using a transportable air cleaner.
In case you don’t have an HVAC system or simply need additional filtration, think about using a transportable high-efficiency particulate air (HEPA) cleaner. They’re essentially the most environment friendly filters available on the market for trapping particles that individuals exhale when respiratory, speaking, singing, coughing, and sneezing.
When selecting a HEPA cleaner, choose one that’s the proper dimension for the room(s). A method to do that is to pick a HEPA fan system with a Clear Air Supply Price (CADR) that meets or exceeds the sq. footage of the room by which it is going to be used. The bigger the CADR, the sooner it should clear the air. See EPA’s Information to Air Cleaners within the Residence pdf iconexterior iconfor extra data.
