I’ve heard that electronic air filters lose efficiency rapidly in smoky or dusty environments, with some needing plates to be washed every 3 days. Also that they’re real noisy when dirty. That I know is true.
Also heard that they can put too much ozone into the air… a problem for those with asthma, weakened immune systems or lung disease.
I’m looking for a creditable place to confirm all this and any other possible problems with them. Anybody know of one?
