Hello, I just bought a HEPA air purifier holmes (literally just bought), and in a few hours started making a strange electric hum. I think it is coming from the ionizer, because when the ionizer is off does not make this noise. Is this normal or is it a problem with the machine? Has anyone else had this problem? Thanks in advance. No matter, I am rid of the thing anyway. Today I learned that … You have made a good decision.
