Why should I not clean a HEPA filter?
Some of you may be thinking of trying to clean your HEPA filter yourself in order to save a little money. But cleaning a HEPA filter is not the best of ideas for many reasons. Firstly, a HEPA contains many extremely thin mesh fibres which enable the filter to function but they are very delicate so any form of brushing or wiping could, very easily, cause damage. Even if you could be certain that the filter would not be damaged during the cleaning process, there are other reasons why cleaning a HEPA filter is not a good idea.
Cleaning a filter is a very dirty job. There is a high possibility that you will bring some airborne contaminants into your home or workspace unless you undertake the cleaning outside. Getting rid of those pollutants would be your biggest reason for using a HEPA filter in the first place. Any contaminants from the filter, that are introduced back into the air, may lead to new microbial growth or you may inhale some of the contaminants which could result in breathing difficulties.
