Why are electrostatic filters better than HEPA filters?
A good filter that removes particles from the air is not all that is needed for an air cleaner to be effective. The filter must also allow a large quantity of air to pass through it. Electrolux Air cleaner´s electrostatic paper filter has an open structure. A great deal of air can pass without causing noise. This is the reason that Electrolux Air cleaner works quietly even though it is so effective.
