Electronic air cleaning filters require a professional to modify duct work and install electrical wiring in your system. While it is more expensive, it s highly effective for people with high sensitivity or allergies. To select the right filter for your needs, ask a dealer. When selecting an air cleaning dealer, be sure to find someone who handles the system you need. If you re not sure what you want, discuss your situation with several dealers before making a decision.
Dealers can specialize in certain systems or do primarily residential work over commercial.
Be sure the dealer you choose has experience with your system and ask about any guarantees offered. For systems which install into your duct system, find out about maintenance service available. This is important in keeping your system working. Finally, your dealer s reputation and years in business should also be considered. For more information, consult your local dealer.
