question : How effective are electrostatic air filters for the prevention of allergies? Are they worth the high cost?
Using air filters in the ventilation system of a dwelling can reduce allergen exposure. Electrostatic filters are effective in removing dust and small particles from the air. There are a number of other filters that are equally effective. These include the high-efficiency particulate air (HEPA) filters. There also are high-quality paper filters that are quite efficient in filtering dust and small particles from the air.
If the source of allergen remains in the home, however, these air filters are usually not enough to eliminate allergy symptoms. For example, if a person is allergic to a cat that's continuously producing large amounts of sensitizing substances in the home, an electrostatic air filter and other air filters generally aren't going to solve the problem. The only effective remedy in that case is to remove the cat from the home.
The other important factor in considering an air cleaner is that it must be large enough to adequately remove dust particles from the air in a particular dwelling. Generally, air cleaners attached to the main ventilation system of dwelling — usually the furnace system and/or the central air conditioning system — work better than free-standing air cleaners.
