Clean and replace furnace filters regularly to keep your heating system running efficiently. Dirty and dusty filters are the reason for half the repair calls to service technicians.
When buying replacement filters, there are different types to meet your needs. Keep in mind that some filters are better than others at keeping allergens out of the air.
-Disposable or washable filters work fine at keeping your furnace clean. They collect large particles, but may not keep out mold spores, pollen and other allergens.
-Pleated filters may be a better choice for reducing allergens. They can cost as little as $5 or $10. But be prepared to pay more for more effective filtration.
-A high-efficiency pleated air filter costs around $250 to $450. Contact your service technician for information and help.
-Electronic air cleaners work best at removing dust, mold and other pollutants from the air. They're more expensive, too. They may range in price from $600 to $900. But the cost may be offset by lower health care bills and a more comfortable indoor environment.
