AIR CONDITIONING FILTERS
The traditional furnace filters are designed to protect the blower motor and equipment. Clogged, dirty filters block normal air flow and reduce a system's efficiency significantly. With normal air flow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. This is the part that concerns me the most.
Some types of filters are reusable; others must be replaced. They are available in variety of types and efficiencies. Fiberglass filters, which cost under $2, are designed solely to protect the blower motor and equipment in the furnace.
But, did you know that high efficiency filters not only protect the blower motor and equipment, but work like tiny magnets to capture up to 30 times more pollen, pet dander, smoke, dust and other allergens than standard fiberglass filter. The air in your home is continually re-circulated through the filter, so it gets cleaner and cleaner.
When a house is being remodeled or painted it is one of the most crucial times to change the filters even more often. Whenever you are in a house remodeling mode be sure to change the filters and save that HVAC system.
