All forced air heating systems come equipped with an air filter located between the ductwork and the furnace. Most homes with boiler systems lack ductwork, and therefore do not have air filters.
Air filtration is the process of removing dirt — like dust, lint, pollen, and pet hair — from the air in your house. By trapping the dirty stuff, your air filter makes your indoor air cleaner.
The air filter also plays a vital role by preventing dirt from being drawn into your furnace and air conditioner. If the innards of your equipment become plugged with dirt, air flow is restricted. Insufficient air flow stresses major parts, which can lead to major damage and major repair bills.
We sell many types of air filters. We can help you determine which one is best for your home.
This is the most common filter, generally made of paper, fiberglass, or other material attached to a rigid frame. Air can pass through the filter material, while dirt is captured on the filter surface.
We sell high quality media filters to match just about any system. Our filters are superior to those found in big box outlets. Not sure how frequently to change your filter? Just give us a call to speak with one of our experts. Changing your filter on schedule is one of the best ways to prolong the life of your furnace and air conditioner!
Filter efficiency is measured by the “MERV scale,” a measure of the filter's ability to remove particles from the air. Numerically, the scale goes from 1-16, with filter density increasing as MERV ratings go up. In general, the higher the MERV rating, the better the filter captures dirt.
Note, however, that some furnaces and air conditioners are not designed to operate with ultra-dense, high MERV filters. To avoid equipment damage, always follow manufacturers' filter recommendations.
