Furnace filters can make a huge impact on your comfort, your health, and the life of your heating and cooling system. Furnace filters are your first line of defense against allergens, dirt, mold spores, and particulates that get into your home. As the air in your home circulates through your ductwork, the filters catch the particles before they get into your furnace (helping keep your blower fan and coils clean) and into your living space (keeping the air you breathe clean). Not all filters are created equally, however. Some are designed to do their job better than others. That is why there are so many.
Some filters are washable. Washable filters should be cleaned according to the manufacturer’s instructions whenever they are dirty or whenever a cleaning is recommended.
Most filters, however, are disposable. They just need to be swapped out and thrown away when they get dirty or when the manufacturer recommends that you do it. Disposable filters can be made from a variety of materials and choosing the right one from a home improvement store or hardware store can be tough. We all know that clogged filters can restrict air flow and cause damage, but did you also know that buying a filter that is not compatible with your system can do the same thing?
ECS Comfort Heating & Cooling can recommend some great filters for you, but if you prefer to pick out your own, we encourage you to understand MERV ratings and their effect on air flow. MERV stands for Minimum Efficiency Reporting Value which rates a filter’s ability to capture particles between 0.3 and 10 microns (see the EPA’s article on MERV ratings HERE). Your system’s manufacturer has a recommended MERV rating for your system. Be careful not to use a filter that is rated too high as it may make your air handler work harder than it should to move the air through. This creates excess wear and tear and could damage your system.
