Do I Really Have To Change My Air Filter Often?

November 25, 2015

f you want to save money and extend the life of your home’s heating and cooling system, the answer to the question is yes. It takes just a few minutes every few weeks to replace the filter in your system.  Neglecting to take care of this simple HVAC maintenance task has many negative consequences and most of them will end up costing you a lot more than a new air filter.

The air filter removes pollen, dust, and other airborne impurities to improve indoor air quality. A clogged filter decreases air quality by allowing these impurities to circulate freely throughout the house. Poor indoor air quality makes your home unhealthy because it triggers allergic reactions and asthma attacks.

Polyester and pleated filters are usually the best for residential applications. Traditional fiberglass filters only remove large particles and are less efficient than other options. Some filters are made of cellulose, plastic or metal.

You should change your standard disposable air filters approximately every one to three months, depending on the filter type. Check the specifications provided by the filter manufacturer to determine how often you should replace yours. You may need to change it more frequently if you smoke in the house or if you have pets. You may also need to change the filter more often if it is located in a high traffic area.

Most homeowners can handle an air filter change without help from a professional. Check your HVAC system’s owner’s manual to determine the right filter type and size to purchase. Before changing the filter, turn off the HVAC unit. Look for the filter on the side of the unit and slide it out. Slide the new filter into the slot paying attention to the arrows to ensure the filter is facing the right way.

Changing your air filter on a regular basis is the most effective and affordable way to protect your investment in your home’s heating and cooling system. Regular maintenance allows your system to operate at peak capacity when you need it most.
