You hear it all the time, change your air filters. Have you ever wondered why? There are very good reasons why you should change them timely.
The first big reason is air quality
Your home’s air can be a rather messy place, often worse than the air quality outside. That means that breathing can be difficult, especially if you have issues like allergies, asthma or COPD. Indoor air pollutants can include pet dander, mold, dust mites, gas-fired appliances and combustion devices. If you don’t already have allergies or other breathing issues, you can develop them. You could also suffer chest tightness, sore throat, coughing, shortness of breath, asthma attacks and watery or itchy eyes. Air filters, especially HEPA filters, clean all that out of the air in your home.
Protect your heating and air conditioning system
Another reason you need to regularly change your air filters is to protect your heating and air conditioning system. The air filter helps protect the interior components of your HVAC system. How your system works can be hurt by the buildup of debris and dirt. It makes it work much harder than it has to. That stress on the system can increase the risk of your HVAC unit malfunctioning or shorten its lifespan. The EPA says that switching a dirty air filter with a clean one can reduce your HVAC unit’s energy consumption by as much as 15 percent.
Those dirty air filters can also cause fires
Furnaces are designed to maintain safe operating temperatures, and airflow is part of how your system keeps itself at the right temperature. If the air is restricted, the system can overheat, and has been known to cause fires.
Poor airflow not only affects not only air quality, but also air pressure
If the flow of air is restricted with dirt and debris, outlying areas of your home get little heated or cooled air. Then you turn up the system, overworking it more.
So don’t wait to change your air filters. Your health and your HVAC system will thank you.
