Air Filters 101
Air filters are an essential component of heating and air conditioning systems and come in many types. However, homeowners often have questions about their filters, such as what they do, when to replace them, and the benefits of replacing them on time. This is a quick guide about air filters, answering common questions about them.
How Does an Air Filter Work?
Air filters catch indoor contaminants and pollutants while allowing air to pass through a series of tiny openings in the filter. Once trapped inside the filter, these particles will no longer circulate throughout the home and cannot get stuck in the HVAC system and cause issues.
Common air-borne pollutants filters capture include pet dander, dust, and pollen. Once these particles build up inside the screen, filters must either be replaced or cleaned, depending on the filter type, to continue working correctly and keep indoor air clean.
When Is Air Filter Replacement Necessary?
A typical disposable air filter must be replaced at least once every three months. However, checking them monthly is recommended to see if they are dirty and need replacing. If homeowners live in households with multiple pets or excessive dust, they should change their filters more often to avoid pet dander and dust circulating throughout the home.
Washable filters are reusable and can typically be used for up to 10 years. Depending on the brand and type of filter, instructions will usually explain how they need to be washed and how often. Damp filters can produce mold and mildew, so it’s important to wait until they are dry before reinstalling filters.
What Are the Benefits of Air Filter Replacement?
Replacing dirty air filters has many benefits. Dirty air filters cause the HVAC system to work harder throughout each cycle, which leads to additional energy use that will increase monthly energy bills. If homeowners notice an increase in their energy bill, neglecting AC filter replacement may be to blame for the lost efficiency.
A dirty filter can also cause problems with the HVAC unit or uneven heating or cooling, so replacing dirty air filters on time helps improve home comfort and can help prevent repairs. Additionally, they improve indoor air quality and protect the household from potentially harmful pollutants. Keeping clean air filters in the system reduces allergy symptoms caused by indoor allergens such as pet dander and pollen.
