HVAC filters do more for indoor air quality than most people realize. They capture the vast majority of airborne dust, pollen, and other contaminants floating about your home, but most filters need to be replaced every few months to effectively clean the air. Does your house take a while to cool down when you come home from work? A dirty HVAC filter might be to blame.

When to Change Filters

A good rule of thumb for changing conventional filters is once every six months. However, there are many exceptions to this rule. If you generate a lot of dust with home construction, have several furry pets, or regularly come in dirty from working outside, you will likely have to replace the filter more regularly.

High-efficiency filters remove an even higher percentage of particulates from the air, but they also clog more quickly, and you’ll want to replace them once every three months. In either case, check your filter monthly, and replace it as needed and double check your manufacturer’s recommendations for the best air filter for your system.

Good for Your Health

Filters are a boon to allergy sufferers. While keeping your home clean is important for minimizing allergy symptoms, an air filter can make the difference when trees start blooming. Filters can also improve asthma symptoms while reducing the risk of developing a respiratory infection.

Improving Energy Efficiency

A dirty filter slows airflow through your HVAC system, making it work harder and for longer periods of time. At best, you’ll spend more on your energy bills. At worst, the extra wear and tear could cause a system malfunction, which could cost hundreds of dollars to repair. Clean filters maximize airflow, protect your air handler from dust buildup, and keep energy costs low.
