Having a clean air filter helps your HVAC system run more efficiently and also improves indoor air quality. So, how often should you replace your air filters? This is a question that many homeowners ask, and the answer is dependent on the type of air filter you use and the conditions of your home. Depending on the type of air filter you have, you may need to replace it as often as every month or as infrequently as every three months.
Pleated Air Filters
The most common type of air filter is the pleated air filter. These filters are made of pleated paper and are designed to trap dust, pollen, and other airborne particles. Pleated air filters should be replaced every 30 to 90 days, or sooner if they start to look dirty. If you have pets or live in a dusty area, you may need to replace your pleated air filter more often.
Fiberglass Air filters
Fiberglass air filters are more affordable than pleated air filters but are less effective at capturing airborne particles and dust in the air. They should be changed every 30 days or less, depending on the environment in which they are used. If the filter is used in a dusty or smoky environment, it should be changed more frequently.
Electrostatic Air Filter
Another type of air filter is the electrostatic air filter. These filters are made of a mesh material that is coated with an electrostatic charge. This charge attracts and traps dust, pollen, and other airborne particles. Electrostatic air filters should be replaced every 90 days, or sooner if they start to look dirty.
If you have a forced air heating or cooling system, you also have a furnace filter. Furnace filters are usually made of fiberglass or pleated paper and trap larger particles, such as lint, dust, and pet hair. Furnace filters should be replaced every 90 days, or sooner if they start to look dirty.
No matter what type of air filter you have, it’s important to check it regularly and replace it when needed. A dirty air filter can restrict airflow and reduce the efficiency of your heating and cooling system. Having a clean filter helps your HVAC system to run more efficiently, and improves your indoor air quality, preventing allergies or respiratory problems for some people. Ultimately, how often you replace the filter depends on the type of air filter you have and the specific conditions in your home.
