What Is A Filter?

| My HVAC Price

In HVAC, a filter is a device designed to remove particles and contaminants from the air as it passes through the system. HVAC filters are commonly used to improve indoor air quality by capturing dust, pollen, pet dander, mold spores, and other airborne particles, preventing them from being circulated throughout the building.

People Also Ask About Filters

Why are HVAC filters important?

HVAC filters are important because they help maintain clean and healthy indoor air. By capturing and preventing airborne particles from circulating, filters contribute to a more comfortable and allergen-free living or working environment.

How often should HVAC filters be changed?

The frequency of filter changes depends on factors like the filter type, the level of pollutants in the area, and the system’s usage. As a general guideline, standard disposable filters may need replacement every 1 to 3 months, while higher efficiency filters like HEPA filters may have longer replacement intervals.

What are filters usually made of?

Filters are typically made of materials like fiberglass, pleated fabric, or HEPA (High-Efficiency Particulate Air) media, and they are installed in the air handler or return air duct of the HVAC system. As air flows through the system, the filter traps the particles and prevents them from entering the living or working spaces.
