Central air conditioners have one or more filters that clean the air and ensure good air quality as the unit circulates between indoor and outdoor air. These filters are generally made of spun fiberglass or pleated paper or cloth, encased in a rectangular cardboard frame. Fiberglass filters are the cheapest and are common in older systems, while newer models use thicker pleated filters. At its most basic function, an air filter removes impurities such as dust, pet dander, or even bacteria from the air that flows through the system.
This not only improves the air quality inside your home, but it also protects your HVAC system from potential damage. The air filter in your HVAC system works to remove particles from the air in your home and keep your air conditioning and heating running smoothly. It can be difficult to locate in some HVAC systems, but you can usually find the air cleaner in the return air duct or ventilation grille. We measure how well an air filter removes dust, pollen and smoke from the air, and we see how freely air flows through the filter at any fan speed.
Air passes through the filter (or filters) and the filter material traps contaminants before they can circulate around your home. Some HVAC systems aren't strong enough to push air through more restrictive filters that block smaller particles, that is, those with a higher MERV or CADR rating, which can reduce airflow and cause your home to heat and cool less efficiently. Proper maintenance of air filters is essential for providing clean air in your home and keeping your HVAC system working properly. This may involve replacing them or washing them regularly.
