An HVAC air filter is an important component of many heating and cooling systems.
As air circulates through a home, the filter helps capture airborne particles before the air continues through the HVAC system.
What Does an HVAC Filter Do?
Depending on the filter and system, it may help capture particles such as:
- Dust
- Pollen
- Pet particles
- Household debris
Where Are HVAC Filters Used?
Filters can be found in systems such as:
- Furnaces
- Central air conditioners
- Return air grilles
- Heating and cooling systems
Why Filter Maintenance Matters
A loaded filter can affect airflow and may make an HVAC system work harder.
Checking the filter regularly is therefore an important part of routine HVAC maintenance.
Conclusion
An HVAC air filter is a relatively simple component, but it plays an important role in both air circulation and system maintenance.
