How Often Should You Change Your Home HVAC Filter?
As homeowners, it’s essential to ensure that our living space remains safe, comfortable, and healthy. A critical component of this is the HVAC (Heating, Ventilation, and Air Conditioning) system, which regulates the air quality and temperature of our homes. An often overlooked aspect of HVAC maintenance is the regular changing of the air filter. In this article, we’ll explore how often you should change your home HVAC filter and why it’s so important.

HVAC filters are designed to trap dust, pollen, pet dander, and other airborne particles. This not only helps in improving air quality but also protects the HVAC system from damage.
Types of Filters:
- Fiberglass Filters: These are economical but need to be changed more frequently.
- Pleated Filters: Offer better filtration and last longer than fiberglass filters.
- HEPA Filters: High-Efficiency Particulate Air filters can remove very fine particles. Ideal for those with allergies.
Frequency of Changing Filters
Table: Filter Type vs. Recommended Change Frequency
| Filter Type | Change Frequency |
|---|---|
| Fiberglass | Every 30 days |
| Pleated | Every 3-6 months |
| HEPA | Every 6-12 months |
Note: These are general guidelines. The frequency can vary based on specific home conditions.
Factors Affecting Filter Life:
- Allergies: If someone in your home has allergies, consider changing filters more frequently.
- Pets: Homes with pets may need to change filters more often due to pet hair and dander.
- Usage: High usage of the HVAC system, especially during peak seasons, can shorten filter life.
- Air Quality: Homes in areas with high levels of dust or pollution might require more frequent changes.
