How often should I change my furnace filter?
For most homes, we recommend changing your filter every 1 to 3 months. Homes with pets, allergies, or heavy HVAC usage may need more frequent changes—especially with higher MERV-rated filters.
What MERV rating should I use for my home?
MERV 8 to MERV 13 filters are ideal for residential systems. MERV 8 offers a balance of airflow and dust control, while MERV 13 provides enhanced protection against allergens, bacteria, and smoke particles. Be sure your system can handle the airflow resistance of higher MERV filters.
Are high MERV filters bad for my furnace or AC?
Not necessarily. It depends on your HVAC system’s design. Higher MERV filters trap smaller particles but may restrict airflow if your system isn’t rated for them. Contact us if you’re unsure—we’re happy to help you choose the best option.
What’s the difference between fiberglass and pleated filters?
Fiberglass filters (like MERV 1–4) offer basic system protection with minimal airflow resistance, but don’t trap fine particles. Pleated filters (MERV 8–13) capture more dust, allergens, and debris, making them a better long-term choice for indoor air quality.
