Understanding MERV Ratings
Filters are rated by MERV (Minimum Efficiency Reporting Value) — the higher the rating, the better the filtration, but also the more restrictive the airflow. If you need better air quality due to allergies or asthma, avoid using high-MERV 1-inch filters. They clog faster, restrict air, and can trigger limit faults in your furnace.
What Ed Recommends
“I always prefer that homeowners use a simple 1-inch fiberglass filter rather than restrictive pleated filters. They’re inexpensive, safe for your furnace, and easy to change.” Even 4-inch media filters — while better than pleated 1-inch filters — can still raise static pressure and temperature rise if ductwork is undersized. The key is balance — clean air without overworking the furnace.
When to Consider an Air Cleaner Upgrade
If you or your family suffer from allergies, dust sensitivity, or respiratory issues, you can benefit from an electronic air cleaner or media filter system.
These systems:
- Remove up to 99% of airborne particles
- Work with your existing HVAC system
- Require less frequent maintenance
- Keep your coils and ducts cleaner
