Buying Guide
Air quality matters at home. A good filter helps you breathe. It also saves your system.
I changed my filter each season. I saw less dust on shelves. My kids breathed easier.
- Size: Must match 20x25x1. Check the frame size. Use the exact dimensions.
- MERV rating: Pick the right level. MERV 8 works for most homes. Higher MERV catches smaller particles.
- MPR rating: Look for a high number. It shows filter power. MPR 700 is strong.
- Filter type: Pleated filters catch more. Static pull adds extra capture. Fiberglass is cheap but weak.
- Lifespan: Check how long it lasts. Three months is common. Some last up to twelve months.
- Price: Compare cost per filter. Low price may mean low quality. Balance cost and performance.
- Brand name: Trust known makers. Good brand gives reliable filters. Reviews help decide.
- Airflow: Filter should not block air. Low resistance keeps system safe. Look for “easy flow” notes.
- Allergen control: Pick high MERV if you have pets or pollen. It traps dust, dander, pollen. Helps asthma and allergies.
- Fit: Ensure the filter fits the frame. A tight fit avoids leaks. Check actual size dimensions.
