Buying Guide
Clean air matters. Choose the right filter.
I swapped my old filter for a higher‑MERV one. The air felt fresher right away.
-
Size: Pick the exact dimensions printed on the old filter. A tight fit stops air leaks.
-
MERV rating: Higher numbers catch smaller particles. For most homes, MERV 8‑11 is a good balance.
-
MPR rating: This is another way to show efficiency. Higher MPR means better dust capture.
-
Filter type: Electrostatic filters hold dust with static charge. Media filters use a dense paper web.
-
Airflow compatibility: A filter that is too dense can slow the furnace. Check the unit’s manual for limits.
-
Lifespan / change interval: Most filters last 30‑90 days. Set a reminder to keep performance high.
-
Allergy / asthma rating: Look for “Allergy‑Friendly” or “Asthma‑Certified.” These help sensitive people breathe easier.
-
Price and value: Compare cost per filter and expected life. A modest price plus long life gives the best value.
Tip: Keep a spare pack nearby. Replacing the filter on schedule saves energy and keeps air clean.
Bottom line: Match size, choose a suitable MERV/MPR, and replace regularly for healthy air.
