Buying Guide: Key Purchase Considerations
-
<liSize and fit: Verify nominal vs. actual dimensions to ensure a proper seal in your HVAC slot. Common sizes include 12x12x1 and 16x25x4, with a range of actual measurements around those baselines.
<liFiltration level: Choose MERV ratings that balance filtration with airflow. MERV 8 filters are solid for general dust control, while MERV 11 filters offer stronger allergen defense for households with pets or smoke exposure.
<liMedia type and pleats: Pleated media increases surface area and filtration efficiency. More pleats generally mean better capture but ensure your system can handle the airflow.
<liPack size and replacement cycle: Multi-pack options (2-pack, 4-pack, 5-pack, 6-pack) help simplify maintenance and budgeting for regular changes.
<liSystem compatibility: Some filters are marketed as compatible with Lennox or Honeywell models; confirm your furnace or AC unit’s requirements before purchase.
<liEase of installation: Look for filters that slide in easily and have clear directional arrows indicating airflow. This reduces installation time and ensures proper operation.
<liDurability and warranty: Higher quality pleated filters may offer longer service life and better edge construction, which can reduce frame sag and fit issues over time.
