Buying Guide
- What filtration level do you need? Higher MERV (like 11–13) captures smaller particles but may reduce airflow in older systems. Match filter rating to your HVAC capacity and allergen exposure.
- How often should you replace filters? Most 1″ filters are recommended every 30–90 days depending on usage, pets, and environmental conditions. Higher dust loads may require more frequent changes.
- What size is correct? Confirm actual size versus nominal 20×22 to ensure proper fit. An incorrect fit can bypass filtration or cause HVAC issues.
- Is the filter made in the USA? If domestic sourcing matters, check the product description for manufacturing location and material standards.
- Consider pack size for savings and convenience. Multi-pack filters reduce replacement trips and help maintain consistent air quality.
