Filtration that supports comfort and HVAC performance
A properly selected air filter improves indoor air quality while protecting HVAC components from dirt buildup. Pamlico® air filters are designed to provide dependable filtration while maintaining airflow when matched correctly to the system.
Selecting the right size and MERV rating is key. Higher filtration can help with dust and allergies, but airflow and static pressure must remain within equipment limits to avoid performance issues.
If you’re unsure which filter to choose, we can help match the correct Pamlico option to your return grille, filter rack, or air handler.

How often should I change my HVAC filter?
Most 1" filters are replaced every 30–90 days depending on dust, pets, and system runtime. Inspect regularly.
What MERV rating should I use?
Higher MERV improves filtration but increases resistance. Choose a rating your system can handle without airflow loss.
How do I confirm my filter size?
Use the printed size, then measure length × width × thickness to confirm actual dimensions.
