Frequently Asked Questions
How Often Should I Change My Air Filter At Home?

What Is a MERV Rating?
MERV stands for Minimum Efficiency Reporting Value. Air filters are measured by the MERV rating, the higher the rating the more contaminants the filter can capture.

“Been doing business with PAF inc as a HVAC contractor for years providing large amounts of filters for churches, customers, and to referrals… you can’t beat these guys service and pricing.”

“Always amazing service. Always welcomed with a smile. Will take future orders or orders on the spot. Very timely with all orders. They welcome companies and public sales alike. If they don’t have a filter you need they will make it for you.”

“I absolutely love this place! i’ve been coming here for years.They sold me a Metal frame for my filters which is much more cost-effective and environmentally friendly. I just paid $23 for eight filters! The service is excellent, but you can order them ahead and pick them up.”
