MERV and Your HVAC Air Filter

Let’s discuss how MERV, not Merv Griffin the talk show host from years past, but, MERV. The  Minimum Efficiency Reporting Value, and how it is used when measuring air filter effectiveness.  The MERV rating reveals how well your system’s air filter traps air particles and pollutants in your home air.

The MERV ranges from 1 to 20. 20 is typically for filters that can trap the tiniest particles, for example use in clean rooms. The correct air filter is important for two reasons:

  1. The filter traps pollutants in the air that could be harmful, including dust, pet dander, viruses, bacteria and mold.
  2. The correct air filter can keep your home comfort system running efficiently by increasing air flow and keeping harmful debris from building up in your comfort system.

Low cost filters have MERV ratings from 1-4.  Higher quality filters are rated from 9-12. Below is a breakdown of MERV ratings according to the EPA (Environmental Protection Agency):

MERV Rating Efficiently Traps:
1-4 Pollen, dust mites, sanding dust and carpet fibers
5-13 Dusting aids, fabric protector, mold spores and hair spray.
14-16 Bacteria and tobacco smoke
17-20 Used in clean rooms, pharmaceutical manufacturing, and around carcinogenic substances

Simon Peterson was my service technician. Very impressive young man. He explained everything first, did the work and gave me suggestions of what I could do in the future to extend the life of my unit. No high pressure, no bs. I highly recommend Hobaica and Simon for A/C repairs.

HIGHLY RECOMMEND this family owned, local business.

Gave clear and concise information about my AC problems; gave solutions at various costs & warranties, and was professional and courteous throughout the exchange. I didn’t feel pressured and I feel very confident as a long-time customer.

I had a leaky faucet and, because our regular plumber was out of town, called Hobaica because they have serviced our AC/heating units for years and I knew I could trust them to do plumbing work, too. Ryan Waters came over in just a couple of hours and quickly diagnosed and fixed the problem. I would recommend him to anybody who needs an honest and efficient plumber.
