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

Wonderful experience! He came on one day and fixed what he could and then scheduled us the next day to repair the problem! He was very friendly and outgoing!

Scott Dale was very professional and knowledgeable during an inspection of my HVAC system. I was very comfortable during his visit and he shared helpful information and pictures and patiently answered all of my questions. I highly recommend Scott and appreciate having a technician of his caliber representing Hobaica.

Saw Mike Varela outside a neighbors house. Stopped what he was doing to answer my 100 questions lol. Definitely a difference from past experiences with HVAC companies. Wanted to share my good experience. Would recommend to a friend.

All around super happy with my service - called and got an appointment to help with some pipe issues that same day. Brandon was great and while I hope to never have to use the service again, I would be giving them a call before anyone else! :)

Gabriel and Angel were great installing my new AC system. They showed up early and were professional and efficient the entire time. A slight electrical issue came up early, and they quickly had an electrician come out so the project would not run late. They took the time out to answer my questions and explained the steps they were taking during the install. My entire experience with this company and Gabriel and Angel in particular was positive. I would definitely refer them to others!
