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

Our AC blower motor broke twice since mid-June. Hobaica came to replace it twice since then. However, we noticed that our AC wasn't blowing enough air as it did previously, but all technicians from Hobaica couldn't figure out what was wrong with our system or even claimed that it was working properly. Our system could not maintain the set temperature during the afternoons and was constantly running, causing abnormally high electrical bills. Finally, after multiple technician visits, Binh T came and found out that the blower motor was not programmed properly and replaced it with a new one for the "third" time. Our AC is finally blowing sufficient amount of air from the vents!! Thank you so much, Binh T, for being professional and knowledgeable on this matter! We cannot thank you more.

Travis did a great job replacing the Moen cartridge in my shower. He even offered to install the escutcheon, stop tube and handle that I expected to do myself. I appreciated that. Travis is professional, does high quality work and is an overall great guy to work with. It was a job well done.

Travis did an exceptional job of installing my new WiFi thermostat and made sure everything worked before he finished the job.
