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

John and Jared came out today to take a look at my air conditioning unit. I live in a condo where I can’t see my unit but noticed some water dripping from the roof. They weren’t just on time, they were a little early which helped free up the rest of my day.They found that the system was running as it should be and let me know that the water was dripping because the condensation line was disconnected. Super easy fix with a little bit of glue, and they did not create worry where there was none just to add to the bill.As if that wasn’t good enough, they were incredibly nice and easy to talk to. Not nice because it’s required- just really genuine people. I was not expecting to have such an easy and inexpensive experience in Phoenix during hot, muggy monsoon season. Thank you both for making my day!

We recently had our air conditioning go out on Tuesday and on Friday a new unit was installed. The service has been fantastic. Could not have asked for a faster more friendly company.Zach and Gio were amazing in getting the unit installed and walking us through the new thermostat.

Grayson came out and was on time, and very nice. He took extra time to diagnose a potential problem, and even re-secured some wire mesh (to keep birds out) that had been blown off from the wind. He answered all my questions, will do business with hobaica again.
