Not all filters are created equal
You know enough about your home’s HVAC unit to know that you
need to change your filter regularly but when you see all of the available
options how do you know which one is right for your home? All types of filters have different functions
and knowing about the various types will help you choose the one that is right
for you.
What is MERV, MPR,
FPR?
First of all different brands of filters use different
rating systems and numbers. These rating
numbers are used to tell the consumer the amount of particles and pollutants
that a filter can capture and hold. The
higher the number the more particles the filter captures.
·
MERV Rating (Minimum Efficiency Reporting
Value): Established by the American Society of Heating, Refrigerating, and Air
Conditioning Engineers, MERV rates a filter’s ability to capture and hold
particles and pollutants. The numbers are from 1-12 for residential filters.
·
MPR (Micro-Particle Performance Rating): rating
system developed by 3M that measures the amount of microparticles the filter
captures that are smaller than 1 micron, the numbers range from 300-2800
·
FPR (Filter Performance Rating): rating system
developed by The Home Depot. It utilizes
a color code and number scale (4 to 10) that is similar to the MERV rating.
Washable Air Filters
Air filters that are washable may seem like a more “green”
option but overall are not recommended.
They have low ratings and therefore do not trap as many particles. The MERV rating for washable filters is
usually between 1 and 4. They require additional maintenance as well. Also, fungus can grow on the filter if not
completely dry before putting back. Washable
filters do little to help allergy sufferers.
They also cost more money than disposable filters.
Fiberglass Air
Filters
Fiberglass air filters have the ability to trap larger air
particles from your home but are not effective in capturing smaller pollutants
and allergens. Even though they are the least expensive option, the air quality
in your home will not be improved. They
also need to be replaced more often. The MERV rating is typically between
1-4.
Polyester and Pleated
Air Filters
Polyester and pleated air filters are the most effective at
trapping all types of particles from your home. These filters capture and trap pollutants and
particles but do not restrict airflow in your HVAC unit. Pleated and polyester filters have a much
higher MERV rating of 8 to 13. Easy to
find and replace, pleated and polyester air filters are the best option for
most homes, especially for those with allergy sufferers.
