MERV = Minimum Efficiency Reporting Value
The original purpose of a furnace filter was
to protect the furnace and air conditioning coil. In recent years it
has become popular to also use the furnace filter to improve indoor
air quality. There are several different types available.
MERV 1 to 4 filters are the least effective
filters available on the market. They provide minimum protection for
your furnace and do little to improve indoor air quality.
MERV 5 to 7 filters are better but are usually
a 1” wide extended surface (pleated) type that is too restrictive to
air flow. This may cause your furnace to overheat or air conditioner
to freeze up. Clogged filters can destroy equipment and most
manufacturers advise against using 1” wide extended surface filters
for this reason. We encounter many failed furnaces and air
conditioners due to clogged filters.
MERV 8 to 13 filters require a 4 to 7 inch
wide cabinet (media filter) but offer the best protection and
filtration for your money. Once you have the media filter cabinet
installed, you can choose from a large range of MERV rated filters.
Media filters do an excellent job of protecting your furnace and coil
from dirt, which is mechanical equipment’s worst enemy.
MERV 16 to 20 HEPA (High Efficiency
Particulate Air) Filters are considered to be the best known air
cleaning devices. The EPA, American Lung Association and Consumer
Reports all recommend HEPA filtration.
The above descriptions are methods of
mechanical air filtration. Mechanical filtration is the best known way
to improve indoor air quality.
Some air purification equipment produce ozone
gas. Ozone gas is considered dangerous by the EPA, American Lung
Association, and Consumer Reports. These devices are classified as
ozone generators and their use is not advised. Ozone generators
produce NO known health benefits and ozone gas is corrosive.
