Nordic Pure air filters have an actual size that is a fraction of
an-Inch smaller than the standard size (also known as "nominal
size"). The size printed on your air filter may NOT be the Actual
Size. With the 4-Inch and 5-Inch air filters there is a wider
variance between the nominal size and actual size for the
different manufacturers. Just check the "Actual Size" before
ordering. We manufacture high efficiency pleated furnace air
filters for your heating and air conditioning systems. We can
make most odd sized custom HVAC air filters for low cost and fast
free delivery. Our non-woven synthetic filter media will not
support the growth of mold or bacteria, keeping your home
ier. Our air filters use permanently charged electrostatic
material that helps dust cling to the air filter. This helps
protect your family from y causing , fine dust,
and cooking smoke, airborne spores, bacteria, and
some viruses. Changing your air filter is the first step in
insuring your HVAC system runs at its optimal level this season.
Generally, you should change your 1-Inch and 2-Inch air filters
every 30, 60, or 90 days. The 4, 5 and 6-Inch air filters should
be changed every 3 to 6 months. Standard air filters generally
ship within 2-10 business days. Actual shipping time will depend
on delivery address. We have been manufacturing air filters since
1960, and because HVAC systems have advanced through the years,
we have trekked the same course and improved our air filters too.
Try them, and we are certain you'll be pleased with our great air
filters.
From the Manufacturer
---------------------
The Nordic Pure MERV 8 anti-en pleated air
filters are made out of an electrostatically charged synthetic
material that draws airborne particulates to it like a magnet.
Electrostatic filters help trap airborne particles to protect
your family from , household dust, mold spores, and dust
mites. With each pass through the pleated filter, the air in your
living environment improves. Nordic Pure's synthetic filter media
will not permit the growth of bacteria or mold, therefore, making
your environment ier. This air filter will capture other
large particle contaminants to keep surfaces free of dust longer
in your home. MERV 8 air filters are comparable to air filters
with the MPR rating of 500-600 or FPR rating of Green. Particles
in indoor air are measured in microns, which are 1/1000 of a
millimeter. A human hair is about 70 microns wide. A MERV 8
Nordic Pure air filter captures airborne particles as small as
3.0 to 10.0 microns. This high performance air filter will
outperform non-electrostatic fiber-glass filters, washable
filters, and poly disposable filters. Nordic Pure air filters
have an actual size that is a fraction of an inch smaller than
the nominal size. With the 4-Inch and 5-Inch air filters there is
a wide variance between the nominal size and actual size. Almost
ALL filters are a fraction of an inch smaller than the nominal
size printed on the filter so it is best if you measure your
filter for the EXACT size and compare it to our "Actual Size".
Because of this, the filter you are replacing could be called a
16x25x4 and really be the same as our 16x25x5. This is why we ask
you to measure your filter so you aren't surprised if the filter
doesn't fit! Our MERV 8 four or five inch air filter should be
changed at least every 6 months depending on your environment.
Changing your air filter at the recommended time will help
maintain a y environment as well as keeping your air
conditioning and heating systems running efficiently.
