A pre-filter is a type of air filter that removes large particles from the air, such as dust, dirt, and hair. Pre-filters are the first step in an air purifier’s air filtration process. A pre-filter keeps the main air filters from becoming clogged with debris, allowing them to trap microscopic pollutants.

WHAT EXACTLY IS
IT ?
Need to choose an air purifier pre-filter that will
effectively clean the air in your home.

2. A pre-filter is a type of air filter that
removes large particles from the air,
such as dust, dirt, and hair. Pre-
filters are the first step in an air
purifier’s air filtration process. A pre-
filter keeps the main air filters from
becoming clogged with debris,

pollutants.
What exactly is
a Pre-Filter?
Pre-filters are used in air
purifying equipment installed in
homes, commercial buildings,
transportation systems, and
public areas.

3. A pre-filter captures large particles
before they enter the air purifier
unit. Pre-filter air filters function
similarly to sieves. Air flows
through the pre-small filter’s pores
or netting, while dust, dirt, and hair
become trapped on the pre-
surface. filter’s

A pre-filter serves two
purposes: it captures large
particles and extends the life of
the main internal filters. Pre-
filters are used to protect the
main internal filters so that
they can filter out smaller
contaminants, extending the
life and efficiency of the main
filter.

5. Pre-Filter Varieties
Mesh and carbon pre-filters are the two types
of pre-filters. Only solid particles are trapped
by a mesh pre-filter. A carbon filter captures
both solid particles and gases. The type of
pre-filter in an air purifier is determined by the
other internal filters. A mesh pre-filter air
filter works like a sieve. It is composed of
small pores or netting that allow air to pass
through while blocking large particles such as
dust, dirt, hair, and other debris. A mesh pre-
sole filter’s purpose is to capture large
contaminants before they enter the air purifier
unit.

6. Do You Need a
Pre-Filter?

7. Do You Need
a Pre-Filter?
A pre-filter is an essential part of an air purifier
because it sieves large particles that can impede
or shorten the life of the filtration system. A pre-
filter is good to have because it protects the main
internal filters from damage.
With that said, you don’t necessarily need a pre-
filter on an air purifier; however, it does improve
the efficiency of the unit. Therefore, we always
recommend that you choose an air purifier that
has at least an activated carbon filter that acts as
a dual pre-filter and odor remover.
The next best option would be an air purifier with
its own dedicated mesh pre-filter that works to
protect the main HEPA air filter and activated
carbon filter.

8. PRE FILTER / PRIMARY
AIR FILTER
If your filtration system has pre-filters,
it's good practice to change them
about 6 times a year, or every other
month. This will keep everything in
your filtration system running
smoothly, and will ensure that none of
the cleanroom system parts past the
pre-filters experience excessive
contamination.

9. CARBON AIR FILTER
Carbon air filters are a special kind
of furnace filter that works on a
molecular level to help reduce the
severity of unwanted odors in your
home's air supply.
