How to Choose a Furnace Air Filter

Who doesn’t like to breathe clean air in his own house? Everyone knows that having a clean home also means having clean air to breathe inside your house.

An air filter is also known as a furnace air filter. The air filter is responsible for maintaining the heating and air conditioning system’s coils and keeping the heat exchange clean.

The air filter of your home should be cleaned regularly since if its coils and heat exchange are dirty, the unit needs to work harder and in return the machine may eventually give up on its own.

In choosing an air filter, you need to consider how frequently you must clean it. Every unique furnace air filter has different cleaning intervals and filters which are installed in a newly built or in a remodeled house. It must be cleaned frequently since it collects extra dust and air residue.

Another thing you must consider in choosing an air filter is its material and style. The performance of the unit is dependent on the size and density of the material used in making the unit.

The quantity and size of the dust or materials being filtered also affect the overall performance of an air filter. You can also try to pick a filter that has pleats made of various materials.

These are good in catching dust particles and other materials since it has a larger surface area. There are also available filters with pleats that were charged electro-statically to attract and keep in place other minute particles.

To select the appropriate size and shape of the air filter to be used, you can ask a professional what is best for the size of your home. Huge houses (3,000 sq. ft. or more) need a 4” air filters while small houses need 1” thick filters.

The Minimum Efficiency Reporting Value (MERV) must also be considered in choosing a furnace air filter. The indicated MERV of the unit will be the basis of its capacity to filter and hold particles of sizes 3 microns to 10 microns.
