More than 50 million Americans are suffering from various types of allergies each year. Our indoor air is full of dust, dirt, pollen, mold and mold spores, bacteria and other microorganisms which cause irritation to the body in some way. Over time, exposure to these irritating substances leads to coughing fits, sneezing, nausea, headaches, or even allergic reactions.
Like in cars, the air filter prevents impurities from getting into your engine; the air filter in HVAC systems prevents impurities from getting into your system. The furnace filter allows the air from your system to pass through to the duct system in your living space, while at the same time capturing invisible particles in the indoor air in hopes of not letting them pass through to the rest of the house.

Important Note: When you look for air filters online, make sure you compare their nominal size and actual size. The nominal size is typically printed on the cardboard edge of your air filter, which is slightly greater than the actual size in terms of inches. For example, if the nominal size of the filter is 18x25x2, the actual size will be 17.5×24.5×1.75
