Many people are not aware that the air inside our homes is five times harmful than the air outside. Because of airtight home and office building constructions, the airborne pollutants are trapped inside, making the contaminated air unable to escape. Clean air is even more important inside the home than it is outdoors. Home air filters, also called as "furnace filters", keep the coils and heat exchanges on the heating and air conditioning system clean, which otherwise make the system work harder. Home air filters contain high efficient motors and anti-microbial filters, resulting in healthy and clean air in home or office.

There are manifold types and styles of home air purifiers, including HEPA, carbon, zeolite, UV light air purifiers, and more. Some air purifiers have filters, and some use stainless steel rods to collect contaminates.

Home air filters work by drawing air through the layers of different air filters. The air first passes through a pre-filter where large particles are removed. Then the air passes through a coconut shell activated carbon filter that absorbs gases, chemicals, odors and vapors. After this absorption, the air enters two anti-microbial filters for further filtration. Then the air goes on to the 80 square feet HEPA media where 99.97% of all allergens and particulate larger than 0.3 micron are removed from the resultant air. From this HEPA media, the clean air is released back into the room. The size of airborne particles that a home air purifier captures is measured in microns. A micron is hundred times smaller than a human hair and is obviously not visible to the naked eye.

The most important thing to remember about home air filters is to change them regularly. Upgrading and properly maintaining home air filters is easy and helps improve indoor air quality.
