Changing your furnace filter regularly has a great impact on your health, and the health of your HVAC system. Indoor air is polluted with contaminants — as much as five times more polluted than the air you breathe outdoors. The right furnace filter works to prevent contaminants from reaching your living areas, and promotes effective airflow throughout your HVAC system and your home. Your trusted, local HVAC contractor can assist you in finding the best furnace filter option to keep your home and system healthier.

Pollutants are lurking in your home

The products you use each day, the particles you track in from outdoors, even your own body — each of these sources contribute to the pollution inside your home.


The average home is affected by a number of pollutants, including:

• Dust mites
• Mold
• Auto Emissions
• Germs and viruses
• Dead skin
• Pet dander
• Pollen and other allergens
• Chemical fumes
• Smoke


Your filter is your first line of defense


A high-efficiency filter that is rated MERV 8 or above has the power to trap airborne contaminants before they travel through your system and back into to your living areas. This keeps your home clean and clear of particulates that can aggravate asthma and allergies, and worsen respiratory illnesses or colds. Furnace filters rated MERV 13 and above help remove illness-causing germs, viruses, and bacteria from your home, keeping everyone healthier.


Make filter changes a priority


Over time, the trapped contaminants build up on the filter, restricting airflow and the filter’s ability to remove new pollutants from your indoor air. A dirty filter also creates strain on your HVAC system, causing it to work harder to move conditioned air to your living areas. In turn, dirty filters cause excess energy use, increasing your energy bills.
It is recommended that you change your filter according to the manufacturer’s recommended schedule, though depending on the conditions of your home as well as the outdoor air quality, you may find it necessary to do so more frequently. Standard 1-inch filters need to be changed every 1 to 3 months, while high-efficiency filters should be changed approximately every 6 to 9 months. Staying on top of furnace filter changes will positively affect the health of your family and your HVAC system by improving your indoor air quality.
