Replace your filter for a healthier winter home

This time of year, we hear plenty about “cold and flu season.” But, many in the health profession tell us it’s not that there are more “cooties” floating around this time of year; it’s more about closing ourselves up tightly in our homes during the colder months. As a result, air quality indoors—and the concentration of those cooties—is often worse than air quality outdoors. One important step can result in a healthier family and a healthier home.

The air filter on your heating, ventilation, and air conditioning (HVAC) system needs to be replaced every 1-3 months to keep the air in your home clean and flowing freely. A high quality air filter is the best choice to remove mold, pollen, and other microscopic particles from the air.

The air filter is usually found behind the air return grate mounted on a wall or in the floor or ceiling. The filter may also be located in or near the air handler unit.

To replace an air filter:

• Turn the heating system off and wait until it stops running
• Remove the cover on the air return
• Take out the old air filter
• Write the date on the new air filter
• Insert the new air filter in the return, making sure the arrow on the edge of the filter is facing in the direction of air flow. For filters with wall and floor mounted returns, the arrow should point in toward the return duct. For filters mounted in the ductwork near the air handler, the arrow should point toward the HVAC unit.
• Put the cover back on the air return
• Turn the heating system back on

To make it easier to replace next time, put a sticker on or near the return with the size filter you need to buy and when to replace it.
