Air Filter changing - easey and often

Examine the air filter at the beginning of each cooling and heating season and at the beginning of each day light savings time change. Write the date on the sides of new filters so you know when you changed them last.

A filter you can read a stop sign through is not a filter just a bigger trash collector. It wont stop particles that cause hay fever and irritate asthma. A filter that will help these items is one that you cannot see through except for light.

Keep a new filter on hand so you can compare the differences in color of the media. Some particles are so light colored they can only be seen by contrast.

A filter grille can usually be installed in under an hour (if the hole is correct size). Not only does it make changing a snap but encourages more frequent check ups. And this eliminates the indoor unit door not being put back in place correctly.

While changing look over the old filter for signs of moisture or special or different colors of particles so as to tell you about how good or poor the filter is doing. Wipe down the grille or door while open.

A washable filter is okay but you keep some of the dirt every time you put it back in place. Throwaway filters and electronic air cleaners are an excellent combination.
