If you have a fiberglass throwaway filter, you should change it every 30 days. The filter helps keep your duct system, motors, and coils cleaner longer.

Here’s a great tip for remembering to change the filter:

When you get your monthly electric bill… change the air filter. If you do not change your filter, your electric bill may increase. The same is true if you own an electrostatic or electronic air cleaner. They should be washed every 30 days to remain efficient.

   Eric:

   J.R. did a great job getting our bedroom unit started. He also showed me how to clean the filters in the basement, but not all the downstream filter pads are present. He can tell you what is missing, and then you can determine if I need to do something to completely fill the opening…let me know.

   I recently checked the Gas Cu. Ft. and KWH from before and after we did our upgrade, and found that we’ve improved.

   Congrats.
