Guess it helps to clean the filters

Air return in hall The pollen in Florida this year is especially heavy. There's been no rain for over a month, and the trees seem to have been almost snowing down a yellow-green blanket of pollen. Cars have been coated, and many people, Shirley included, have had a real tough go of it. Well, we finally realized that we'd neither replaced nor cleaned the filters in our air returns for close to a year. For those who don't know, they should be cleaned or replaced every month! We have this large 18x30 inch unit in the hallway ceiling, and a 12x12 inch filter goes in the air return in each bedroom.

First Shirley started to vacuum the incredible amount of dust and yuck from the large filter. But then we decided to go to Lowe's and buy some new electrostatic filters and just replace the lot of the cheap filters. Shirley's still suffering a bit from the pollen, but at least we know that we're not wasting as much energy on heating / cooling, and we're not recirculating as much crud through our home's air.
