Without it, how can I determine static pressure drop? Whatever I can do to help the wife :) I'll be more than glad to post pictures, if it helps.įor what it is worth, I cannot find any technical specifications when searching for air filters. For what it is worth, I religiously change out the filter every three months but am willing to replace them every two months if it means less dusting around the house. Since my family and I are sensitive to allergies and are asthmatics, I am looking to purchase filters that a) reduces distribution of particles and b) does not negatively affect performance of my units. I am on the search for filters because, for whatever reason, I cannot reorder the sizes I need-not to mention, I've seen cheaper filters outside of HD. For the past year, I've previously purchased custom filters from Home Depot. This is a relatively new house located in Central Florida and I'd like to put something in that will not wear down the motor, thus shortening the lifespan of the units (can't live without our A/C here). I am looking to purchase new air filters for my Carrier units, models FX4DNF031 & FX4DNF025.
