Size is the first thing to determine when shopping air filters. You can determine the height and width by taking your current air filter out and measuring the largest outside dimension (length), then measure the next largest dimension (width), followed by the maximum depth. All should be measured to the nearest 1/16”.
After you’ve determined size, think about what kind of environment your air filter will have to process. Do you smoke, have kids or pets, or do you suffer from indoor/outdoor allergies? All of these internal air components will effect what type of air filter you buy. Luckily, the filter industry has many options that will fit your exact needs.
Filters should be changed monthly unless you have a large media filter such as a Space- Guard®. If you have a home that may be prone to dust, if you have pets or if you have a smoker in your home more frequent changing may be required.
A properly sized system is very important. A system that is too big for your home will cool or heat your house quickly, but you probably won’t feel as comfortable as you wish. In the case of air conditioning, the thermostat sensed the desired temperature before the system could get the humidity out of the air. You feel sticky and humid and your house is susceptible to moisture and mold issues.
A system that is too small never can keep up and will never cycle off. This greatly increases your energy bills and substantially reduces the life of your system. A properly sized system isn’t just based on square feet of your home. Many factors go into determining the size of the system including thickness of the walls, number and size of windows, thickness of insulation, basement and attic use, house orientation, and many other details.
