PrecisionAire and Flanders Furnace Filters
We all know we need to change our AC filters regularly to keep our units running optimally and keep the air in our homes clean during the warm months, but do you remember to change the furnace filter once it gets cold? Keeping your furnace in good working order saves money and energy!
A furnace filter has two main jobs:
- To keep airborne particles and dust out of the motor and internal components
- To help improve the air quality in your home by trapping dust, allergens and other indoor pollutants
We have a variety of sizes which are listed below and the following are characteristics and information about our furnace filters:
- Rated MERV 5 in 1"
- Rated MERV 6 in 2"
- Metal retainers on both sides for strength
- Polyester air filter fabric - no fiberglass
- Not available in custom sizes
- Made by Flanders PrecisionAire
Furnace filters satisfy the original purpose of having an air filter; a furnace filter will protect your HVAC equipment from getting dirty. While a furnace filter will keep your HVAC equipment clean which is a very important job, it will do little to improve indoor air quaility which has become a big issue with the number of indoor air pollutants present today. Pleated air filters will remove suspended particles that cannot be seen such a pollens, thus helping allergy sufferers. Carbon pleated air filters absorb irratating odors from the air. Baking soda pleated air filters freshen the air with proven sodium bicarbonate technology.
