Back to Homeowner Tips
You should change your standard furnace filter every 6-8 weeks. Use your own judgment, depending on your usage you may need to change it more often. Never let the filter get clogged, as this can cut down on the efficiency and/or cause damage to the unit.
All filters are not created equal! A standard 1" throw-away furnace filter will only trap about 5-10% of what passes through them. You can improve the efficiency of the filtration of your heating and/or cooling system by upgrading to either a media or electronic style filter. A high efficiency filter such as Cleaneffects by Trane can remove up to 98 % of airborne particles. By upgrading to a high efficiency air cleaner, you will also cut down on maintenance costs on the system since dirty systems are the #1 cause for malfunction.
