Furnace filters are designed to extend the life of a furnace while ensuring that clean air circulates throughout the house. These filters help maximize the HVAC system's efficiency while saving energy and reducing the time it takes to cool or heat the home. Minimum Efficiency Reporting Value (MERV) is the system used to rate the quality of furnace filters. Generally, the higher the MERV rating, the more efficient the filter will be. We recommend that residential filters be replaced every three months because dirty filters can compromise proper air flow. Regular filter changes can also help reduce utility costs.
Some furnace manufacturers put inexpensive fiber glass filters into their furnaces to remove airborne particles that may damage the fan and heating coil. Particle build-up can also decrease the overall efficiency of your furnace because it will have to work harder to pull air through the intake. More expensive filters can improve the air quality in your home by removing pollen, bacteria, and mold spores from the air. This is especially important if you or someone in your household suffers from allergies.
Recommendations can vary based on a number of different factors:
If you use a disposable fiber glass panel or electrostatic panel filter, you should have them changed anywhere from once a month to once every three months. Pleated filters generally last anywhere from three months to a year depending on how heavily they are used.
