Heating System Filters
Heating system filters play an integral role to your furnace system’s performance. The wrong filter choice (one that doesn’t fit properly or diminishes air flow) can increase your energy bills and lead to repairs that could have been avoided. The optimal filter can help improve your home’s air quality and help you save money.
That’s why we suggest cleaning your reusable filters or replacing your HVAC system's filter at least four times a year, or as often as once a month during peak usage times.
Which filter should I buy?
You will have a variety of filter options to choose from according to your specific HVAC system. Though all air filters are designed to liberate airflow while removing dust, contaminants, pet dander, pollen and more—some are more efficient than others.
Before deciding on a model, review the filter’s minimum efficiency report value (MERV). On a scale from one to 20, these ratings tell you how effectively a filter gets rid of dust particles, its lifespan, and how much it restricts airflow. Some of the most common filters include:
- Disposable fiberglass filters are the least expensive—but also the least effective. These filters are capable of blocking only large dust particles, which means smaller particles such as pollen and mold can pass right through.
- Washable "electrostatic" filters have a static charge to attract dust, dirt and other airborne contaminants. While these filters are slightly more effective than their disposable equivalents, they still don’t block the smaller particles.
- Pleated "allergy" filters use a denser mesh material to more effectively trap and eliminate potential allergens like pollen and mold. Most are between 35% and 50% efficient.
- Electronic air cleaners create an ionized electrical field that "magnetizes" pollutant particles, eliminating virtually all pollen and mold spores, up to 94% of smaller particles, and up to 80% of airborne viruses.
- HEPA furnace filters are generally considered to be the "gold standard." These filters are used when clean air is vital, like in hospitals and electronics manufacturing facilities.
