Choosing the Right Filter for your Furnace

Choosing an air filter filter to buy for your furnace depends on how much you want to spend, what you’re trying to filter, and how consistent you are about changing the filter.

The minimum efficiency reporting value (MERV) scale goes from 1 to 16. Most residential filters range from 4 to 12. Furnace manufacturers prefer the standard spun fiberglass filters (MERV 2) because they filter out enough of the large particles to protect the furnace while providing maximum airflow. Maintaining the furnace manufacturer’s specified airflow is critical to achieving energy efficiency and maximum life from the blower motor and heat exchanger. An inexpensive MERV 4 filter captures 80 percent of the particles 50 microns and larger, but only 25 percent of the particles in the 3 to 10 micron range.

For most homeowners, a more expensive MERV 7 or 8 pleated filter provides a good balance between cost and filtration efficiency. These filters trap 80 to 95 percent of the particles 5 microns and larger – more than enough filtration for most homes.

Furnace efficiency is one thing. But if have family members with allergies or low-immunity issues, spend more on a high-efficiency (MERV 11 and higher) filter. Then just make sure you change the filter as recommended to protect your furnace.

High-efficiency filters capture 99 percent of airborne particles as small as 0.3 microns (bacteria and viruses, fumes and pollen). You’ll need to run your furnace fan full time to get the maximum benefit from a high-efficiency filter, and that will cost more. Figure the extra cost into your decision.

Finally, never switch from a fiberglass filter to a high-efficiency filter without first talking to your HVAC technician at Service Today. An Service Today technician can boost fan speed to compensate for the reduced airflow. Even then, you still have to remember to replace the filter regularly. A clogged filter can burn out the blower motor, damage the heat exchanger and cost you hundreds of dollars in wasted energy.
