During the chilly winter conditions in Harrodsburg, KY, it’s typical to use a furnace to get maximum comfort. To maintain healthy air quality, the specifications of the furnace filter must match the industry standards. Here’s why choosing the right filter is important and what you should look for when selecting a furnace filter.

Size of the Filter

When shopping for a furnace filter, make sure that the filter is an exact fit. A loose filter will cause small air particles to sneak through the opening, making the filter less effective. If you’re not sure about the size, ask an HVAC technician to guide you.

The Thickness of the Filter

The thickness of a filter also plays an important part in keeping the system more efficient. As a rule of thumb, a thick filter is better. Check your manual for the right configuration or get help from an HVAC service provider.

Pleated Filter

Pleated filters are more efficient than non-pleated filters. According to the EPA, some pleated filters are 99.7% efficient in cleaning dust, pollen, and bacteria up to 0.3 microns. In simple words, a pleated filter offers much more surface area and contains smaller pores to capture tiny airborne particles.

Filter Efficiency

It’s important to get a filter that has a sufficient MERV rating. Most pleated filters have a MERV rating of 10, which is ideal for most homes.

If you live in an area that experiences a higher level of air contamination, seek a filter with a higher MERV rating. Similarly, if you or someone in the house has asthma or they’re allergic to pollen and pet dander, get a more efficient filter.
