The 16 x 25 x 1” furnace filter represents a great option for filter customers. Fitting most standard HVAC units with those dimensions, these filters are well built and ensure a higher quality of indoor air in the properties where they're used. Coming in a wide variety of styles – from pleated medias offering more surface area to trap air particles to more economical fiberglass options – these filters will improve a property's indoor air quality and increase the lifespan of the HVAC system itself. There is even a washable option that will allow for extended and repeated use over the life of the system.

Although the options vary for these discount filters, their general capabilities do not. All of these filters will trap lint and dust, pollen and dust mite debris from entering a property's air. In addition, as the MERV ratings increase, so does the amount of additional air particles the filters trap. These particles include mold spores, auto emissions, smoke, bacteria, tobacco smoke and pet dander. The MERV ratings for these discount filters range from a MERV 4 rating to a MERV 13 rating.

The pleated media technology also features a maximized surface area to trap these airborne particles – greatly increasing the lifespan of the product. Most of these filters will last three months prior to needing to be replaced.
