FAQs

Have Questions About Furnace Filters? Here Are Some Answers

What is a MERV rating? - MERV, acronym for "Minimum Efficiency Reporting Value" are ratings that are commonly used to measure the effectiveness and efficiency of a filter. MERV measures the ability of a filter to remove impurities from air as it passes the filter. This scale was designed by ASHRAE (American Society of Heating, Refrigeration and Air Conditioning Engineers) to gauge the effectiveness of filters. Click here to read our guide to MERV ratings.

Which MERV furnace filter do I need? - Each home is unique and therefore require a different MERV rating. PureFilters carries furnace filters with MERV ratings from 8 to 16. We wrote a guide on MERV ratings and how to select the best one for your home. Click here to read it.

How often do I need to change my furnace filter? - It really depends because each home environment is different and therefore requires different change frequency. Depending on where you are located, who lives in your home and various other factors, it can range from every 1 month to every 6 months. We do have an entire guide on how often you should change your furnace filters, Click here to read it.

What size is my furnace filter? - Always double check the measurements on your current filter to ensure you buy the correct size. Often times a filter has 2 sizes, the "nominal size" and the "actual size". The nominal size is purely for marketing purposes. Companies often round up or down the measurements in order to get a nice even number. The actual size is the actual measurements of your filter. We wrote a guide on how to find the correct furnace filter size, click here to read it.
