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.

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. For example, your filter may have a nominal size of 16x25x1 but an actual size of 15½ x 24½ x ¾.

All of our product listings display the actual size in the description. If you are unsure or cannot find the actual size, please contact us at support@purefilters.ca and a customer service representative will assist you ASAP.

First of all you need to remove filter’s vent cover. Observe the arrows to know about the direction in which the furnace filter goes into the ventilation unit. Carefully pull the old furnace filter out and immediately put it in a garbage bag to avoid scattering of dust around. While inserting the new filter ensure that the arrows of the new filter goes in the same way as the old one. Finally replace the vent cover and any clips present.

It really depends because each environment is different and therefore requires different change frequency. We do have an entire guide on how often you should change your furnace filters, click here to read it.

There are a number of furnace filter brands that have gained quite a stellar reputation in the US. Most of these brands are sold through retail outlets all over the US and thus are easy to access.
