FAQ

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.

You can choose between 4 subscription options:

  • Every 1 Month
  • Every 3 Months

Which option you select will depend on the quantity of filters you plan to order and how frequently you plan to replace your filters. If you are unsure how often you should be replacing your filter, check out our guide here.

For example, if you have a 1 inch filter, you should be replacing it every month or so. You could select 12 filters and set your subscription to every 12 months. That way you get billed once a year, and have filters to change monthly.
