The Ultimate Guide To MERV Ratings For Furnace Filters

Many Canadians don’t realize that there are some drastic difference between the types of furnace filters you can use in your home.

You may have come across something called a “MERV rating” and different furnace filters appear to have a different rating.

When browsing for furnace filters you typically see most filters are rated from MERV 8 to MERV 13. Of course there are still some retailers that carry the low quality fiberglass filters too. But assuming you value a higher level of air quality in your home, you will probably find yourself comparing MERV 8 and MERV 13 filters.

Turns out, depending on your unique situation, you may require a specific type of filter for your home.

Well, in order to understand the difference, we must first get acquainted with how the MERV rating scale works.

What’s is a “MERV” rating?

MERV stands for minimum efficiency reporting value and it is basically a measure of how effective a furnace filter is. Although the scale ranges from MERV 1 to 20, the majority of furnace filter retailers only carry filters between MERV 8 to 13.

To put it short, the higher the rating, the more particles the filter will trap and therefore the higher the quality.

So which MERV is appropriate for your home? Well it really depends on your needs.
