About Air Filter Sizing

There are two main ways to refer to air filters: their Nominal size and their Actual size. The Nominal size is a simplified version of the dimensions of the filter and is how it is typically labelled and sold. The Actual size, however, is the exact dimensions of the filter. Some filters may have the same Nominal size, but different exact dimensions, which is why the actual size is important when it comes to ordering filters. For more information, please see our article "Nominal vs. Actual Air Filter Size”

MERV 10 Can Capture

MERV 10 Efficiency

MERV 10 air filters offer an upgrade from MERV 8 without making your system work harder or adding resistance. They are great for removing many allergens and providing better indoor air quality to your home or business.

How often should I change this air filter?

While we give an estimated life of each filter, how often your air filter needs to be changed depends on your individual situation. How many people live/work in your space, if you have pets, and even your location and time of the year can all affect how quickly your air filter gets dirty. We recommend checking your filter once a month to keep track of how dirty it’s getting. Check out our video explaining this in more detail on our “Air Filter Change Frequency” page.

Great price

The filters arrived safe and sound. No damage to box or anthing inside. I have used these filters for the last year and I think they are great! This is the 2nd box I have ordered and I am so pleased with the quality. I used to spent almost 2x as much for the other filters I was using with the same merv 10 and I am now saving money and they are just great. I appreciate the honesty and the service from this company!! Truly a satisfied customer!!!
