Not All Air Filters Are Created Equal

Did you know that you have options now when it comes to choosing an air filter. This is not a ‘one size fits all’ scenario anymore. You have options to choose from that can impact the air quality in your home, and we’ve done the research for you to help decide which is best for you and your home.

According to Consumer Reports, some essential terms you should know when shopping for air filters are as follows:


This is the Micro-Particle Performance Rating developed by 3M. It rates the filters on the ability to capture airborne particles smaller than 1 micron. The best filters have MPRs between 1500 and 1900.


Home Depot uses its own rating system on a scale of 1 to 10 called the Filter Performance Rating. The higher the number the better it filters.

Now, when it comes to choosing a specific filter for your house, you have a variety to choose from. Here is a list of some available options, along with their individual benefits.

BASIC/GOOD (MPR 100, FPR 4-5) air filters will likely capture the most common air contaminants such as pollen, dander, dust and dust mites. These are the most affordable and minimal of the filtration options. If allergens or odor are not a concern – this could be a sufficient solution for your home.

The next step would likely be a “better” or “clean air” type filter that has an MPR of 300-600 or an FPR of 6-7. These filters are just a step above the basic, however this will also trap mold, which is a common household occurrence and a major allergen for many.

For added coverage, upgrade to a more substantial filter specifically designed for allergen filtration (MPR 800-1200, FPR 8-9). These filters have the ability to clean the air as it passes through the filters, eliminating most key allergens such as smoke, mold, pollen, pet dander, and other microscopic elements that tend to float through the air.

The top teared filters (MPR 1200+, FPR 10-12) are your best chance at complete air cleaning technology. If you are looking for a filter that can do it all, these are your best bet. Not only do filters in this range clean the air, ridding your home of dust, mold, mildew, smoke, smog, bacteria, and pet dander, but they also have the ability to eliminate all household odors and airborne viruses as well.
