When it comes to air filtration, it's important to understand the difference between the various rating systems. FPR and MERV are two of the most common rating systems used to measure the efficiency of air filters. FPR stands for Filter Performance Rating and is a system developed by The Home Depot for brands sold in its stores, including Honeywell. MERV stands for Minimum Efficiency Reporting Value and is a system developed by the American Society of Heating, Refrigeration and Air Conditioning Engineers (ASHRAE).The FPR system uses a color code and a numerical scale (4 a) that closely resembles the MERV classification.
The numerical scale ranges from 4 to 10, with 10 being the highest rating. On the other hand, the MERV classification system ranges from 1 to 16, with 16 being the highest rating. Generally speaking, FPR 6 — 7 equals merv 8 — 11 ratings, while FPR 8-9 equals the MERV 11 rating. MPR and FPR systems are only useful when applied to their respective brands. The MERV classification system is beneficial for homeowners looking to change the brand of air filters or compare available options.
If you want to upgrade your home air filter, the MERV 13 is our favorite, but any MERV 11+ means a healthy home. Fortunately, you won't need to make a long list of pros and cons of MERV versus MPR or spend hours comparing FPR to MERV. The higher MERV rating also causes static pressure problems in your home and can overload the system. US Home Filter can supply you with the best and most efficient HVAC filters available and all are labeled with the nationally regulated MERV classification. In general, each of the filter classification systems mentioned above can be useful for homeowners. Each provides a breakdown of an air filter's capacity and a comparison measure based on classification.
Whether you choose the MERV classification system, the MPR system, or the FPR system, make sure you choose an air filter with an appropriate rating based on your home conditions. If you have pets and allergies, a low-rated air filter won't do any good. A filter with a sufficient MERV rating will capture common household particles, such as dust, pollen and mold. The higher the MERV index (between 1 and 1), the more and smaller particles will seep out of the air. Household air filters with higher MERV values should also be changed at a higher frequency because of their greater efficiency and ability to capture particles.

With this information in mind, you can make an informed decision about which type of air filter is best suited for your home.
