Understanding the Difference Between FPR and MERV Rating

When it comes to residential filtration systems, two classifications stand out: the FPR and the MERV. In my opinion, the FPR system is a more comprehensive classification system for air filters compared to the MERV and MPR systems. To communicate information about the filter's performance, both the MERV and the FPR use numerical values. The FPR system takes into account the pressure drop and dust-holding capacity of air filters, aspects that MERV and MPR systems do not address.

The FPR ratings range from 4 to 10, while MERV ratings range from 1 to 16. The MPR measures ratings based on sizes from 0.3 to 1 micron. In addition, filters with an FPR rating of 4 to 5 will not restrict airflow as much as filters with a higher FPR rating. However, if the MERV rating is too high (above MERV 1), it can increase system backpressure and block air flow through the central air system, worsening the efficiency of the air conditioning system. Filterbuy offers MERV 8, MERV 11 and MERV 13 air filters and ovens, which cover the normal range of household needs by providing clean air and, at the same time, protecting air conditioning equipment. MERV 8 filters usually filter 90% of airborne particles, MERV 11 can remove around 95%, and MERV 13 can block approximately 98%.The main drawback of using filters with an FPR rating of 8 to 9 is that they will reduce airflow more than filters with a lower FPR rating. Therefore, it is important to consider both the FPR and MERV ratings when selecting an air filter for your home.

Filterbuy offers a variety of options for residential filtration systems including MERV 8, MERV 11 and MERV 13 air filters and ovens. These cover a wide range of household needs by providing clean air while protecting air conditioning equipment. For example, MERV 8 filters usually filter 90% of airborne particles while MERV 11 can remove around 95% and MERV 13 can block approximately 98%. The main disadvantage of using filters with an FPR rating of 8 to 9 is that they will reduce airflow more than those with a lower FPR rating.

Therefore, it is important to consider both the FPR and MERV ratings when selecting an air filter for your home in order to ensure optimal performance. Overall, understanding the difference between FPR and MERV ratings is essential when choosing a residential filtration system for your home. By taking into account both pressure drop and dust-holding capacity as well as considering both FPR and MERV ratings when selecting an air filter, you can ensure that your home has clean air while also protecting your air conditioning equipment.
