The Filter Performance Rating (FPR) is a weighted average for each filter, which is then rated on a scale from 1 to 12, where 1 represents the lowest performance and 12 the highest. The MPR (Minimum Efficiency Reporting Value) measures the filter's ability to trap air particles smaller than 1 micron, with indices ranging from 300 MPR (basic) to 2800 MPR (premium).
FPR ratings
range from four to ten, with ten being the most efficient. These filters are often used in hospitals and other large facilities where clean air is essential. An FPR four filter usually lasts about six months, while an FPR of six or more can last one to three years, depending on the degree of air pollution.Some filters on your website that have both an FPR and a MERV classification, and at least one with an FPR of 10, appear as equivalent to MERV-8 or MERV-13. The highest FPR rating available is 10, which is considered the most effective filter for trapping air particles smaller than 1 micron. This type of filter is often used in hospitals and other large facilities where clean air is critical. An FPR four filter usually lasts about six months, while an FPR of six or more can last one to three years, depending on the degree of air pollution. The higher the FPR rating, the better the filter will be at trapping small particles. This means that a filter with an FPR rating of 10 will be more effective at trapping particles than a filter with an FPR rating of four.
Additionally, filters with higher FPR ratings tend to last longer than those with lower ratings. When selecting an air filter for your home or business, it's important to consider both the MPR and FPR ratings. The MPR rating will tell you how effective the filter is at trapping small particles, while the FPR rating will tell you how efficient it is at doing so. By taking both ratings into account, you can ensure that you're getting the best possible air filtration system for your needs.
