When it comes to air filtration, there are two main classifications that you should be aware of: MERV and FPR. While they may sound similar, they are actually quite different. In this article, we'll explain the difference between the two ratings and how they can help you choose the right air filter for your home. MERV stands for Minimum Efficiency Reporting Value and is a rating system used to measure the effectiveness of air filters.
It is based on the size of particles that the filter can capture, with higher numbers indicating a higher level of filtration. For example, a MERV 8 filter will capture 90% of particles from the air, while a MERV 11 filter can remove around 95%, and a MERV 13 filter can block approximately 98%. On the other hand, FPR stands for Filter Performance Rating and is a rating system used to measure the pressure drop and dust-holding capacity of air filters. For example, an FPR 4 filter will capture 90% of particles from the air, while an FPR 5 filter can remove around 95%, and an FPR 6 filter can block approximately 98%.
The main difference between MERV and FPR ratings is that MERV ratings measure the effectiveness of air filters while FPR ratings measure both the pressure drop and dust-holding capacity. This means that while a MERV 8 filter may be effective at trapping small particles, it may not be as effective at reducing pressure drop as an FPR 4 filter. When it comes to choosing an air filter for your home, it's important to consider both MERV and FPR ratings. If you want to ensure that your indoor air quality is flawless, you'll want to try to find a MERV 20 filter but you'll most likely have to settle for a MERV 13.
On the other hand, if you want to reduce pressure drop without sacrificing too much on filtration, you'll want to look for an FPR 8 or 9 filter. In conclusion, MERV and FPR ratings are two different classification systems used to measure the effectiveness of air filters. While MERV ratings measure the effectiveness of air filters, FPR ratings measure both the pressure drop and dust-holding capacity. When choosing an air filter for your home, it's important to consider both ratings in order to get the best results.
