What is a MERV 8 Filter Equivalent To?

MERV 8 filters are comparable to an MPR of 600 and an FPR of 5.MERV 10 is equivalent to an MPR of 1000 and an FPR of 6, while MERV 11 is equal to an FPR of 7.MERV 12 is equal to an MPR of 1900 and an FPR of 8 or 9.It's important to note that different MERV 8 filters don't work the same across all particle sizes. Pleated filters have a much higher efficiency on medium and small particles than polyester pads or annular panels. The ASHRAE 52.2 test method is designed to measure the fractional efficiency of a filter by particle size. If you have pets or someone in your home has serious allergy problems, you can consider a higher MERV value, between 8 and 10. The higher the rating (for MERV, FPR and MPR), the smaller the air and dust particles your home air conditioner filter can capture. A MERV 8 air filter is effective at trapping most indoor particles that could weaken people with asthma and allergies, or even cause long-term respiratory issues. For a rough comparison of the different MERV levels offered by Filterbuy with those of the MPR and the FPR, see the table below.

MPR stands for Microparticle Performance Rating and is a patented air filter classification system created by 3M to make its air filters appear to have a unique rating and filtration capacity. Filters with a MERV 13-16 value are the most restrictive and can trap the smallest particles, such as bacteria, tobacco smoke and burnt wood. Select an air filter based on these contaminants and then follow the manufacturer's recommendations for changing or repairing the filter. If you're using a higher MERV rating that traps more particles, you may need to change the filter more often. A MERV 9 will capture less than 50% of particles between 1 and 3 microns in size, while a MERV 10 will stop up to 64%, a MERV 11 will trap up to 79%, and a MERV 12 is capable of capturing up to 89%.When it comes to choosing an air filter for your home, it's important to understand what each rating means so you can make an informed decision. The higher the rating, the more efficient the filter will be at trapping airborne particles.

However, it's also important to consider how often you'll need to replace your filter based on its rating. Higher ratings mean more frequent replacements. If you're looking for an air filter that will provide maximum protection against airborne particles, then you should consider a filter with a high MERV rating. However, if you're looking for something that will last longer before needing replacement, then you should opt for a lower rating. Ultimately, it's up to you to decide which option is best for your home.
