What Are MPR Ratings?

So, what are MPR filters anyway? The most basic definition is that they keep unwanted substances from getting indoors.

The MPR rating for your filters tells you what size of particles it’s able to capture. The higher the number, the lower the size of molecules it can keep from entering your environment.

While buying a filter with the largest number may sound like a good idea, it can also be unnecessary. You can start prioritizing what types of MPR filters may work for you by understanding the following categories.

MRP 300

A Microparticle Performance Rating of 300 represents a basic level of protection for your home. This filter will keep out larger objects like dust or mites, but it won’t stop bacteria.

As with other types of air filters, these come in different sizes to cater to your system. A popular option installed in homes is the 16x16x1 size.

MPR 600

An MPR 600 filter offers more consistent protection from pollen, dust, or mold spores. However, it does not stop pet dander, smoke, or fine dust particles.

If you live in an area where these factors are concerns, consider moving up at least one more step. These types of air filters may work fine if everyone in your home is healthy and without respiratory issues.

MPR 1000 – 1200

An MPR of 1000 to 1200 will take care of almost anything a homeowner may worry about entering their property. Smoke, dander, and even a long list of allergens can’t penetrate its construction.

MPR 1500 – 1900

Having filters with an MPR of 1500 to 1900 represents the highest level of protection.

With this in your HVAC system, you can keep anything between 3 and 10 microns. Viruses, bacteria, and even small particles that carry odors get trapped. If you have a family member with asthma or other respiratory issues, this may be a godsend that you don’t want to live without in the future.
