What Is Mpr Air Filter
MERV vs FPR vs MPR air filter ratings, which is improve? What's the departure between these air filter ratings? Conversations effectually air filter ratings tend to create more of defoliation and less of clarity.
I put together this resources to clear the air. Hopefully, this post clarifies the difference for you and helps you lot make informed air filter purchase decisions.
MERV vs FPR vs MPR Filter Ratings
A MERV rating measures a filter media's ability to remove particles in the 0.3-ten micrometer range while MPR measures the ability to capture particles smaller than 1 micrometer. Actually, the MPR scale focuses on particle sizes that the MERV scale "ignores" until MERV 10.
Equally for the FPR rating, it'southward a unproblematic system used by Home Depot to rate various products promoted past different manufacturers such equally Honeywell. At that place'south no reliable way to covert betwixt these filter rating systems. Even so, each rating system is reliable enough.
What is a MERV Air Filter Rating?
A MERV rating is a numeric value ranging between ane and twenty and describes a filter's ability to remove air pollutants of a item size distribution. The American Society of Heating, Refrigeration, and Air Conditioning Engineers developed this filter performance rating system in 1987. This number represents the worst-case air filtration performance of a filter when removing air contaminants in a detail size distribution.
For example, if an air filter has a stated MERV rating of between 1 and four, it tin can remove pollen, dust mites, cloth fibers, rug fibers, and sanding dust downwards to the 10-micron particle size.
In this resources, I explicate in everyday language the MERV rating meaning if you lot're interested. I've also included a MERV rating chart so you can learn what air filters in a given MERV range tin can exercise and what they can't do.
What is a Skilful MERV Rating?
All MERV ratings are proficient. That said, the higher the MERV rating, the more granular the air filtration. While higher-rated filters are highly efficient at removing the finest particles, they restrict airflow immensely. As a result, they aren't as free energy-saving every bit lower-MERV options.
Lower-MERV air filters such as MERV 1 through 4 aren't bully at capturing extremely tiny filters. However, these filters are proficient enough at removing larger particulates. And they practise the chore without overly limiting airflow.
For near households, a MERV rating of 8-10 should be proficient enough. The best rating is MERV 13 provided that your HVAC organization can operate without problems when you install this high-form filter. Unfortunately, MERV 13 filters have been found to over-strain certain HVAC systems.
What is an FPR Air Filter Rating?
FPR is an abbreviation for Filter Performance Rating. Like MERV, the FPR rating describes a filter media'south air cleaning ability. But unlike the MERV rating which starts at 1 and ends at 20, the FPR scale ranges from 4 to 10. Domicile Depot adult this rating, and while information technology'due south different than MERV, information technology'south pretty like to it.
Both MERV and FPR apply numerical values to communicate filter effectiveness. Nonetheless, the FPR ratings relies represent to a ane of iv colors in a color-coded system. These colors are green, red, purple, and black.
FPR Filter Rating Nautical chart
| FPR Filter Rating | Colour Code Identifying the Rating | Meaning of Color Code | What'southward Removed? |
| 4 to v | Green | Good | Big particles including dust, lint, grit mites,pet dander, and pollen |
| 6 to seven | Red | Better | Small particles and larger particles ranging from grit, dust mites, mold spores, pet dander, pollen, and bacteria. |
| eight to ix | Purple/Violet | All-time | Large particles and small particles equally captured by half dozen-7-rated filters but likewise filter out fume, smog, viruses, and microscopic allergens |
| 10 | Black | Premium | Everything removed by filters rated 10 on the FPR scale, simply too filter out odors |
What is a Good FPR Rating?
Any filter with a rating of 4-5 on the FPR scale should be good plenty for removing common household air pollutants including dust, lint, dust mites, pet dander, and pollen.
What is an MPR Air Filter Rating?
MPR stands for Microparticle Performance Rating. Developed by 3M, the MPR filter rating measures the power of an filter to remove sub-micron particulate matter. The MPR rating scale uses much college values compared to MERV. It starts from 300 to 2200 versus 1 to 20 for MERV.
The higher the MPR value, the better the filter media is at capturing indoor air contaminants smaller than one micron in bore. This rating organisation measures a filter'southward effectiveness at tackling particles in the 0.3-1-micron range. It really offers more than comprehensive filtration compared to MERV rating. Here's a startling fact: MERV doesn't showtime measuring sub-micron particulates until MERV x!
Is an MPR Rating of 300 Good Enough?
An MPR value of 300 is the lowest MPR rating a filter tin take. Filters made to this standard remove household dust and lint well and nothing much besides.
A rating of 300 MPR is similar to a MERV rating of 5 and FPR of less than 4. Obviously, information technology'due south a pretty lame rating and won't do enough for a person who reacts to allergens such mold spores and pollen. An MPR of 1000+ is where serious filtration starts happening.

What is a Skilful MPR Rating?
If it's just dust, a depression MPR rating of 300 should suffice. Just if you're looking to capture a whole bunch of contaminants ranging from dust, mold spores, pollen, pet dander, smoke, bacteria, viruses, and fifty-fifty auto exhaust fume particles, you need the best-rated filter.
Yous need a filter with a rating of not less than 2200. With such a filter, you shouldn't worry well-nigh most PM2.5 particles and PM10 particulates.
MERVvs FPR vs MPR Ratings Chart
These three filter ratings are somewhat different. But they're similar in that they measure the aforementioned miracle, a filter'south ability to reduce indoor air pollution.
Unfortunately, there's no fashion to accurately catechumen any of the ratings to the other two. That said, the nautical chart beneath should assist y'all estimate how each rating relates to the other two. *This isn't an air filter rating conversion chart.
| FPR Filter Rating | MERV Rating | MPR Rating |
| <4 | v | ~300 |
| 4 to five | 6 to 8 | ~600 |
| 6 to 7 | 8 to 11 | ~600 to ~chiliad |
| 8 to 9 | 11 | ~thousand |
| 12 | ~1500 | |
| 10 | xiii | ~1900 |

*Treat the nautical chart higher up as indicative rather than definitive.
Wrapping Up on HVAC Filter Ratings
While the MERV, MPR, and FPR ratings aren't exactly the same thing, they measure the same quality: a filter's capacity to capture contaminants.
Each of them was adult by trustworthy and knowledgeable entities. And all are reliable as far as comparing the effectiveness of air filters.
