what is the Merv Rating and how do you convert 1550 MPR to a Merv rating?

I had this same question, and found this link: https://strivenindustries.zendesk.com/hc/en-us/articles/200372840-MERV-vs-MPR-rating Essentially, MPR of 1500 or over is MERV 12.

The MERV rating is a standards manufacturers use to compare the efficiency of filters. The higher the rating, the better the efficiency I picked the following information off another site "the following MERV ratings measure filtration efficiency of particles ranging from 0.3 microns and up. With more an more emphasis being placed on micro particles, 3M developed their MPR Micro Particle Rating to measure filtration of even smaller particles, down to .001. Some competitors are beginning to adopt the new standard that 3M developed but there is still predominant use of MERV. As a reference, the 3M Micro furnace filters have a MPR of 1000. Their rough equivalent MERV rating is 13-14. So while their is currently no sure equation way to convert MERV to MPR, if you use the approximate MERV rating of the Micro filter MPR rated at 1000, then the 4" filters MPR rated at 1550 would conceivably exceed MERV 18, which currently puts their filtration in line with the more expensive NordicPure furnace filters. Because 3M uses this different measuring scale and system, it's difficult to do a straight comparison."

While I am not sure the Filtrete Allergen Reduction Filter is exactly the same as the Filtrete filter shown in the following commercial website, the table shows a MERV of 11 for a MPR of 1500. All the products seem to be 1" rather than 4." I don't know if that affects the MERV. http://www.iallergy.com/filtrete-air-filter-comparison.phpThe bottom of this commercial website page also describes the relationship of MERV, MPR, and FPR ratings for AC and furnace filters:http://www.bestfilters.com/AC-Furnace-Filters_c_605.htmlBased on my reading of the table, a MERV of 11 seems consistent with MPR of 1550.

In general no. In order to use a Merv 12 to replace a Merv 11, you need to know if you system can handle the extra pressure drop caused by the higher efficiency Merv 12. My heat pump/ ventilation system cannot support the pressure drop of a Merv 12. Compressors operated above design limit will die sooner than normal. Consult with an above average HVAC company.

Patricia, I went back and looked at the "product description". It says 15-20 mmhg.

The current filter we are looking at is Merv 11. For higher Merv value, you probably need to look for Merv and FC100A through search engine. Thanks.

The MERV rating tells you the amount of dust and other contaminants the filter removes from the air. The ratings go from 0 to 20 with the higher number taking out a higher percentage. MERV 10 takes out about 50% of the dust

120-240 written on transformer. It's not a wall wart per se. It's an inline transformer FWIW.

Not sure but you could probably get a converter I would go to their web page

i I read the other answer after iI submitted my first answer. I totatally disagree. The msr is similar to 120 but msrx is completely different animal. I have all of them .I know

Dave,Don't know anything about "MERV levels" but the filter that came with my PM1200 works fine for me. I have to remove the standard filter weekly and "beat" out the dust but it is still working after 2 years.

The box and the filter have MERV 10 printed on them, so I assume it's MERV 10.

I was wondering the same thing- what is the MERV or MPR rating? I did a Google search on the web for a few of the part #'s (based on the sizes) listed on Amazon. From the search results, the info shown on the 3M website says that the part #'s are rated at MPR 1900.I searched for "Filtrete UA00DC-6" and "Filtrete UA01DC-6" seperately, which are the 16x20 and 16x25 sizes respectively. In the search results, there is a page that starts with "solutions.3m.com". Click on the link and there on the product page it says 1900 MPR.(I currently use the "High Performance Maximum Allergan Reduction Filter", which is 1900 MPR. The code printed on the outer top/bottom edge of the filter is "MA01DC-6") I was wondering the same thing- what is the MERV or MPR rating?

On my AWS scale [purchased from Amazon!] 1/2 tsp should give you a bit more than 1.5 gm.

Someone must know the rating, but that info is not here on Amazon's page or on the product label photos. 3M's own site doesn't even show this "Select Healthy Living" model name or its MERV rating. Not good when makers and sellers conceal information, and very untypical of 3M.
