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

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.

Here is the information we have from 3M, the Filtrete 1900 Ultimate Allergen Filter: MERV Rating :12 with a Microparticle Performance Rating: MPR:1900.

I could not find that type rating on the info data. We bought it based on some our friends recommendations. We have found it to be satisfactory if one follows the instructions provided.

I was told by the HVAC guy that you want to use a lower merv in the summer with air conditioning, to facilitate cool air movement; and a higher merv in winter, to capture dust and allergens from recycled indoor air. I use a 6 average merv in summer, and 10 or higher in winter.

I believe it's rated; however, anyone I know who's purchased one of these things, the bottom leaks right out of the box. do not buy from amazon, they are of no help when it leaks. who's going to send it back once put together? I'd go to a sports store, regardless of price, fill up the bottom before you do anything--even if you have to empty it to put together

Dear Doyle - same problem here - generic 3M packaging with no clue as to MPR rating. This could be significant as the lowest rated MPR may be 1/2 of the price of the highest rated filter.

Sorry, Can't answer. Bought item to install and then sold house so no experience. Mfr says it is very low but no recallof value - or writing a review =G=

The box says MERK 8 but there is nothing written on the filters except the size.

Hey Jonathan this unit has not been rated. The unit is seal pretty good but lets face it this is not how this unit works. You are looking for a very expensive unit like a IQ air 1,200.00 and up this is a small company and did not have unit rated. Also the filters are great but they will never clean all the air in a room or more with out the ionization. Ionization does most of the work and at a lot lower cost call me Lou Lombardi toll free we can talk 800-868-5534.

The difference is what is filtered the higher the Merv number the small the particles that will be filtered. You can Google Merv to get a more detail definition.

I ordered the Merv11 and it was the correct size and labeled Merv11 on the filter.

I'm sorry, I don't know the answer, but you can ask at Mercola.com . He is very knowledgeable.

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."

I'm not sure what it is rated, but it's def a light action rod. I love mine, perfect to pack into a bag and take anywhere there are fish!

The 210 has a MERV rating of 210 and the 213 has a MERV rating of 213. The higher the rating the better it will filter small particles.
