What is the MERV Rating?
1050337
It is 11. I can say they are good. The EPA has a page dedicated to home air filters here http://www.epa.gov/iaq/pubs/residair.html#Will-Air-Cleaning-Reduce-Health-Effects

Looking for them at a local store, the ratings HAVE changed to only about four ratings. They no longer use the 1000, 2000 "performance ratings" They use only 2 (I think 2) 4, 7, 9 and 11 "FPR." The 1000 that I bought last year appears to be consistent with (pictures what it should filter out) a 7 (seven) rating, not 11. The 9 or 11 might be the old 2000 rating, but not the 1000 pictured in this listing. The seller needs to UPDATE the picture as I would be/am hesitant to purchase without knowing for sure which filter rating "FPR" number it really is. Really have liked the ones I've used, though I change them monthly. Helps keep inside furnace clean. Looking for them at a local store, the ratings HAVE changed to only about four ratings.

I don't see a "MERV". It says the rating is "1000 MPR" (micro performance rating). I believe when I purchased these filters I had googled the rating and read that the rating system had changed. Can't quite remember the particulars. Try googling? BTW - I swear my husband's breathing has improved since I started using these filters. He suffers from COPD.

There is tradeoff between how much particles get filtered out and how much air gets through to your system. As much as it sound good to have EVERYTHING filtered out, that isn't necessary, and may strain your air system. A range of 7 to 12 is really good for a residence. More than that is for science labs, hospitals, etc. But whether to choose 7 (less filtration, more air through) or 12 (finer filtration), may depend on the age, condition and efficiency of your AC/heating system. An older system might be stressed by trying to pull air through a finer filter, or cost more to run the system because it has to work harder.

MERV rating is a fabricated numbering system created by Filtrete. The higher the number the more particles it can remove from the air. This numbering system, however, is not used by any other filter manufacturing company and therefor is biased.

One more thing on the higher filtration filters. As other comments DEPENDING upon your furnace/AC, they MAY BE took thick for adequate air flow. My installer/yearly check up company said ONLY use LOWER filtration for times when the Air Conditioner is used as they CAN cause freeze up. On the high efficiency newer furnaces, they can do fine with higher FPR rating. So I use 4 thinner rating in the summer and the 7 in the winter.

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.

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

I'm not sure what the MERV rating is, but I can tell you that these filters have been great.

Our MERV 13 media is not electrostatically charged. Normal filter media mostly captures dust particles by physically blocking the dust from passing through the media. Electrostatic media mostly captures dust particles by electrostatically attracting the particles to the media.

The MERV number is a rating system. Minimum efficiency report value (MERV). Basically, the higher the MERV rating the greater percentage of particles captured. MERV 11 as this filter is, is for Superior Residential applications, meaning it's the higher end of the residential markets. The next bump up is MERV 13 which is typically used in a hospital type setting.

the standard rating is 5,options are from 2,10,20,40,70,and100. I hope this helps.

I would like to know the same thing. I am assuming below 4.5, but I'm not sure...

Dear D. Lester: No, no MERV rating anywhere on the item nor on the packaging/box. Said filter is a basic, fiberglass-type of filter. BTW, I purchased one case of these filters, there was suppose to be 12 in the case (case count of 12), but the box, undamaged and unopened, only had 11 filters in it. Good luck.

Hi Karen: The Merv 16 is intended for standard filter openings measuring 16inX25inX5in. I just measured what you have referred to as the height of the Merv 16. It measures around 4-3/8 in. An opening of 4-3/4 in would be around 3/8 of an inch larger than the Merv 16. As such, the Merv 16 should fit the filter opening of your AC. I would try to install the filter carefully because you would not have too much space to play with. Hope this helps.

None that we can do but on internet you can find test ratings. Meso rated 100-110 %. Why I chose it. Can see the difference over the 1st one I bought which tested 50%.

Not sure of the R rating but it did make a difference in our electric bill since we have had it.

Thanks for your question, According to the product details, this listing is for Merv 11 media. I hope this helps!

Merv 12 and Merv 11 is just the rating on the furnace filter. The higher the number, the more particles the filter will take out of the air. The problem is that if you do not replace a Merv 12 more frequently (3-6 months depending on your home's air quality) it may restrict the air flow to the furnace and can possibly damage the furnace. I usually stick with the Merv 11 because I find it is the happy medium - takes almost everything out of the air but does not restrict the air flow. Hope this helps

My guess is 7 or 8 based on the arrestance valueSource: http://www.mechreps.com/PDF/Merv_Rating_Chart.pdf
