What is the MERV Rating?

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.

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.

I always have and it's never seemed to be a problem. You can always check with the folks at mercola.com however if you want to confirm it.

Just received my latest order of Merrick BG#1. I order (2 of these about every 4-6 weeks to feed my 4 cats. Looking at the latest UPS label it states "24 LBS PREMIUM" that is for (20 11.1 LB bags. I am an amazon PRIME member so I don't know if this enters into it. My question is "does it matter"? as long as you received your order on time and in good condition. I would suggest that you look at the label on the next shipment(s). My shipment came from KY --> PA. Hope this helps. Jim L.

The UMF rating is something that vendors must pay for to show the standard of the product, similar to the certified organic labels we see often. It is an added level of quality control. This type is not a UMF rated product but the 10+ is a measurement of the peroxide activity levels that their labs have detected. It is a great product for the price and I would buy it again but be aware of the umf rating as some brands are charging a premium price for non- umf rated honey so be mindful of that when shopping for your honey.

no, it's same as from wv1 (but colors may be brighter)...merle is a wv3 repaint but same color scheme as the upcoming wv5 zombie merle (but w/out extra blood aps)..also the keys are from the carl fig. The keys replaced the squirrels that the original released Daryl had as an accessory...forgot to mention that before.

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!

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?

I have no idea about the CADR and MERV rating. I sent this over to my son in Afghanistan as the dust was so bad over there. He said it worked great and was easy to clean as well. So I'm just giving you second hand info but hope it helps. It made life more bearable for him.

I don't know what rating means in the content you are asking but it is a really nice heater works GREAT it gets hot if you turn it up too high I love my pool

Look for same MERV (Minimum Efficiency Rating Value) ratings. Regardless of capacity claims, this is an industry standard rating system that allows you to compare filters made by different manufacturers.

I did a search on the web for this model number, UA01DC-6, and found that its MPR rating is roughly equivalent to MERV 12, so I agree with others who have said MERV 12.

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.

It doesn't appear to carry a UMF or MGO rating and chances are it wouldn't qualify, i.e. it's probably less "active" than UMF 5+ or MGO 100. Much the same as the Wedderspoon honey, which also fails to show a UMF or MGO rating and instead shows "total activity" which doesn't mean much.

There is no way of knowing. This is bulk packaging and the rating is not indicated anywhere on the label. From the research I've done, my guess would be an "A" rating.

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.

Well, I haven't looked for actual test results for proof, but from the packaging on mine: "This filter's performance has been rated MERV 8 based on the minimum efficiency observed during the industry standard ASHRAE #52.2 test. The test is a determination of the filter's ability to trap particles in the air we breathe. These particles range in size from .3-10 microns in diameter. Residential filters typically are rated in the range of MERV 1-10. Higher ratings indicate more efficient filters."
