is a merv rating of 8 better than an 11
1742741
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 did a search on the internet and found this link: http://www.filters4life.com/What-is-MERV-rating-s/4961.htm . It give information from 1-16 and gives a color guide of red for the lowest, yellow, light green and darker green for the best. This indicates that 11-16 is in the darker green, with 16 cutting 95% of the dust and allergen particals. I'm glad you ask because that give me a better ideas of what I'll want the next time I purchase.

Yes and No.The higher the Merv rating, the more strain you will put on your furnace/blower. The more denser (Higher Merv rating) the filter, the more your blower motor will have to work. Of course, you will pull out more particles/dust/pollen etc out of the air, with a higher Merv rating. I have a variable speed blower motor/fan, so my Hvac technician can adjust my blower/fan speed. For my house, approx. 1600 sq ft, I found the Filtrate 1000 (Approx Merv rating of 11) to be ideal, with my two cats. I also buy charcoal pre filters here on Amazon and use them with my filter. They also tend to pick up a lot of stuff out of the air. I then vacume both the filter and pre filter (with a Hepa vacume cleaner) at least twice a month. I then change my furnace filter every 4 to 6 weeks-even though the filters would be good for at least 90 days. This may be considered excessive but my Hvac tech states my coils are always clean and the house is cool/warm when I want it. Next time your Hvac tech is at your house and servicing your system, ask him/her what they recommend.

Sorry, I can't help with this one. However, after researching the MERV ratings, I can tell you that a MERV 16 is delivering "Clean Room" quality air.

MERV Rating is a good way to help judge the effectiveness of the filter. MERV means Minimum Efficiency Reporting Value which was developed by the American Society of Heating, Refrigeration and Air Conditioner Engineers - ASHRAE. MERV values vary from 1 to 16. The higher the MERV value is the value the more efficient the filter will be in trapping airborne particles. Another consideration is air flow through the your HVAC system. Leaving a dirty air filter in place or using a filter that is too restrictive may result in low air flow and possibly cause the system to malfunction.

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.Sincerely,Bill Bochynski626-524-4392

The Filtrete Ultimate Allergen 1900 MPR rating, which is the same as a Merv 13 rating. Filtrete uses the MPR rating instead of a Merv rating, that is why we do not have a Merv rating listed.

Merv 1900. This is not listed on the packaging, but is listed on Amazon under technical details.

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."

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.

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 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 would say an 8. It is spicy but not very very spicy. Its nacho. So if you had nachos at a game or anything I'd compare it to that.

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."

I got 7.8. just keep in mind that the total score is equivalent to the least performing part

The MERV rating is 11. The MPR rating is 1100. An MPR range of 1000 to 1500 is within the 11 MERV rating. I found this information on the Filtrete website.

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.

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?
