Do these have a MERV rating? If so, what is it?

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.

For the use I give them, airplane trips 2-3 times a year, they appear to hold up well. As for daily commuter use, maybe not so much. But having had no experience with the "pricy-er" brands I can't make a comparison. They do however appear to be quality construction. Sorry I couldn't be of more help.

These are grade A, I'm reasonably sure, although Amazon doesn't provide enough information. Grade B are the "Value Line" that are advertised as 50 year archival rather than 100 year archival. The gold ones are something else altogether, more for looks and mainly a gimmick if you ask me. There's a whole lot of misinformation in some of these comments. One guy say JVC is D grade. JVC = Taiyo Yuden!

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.

I bought them as a gift. I have not heard back there was anything wrong with them. There was a note enclosed with them on how to care for them. They have not rusted. Plus, the company was very sincere in wanting to make sure I was happy. If you bought something and was not pleased, I believe they would make it right for you. Sorry to not have more specifics for you.

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

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.

I don't really know what classifies "commercial grade" but these are comparable to the Food Saver brand bags. Hope that helps.

They are marine rated. Meaning they will survive in a wet environment. They are not waterproof per say. I have them in my motorcycle fairing. Not all that pleased with the sound so far. Looking at other speakers currently.

I don't know about their rating but that is exactly how I used them and have had absolutely no problem using them that way.

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

Yes they are marine rated. I use them in my Jeep with no top all summer long. Work pretty good. About to install a couple on my motorcycle fairing.

I do not believe these are fire rated, as I couldn't find any information on the Website or my manual.

Don't know. I'd contact Merrick directly. Our dog loves these but we only give her one or two a week. Takes her about 20-30 minutes to devour.

They are reliable if you get gold or platinum certified. The cheap ones, not so much
