Why does the 3M packaging from Amazon fail to include the MERV rating? (question to the vendors who are selling these)

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.

Mine say "FULFILLMENT BY AMAZON Amazon warehousedeals" in which case I think it's a bit more reliable than "just a 3rd party vendor". I've had success with them, but I haven't bought too many times from them. I think J. Bevier's response is right *if* it says that ("Amazon warehousedeals" etc.)

i believe it is just a naming issue (different sellers on Amazon labeled them differently). They are equivalent products.

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 bags shown are indeed made by 3m. What was shipped to me was panasonic bags. Bait and switched by GoVacuum.

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.

I had the same issue. They sold me the smaller version for the same price as the big one. My feelings are they are fraud in by advertising the big one. Amazon reimbursed me $20, because I ddidn't want my sweet daughters to have to package them back up and ship them back. I believe the seller is at fault.

Thanks so much for your response! I even chatted with 3M customer service and he told me he couldn't find it.

Thanks for posting this thread, Atticus. I recently went through the same scenario with customer service on this very item. I just bought an industrial strength paper shredder (which was huge!) and it was covered under Prime. So your point is very valid in spite of what the other posters are saying. Mike L: I just ordered these speakers in spite of the extra shipping and free shipping was not offered even at the standard selection. Standard: $23.65, 2 day $44.82, 1-day $83.65. I agree Prime is usually awesome, but don't quite understand what makes one item 3.99 for overnight ship and another $83.65. Jeeeeeeeeeez. (btw, industrial paper shredder was larger dimension box and heavier than this item.) Thanks for posting this thread, Atticus.

In fact, whoever is selling this cable as a 3M(tm) is committing a plain fraud (not just false advertisement), since the 3M(tm) is a proprietary connector, so the cables where only manufactured by 3M(tm). They are selling it as a "3m" (three meters) cable. Watch out for this flagrant fraud!

I always try to buy stuff like this through amazon, but I've also received it from a couple of different sellers.... its always been the same, grey plastic, white gauze and "apparently" official KX plastic wrap and paper label. I know some have reported fake ones.... if so, report to Amazon, complain and return.... yes, its a pain when annoying people do bait and switch, but still a "current" fact of life unfortunately.

That is a great question! I've ordered this item 5 times from third party vendors and received the OLDER version all 5 times! I've contacted Amazon a few times and informed them of the incorrect listing. No one seems to care to fix the problem at Amazon. Good luck!

I have no idea. There is no information on the package, which is surprising. I was wondering myself...Maybe we should write the seller/distributor and ask this question?

Why wouldn't you fix the listing. Seems like false advertising to me. Amazon should look into this!!!

Even i got in a whitebox with scratches on the product, why is amazon fooling everyone ? Anyways I am returning mainly because it was not fitting and keeps getting lose. But i am shocked to see others too complain .. is amazon trying to slip in bulk as retail ? Come on be true atleast, the box has a sticker which says "retail package" , how can a white box be retail ?

I just ordered these myself yesterday from Amazon (not a 3rd party) and hopefully I will not receive a fake pair. Did you order yours directly from Amazon and were there any visable signs on the packaging that would help me identify mine as fakes, before i open and remove the headphones from the package? The Sennheiser website has a description of the authentic packaging for comparrison. I also contacted Amazon to see if this problem can be addressed, hopefully before they ship my order. I look forward to reading any future posts to see how Amazon handles this.

It's a possible packaging issue. If you clearly ordered a 2-pack, we suggest you contact Amazon about this concern.
