How do I know this really MPR=1900? No info on packaging (other than 3M filtrate)

Regarding the rating on this filter, if you click on the photo for this ad, you should see an enlargement of the picture. The 1900 mpr rating should become visible.

Here is the information we have from 3M, the Filtrete 1900 Ultimate Allergen Filter: MERV Rating :12 with a Microparticle Performance Rating: MPR:1900.

It was not my listing, rather a package I bought from Amazon. I use a Mont Blanc and much prefer original German cartridges. I once bought cheaper substitutes which did not work well at all. I did not send the package photo. It was from the Amazon site.

There is a mark for each Mil example: .5ml, 1ml, 2ml and 3ml are clearly shown. No guessing if you need only need a mil or 2

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.

As I noted in my review, all of the filters that I rec'd are marked 228 micron. It is my understanding that the "assorted" means that you could receive anything in the 90-190 micron range (even tho I rec'd 228 micron!); "assorted" does not apparently mean that you will receive an assortment of sizes.

I suggest you contact MPS Direct...they are the seller and should be able to tell you.

There are too many sellers to get a straight answer. It used to be nice when Amazon would sell these directly. You could be sure it was a genuine new item. At this price from a third party seller, you can be pretty sure it is a remanufactured cartridge.

I suggest contacting the company for clarification. The number is on the bottle and you can see it in the picture.

Sediment filters don't have GPD ratings, you're thinking of the membrane - and that's not included in this kit. The rating for the sediment filter would be in microns (the size of the particles that it will filter), and in this case it is 5 microns.

Well, the packet of ph substance says "make up 250 ml" on the one I have. I think that's what I did.... But it's been awhile.

A company representative informed me that it filters 100% of that particles. Their website says "99%" of particles. Another company representative said that it was "under 1 micron."

There should be some more numbers after the 5kcp39eg on the label. If you provide those we can cross reference.

The lable does not specify. I suggest calling MT or refer to their website.

Sorry can't really answer this accurately because they sent me the wrong filter.

Sorry I do not know. I only have 225pgbk with me and even on that packaging I did not see any ml specified.
