Aqua-Pure Under Sink Replacement Water Filter Cartridge 3M FF101

Full disclosure - I worked for 3M Company who makes this product for 37 years, which makes me biased. But that also makes me knowledgeable. In this case this filter will attach to the cold water line under your sink and provide full flow (2.5 gpm) filtered water for drinking and cooking. This is SO much better than installing a “shepherds crook” faucet on top of your counter that filters well but takes forever to even fill a glass. You can also use the same water line to feed your ice maker. It removes all the bad stuff you would worry about and makes the water taste great too. I believe the life of the filter is about 10,000 gallons or so. I replace mine every year. The replacement is very easy - a twist off/twist on process. Have recommended to all my friends and everyone that tries it loves it. Replacement cartridges are expensive but the ease and utility makes it worthwhile for us.

Easy to install. Known (national) brand.

We've been traveling nearly full time for over two years and have found these filters give us far better drinking water than bottled water, which we used to buy in jugs or cases. Once set up it's so convenient. Pricey, but they last about a year, sometimes more. I run through a pre-filter first to pull sediment. A 3M tech tipped me on that and it extends the filter life dramatically while pulling harmful sediment out that can rapidly clog the 3M filter.

Under kitchen sink Water purifier canister. Last a long time. We eventually start to notice a slowdown in pressure and then we know it’s time to change and in some ways makes us feel reassured that it does work. Always arrives quickly. We are worried about the water as well as the old pipes that run from the city water line up to our top floor apt. Soooo old and rusty. This gives us a little peace of mind.

like most people, i had previously bought this filter with no issues. then i purchased again and the replacement filter i received had metal shavings and gooey stuff on the top, thinking this was contaminated somehow or possibly a used filter that had been sent to me as new, i returned and reordered from a different vendor. the new one came the same way, it was sealed in plastic, brand new and when i took the cap off, same thing gold metal shavings and goo. so i called 3M. I spoke with one of their water purification representatives, and he shared that, the metal shavings are particulate that is part of the interior of the filter, and that the goo is food grade silicon gel. Both are fine to be on the filter and just need to be wiped off before installation. he used the analogy of over filling a fountain soda and the coke spills out of the cup onto the outside. so they fill these plastic bottles essentially with the gold stuff and it spilled over the top. he did concede that this is an issue at the factory that they are trying to address it, but in the mean time the way the filters are, are ok and not contaminated. I am ok with that, but at $200 a replacement it seems perhaps they could have better quality control. Also my filter lasts nowhere near a year, at best i get 6 months, so that is pretty expensive to replace 2x a year. but it does do an excellent job, but i am considering a whole house filter instead of these expensive filters.

I love the quality of the product, it is impeccable.

Very easy to install. Water clarity and taste is excellent. And it lasts at least a year in service

It can last up to 1 year, or more depending on the use, I intalled in the sink faucet (cold water).

I love it.

On time delivery

Fast delivery and it came with the original packaging.

Works well in RV to remove taste of chlorine in drinking water at RV parks.

I used to have the smaller 3M filter and recently upgraded to this one. Which is huge, by the way! The water just tastes "pure", for lack of a better word. Almost similar to distilled water, but not as bitter. Bought one for the kitchen and one for the bathroom. ...now if only they were a little cheaper!
