3M Aqua-Pure Under-Sink Full-Flow Drinking Water Filtration System (Model 3MFF100)

E. MoisaE. Moisa: To ensure successful installation, use brass fittings (refer to the pictures) by attaching an adapter to each end of the filter (both in and out). Additionally, employ two 3/8 in. Compression x 3/8 in. Compression x 20 in. Braided Polymer Dishwasher Supply Lines, each priced at just $5.75 (for both in and out). If necessary, include a coupling to extend an existing 3/8 line. For a secure seal, apply plumber's tape around the brass fittings, wrapping it twice.

I recently implemented this setup for my kitchen sink, experiencing a significant improvement in water quality. Impressed, I added another filter under the bathroom sink a day later. The installation is straightforward, with more time likely spent at the hardware store searching for fittings and supply lines than on the actual setup. Additionally, note that the filter is substantial (about the size of a small oxygen tank and built like one), requiring about 17 inches of clearance. It stands independently, eliminating the need for mounting - I left both standing on their own. I hope this information aids in your decision-making process.

richard gagnon: good seller

JAI: I'm pregnant and we just bought a new home, built in 1904. The water service line is very old (likely original) and looked like a lead pipe lo and behold, our water tested over EPA limit for lead. Any lead is too much, but its testing at levels 14-18 (EPA limit is 15). Since the home is so old we decided against a whole house filter since there may be old parts elsewhere as well, and instead had this installed under the kitchen sink where we get all of our cooking and most of our drinking water. Since then, we had the water retested (available for free through NYC, check out 311 if in the area) and water is testing for 0 lead. Tastes fantastic also!

Obviously at some point we'll have to replace the line, but that's just not in our budget right now. I'll buy more of these for our other sinks, and replace the filters yearly. Its a small price for piece of mind without having to buy all bottled water (even more expensive and so much waste!) Lead only absorbs through ingestion or inhalation, not through the skin, so we are not concerned with shower or tub water.

M. Gilles Tissier: Expensive but a great product

marcus: After I bought it, I saw a message saying that this product needs to prepare some other tools to install it. Then I saw that the cover image was really the case.
I immediately asked the online customer about this situation. I repeatedly ask if additional tools are required to install? I ask, please let me know if you need pre-prepared tools. I can prepare in advance. I asked many times during the process. And the message said that tools and parts need to be prepared in advance. The customer service staff all told me that all the needed tools are in the package.
I love 3M. Have confidence in 3M's products. First instructions, and finally I successfully installed.
When I received the goods, I knew I had been deceived. I promised a friend to install it today and finish it today, but honestly, it's really not easy for a layman. I just finished installing it after I received it. I read the manual, but it's a little hard to understand. I took the manual to the homedepot and bought the tools and parts I needed one by one. Finally, watch the installation tutorial repeatedly on youtube and then complete the installation. It took half a day.
I feel angry and...

Flavio CostaFlavio Costa: Easy to install, but not so easy to understand what you need if you are a plumbing dummy like myself. Following the advice on other reviews, I ignored the included instructions on how to install it using plastic tubing. This is what I needed to have / to buy from a home renovation store to connect the filter to my kitchen faucet:
* Wrench
* Power drill or screwdriver
* Pen or permanent marker
* PTFE tape
* Compression adapter 3/8" OD x 3/8" MIP, two of them
* Braided stainless steel connector, 3/8"

First step is to close the valve from the cold water supply and open the faucet to relieve the pressure (to make sure the pipes are empty). You may then use the wrench to disconnect the flex connector from the faucet to the water supply.

Next step is to prepare the filter head assembly. Take the compression adapters, wrap the threads on the Male Iron Pipe (i.e. MIP) end with the PTFE tape to prevent leaks, and then screw the adapters on both ends of the filter head. The result is in the first picture.
Tips: The compression adapter must always be "3/8 MIP" at one end, as this is the dimension that screws properly into the filter head. The other end...

Jim: The filter head does not come with the Push-In Fittings at both end (inlet and outlet) and therefore you have to purchase the 2 fittings from https://www.amazon.com/John-Guest-Speedfit-PP011223W-Connector/dp/B003YKF17U.

KevinKevin: Got tired of Sparklettes overcharging and refusal to cancel but I think I finally shook 'em. I looked at the ANSI ratings and this one is ANSI 42 and 53 . Easy to Google search and read to your hearts content.

For the real test I filled two glasses . I posted a picture of The Aqua Pure on the left and Camarillo tap water on the right. I used swimming pool test strips . I also asked my teenager with good eyes to look at and taste the samples . He chose the 3M over the tap. The test strips show an approximate range by color change on the tiny squares located on the strip. The second and third squares are for chlorine . Green equals chlorine . The filter removed the chlorine . The 4th square ,the red one is PH level. I'm not sure if its possible but the sample on the left ,the filter sample, seems to show a higher PH level . It also seems a higher alkalinity on the filtered water from the test strip indication.

The pressure is easily 2.5 gallons per minute . I hooked up a dedicated faucet just for the filtered water and its very fast filling the coffee pot. This model claims one can hook it up straight to the kitchen sink but we chose to separate the feeds. No leaks at...

EdSEdS: Excellent water filter. The filtered water tastes just like bottled water. I can say this because after installation we did a blind taste-test. My wife only drinks bottled water because she hates the taste of tap water, and she thought the water from the filter was the bottled water. Now we don't need to buy bottled water anymore. The filter is NSF certified so performance and specifications can be trusted. As expected, water flow from the sink faucet was reduced a bit since water is now going thru a filter, but it was not reduced significantly from 1.7 to 1.4 gal/min. The water flow is fine. The replacement filter cartridge uses a 1/4-turn quick-connect mechanism so it will be easy to replace in 1 yr (or 6,000 Gal).

IMPORTANT INSTALLATION GUIDANCE: The filter is very easy to install. However, DO NOT install it as shown in the Installation Instructions that come with the filter or the 3M video that is found online. They both show Polyethylene Tube (i.e. Plastic Tube) being used to make the water connections, and we initially installed it that way but learned that there are several reasons not to use the tubing:
1) The main reason not to use the plastic tubing is the risk...
