Customers are mixed about the flow of the water filter. Some mention that it moves water through faster than the previous filter, and has a fast enough flow to allow the pressure-dependent sprayer. However, others say that the water flow is slower as expected with adding obstructions in the water.

"...Also the water pressure did not drop at all at the faucet which if you own a brita style you know how much you lose when you filter the water...." Read more

125 customers mention78 positive47 negative

Customers are mixed about the fit of the potable water filter. Some mention that it fits well under the sink without taking up too much space, while others say that it didn't fit. The provided connector would not fit their new faucet, and the filter is extremely large.

"...It didn't fail. Easy to install, fits nicely under the sink (a good reason to have the wife get all her chemicals out from the sink!)...." Read more

"...The provided connector would not fit my new (Watts) faucet...." Read more

"...Water taste is great (no taste really). Great for filling a big pot for pasta, it took forever with the old PUR system...." Read more

"...Luckily my faucet hoses were standard size do everything fit well...." Read more

Use it properly, it should work just as advertised!
5 Stars
Use it properly, it should work just as advertised!
I've just finished installing it, which was very easy. We had copper pipes coming from the under sink shutoff, which is not compatible, so a quick trip to the store and a $5 flexible hose later, I finished the installation in about 15 minutes. This is only on the cold line on our wet bar, and I drink 6-8 16oz glasses a day from it, fill a 12 cup coffee pot several times a week, as well as a couple ice cube trays.The instructions tell you to run the system for 5 minutes before initial use. Take this time to properly adjust the pressure of the shutoff valve so it's EXACTLY on what can come out of the spigot. Over-pressuring the system will eventually lead to failures and possible leaks! DO NOT TURN YOUR FAUCET PAST WHERE THE FLOW PRESSURE IS MAXED OUT!So after being thoroughly fed up with failing on-faucet filters and leaking refrigerator ones (the latter of which leaked behind the fridge, went into the basement, and destroyed an antique cabinet), having this unit at our wetbar fixed all of our issues.Realize that putting this on your kitchen sink will drastically lower the lifespan of the filters. This isn't meant for washing dishes, it's meant for your drinking water, filling pots and ice cube trays, etc.UPDATE: used for over 1 year with no issues. Only JUST ordering my 2nd replacement filter, but the original is still working, although pressure is reducing gradually. Your mileage will vary depending on your local water and how often it's utilized. Our water comes out at only ~.80 according to my Zero Water's reader, so this is well worth the price to me.

Reviewed in Canada on October 18, 2018
Ok first off: If you are looking for an under-counter reverse osmosis system with full flow for less than $100 bucks, then this is not for you.
However: If you are looking for an inexpensive filter system that gets rid of the taste of chlorine on the cold water line in. your kitchen, this may work for you.

Installation: It was easy to install in-line with the supplies in the box and the existing line going to the cold water feed. It mounts easily under the cabinet. The filter itself does not need priming or flushing prior to installation or use. It was a straight forward job to get it installed and can be accomplished by anyone who has changed a feed line on a tap or bathroom fixture.

Performance: Well its almost like a Brita filter for the cold water line... It does restrict the cold water flow a bit, but not a lot and that was to be expected. I just turned down the hot water feed to match the pressure and they are still balanced. Even while operating on cold water only, the spray feature on our tap works, so there is still enough pressure.

Taste: Its as clean as the water coming off the fridge. Not quite reverse osmosis level, but a noticeable enough difference in cleanliness. Our coffee and tea does not have a faint taste of chlorine. So good for drinking and cooking. That was the goal, and it works.

The final comment which we cannot give now is length of service and swapping. In researching a product, we learned that the "Advanced" filter was good for 2000 Gallons, the Maximum is only good for 1500 gallons. Since the filters are interchangeable, we went with the advanced to start, and we are happy with it. Less expensive, good performance and longer life. So we will stick to that. The filter is supposed to be easily swapped when its time to change it, and considering the ease of installation I can't see that being different. Plus, no priming and 1/4 turn to swap it. We will see. It is considerably easier to use than the filter system in our previous home.

Conclusion: Does exactly what we wanted/expected and for a very reasonable price.
