Waterdrop𝐀𝐥𝐤𝐚𝐥𝐢𝐧𝐞 Water Filter WD-ALK35, Alkaline Filter for Reverse Osmosis System, pH Balance and Restore Minerals for RO Alkaline Filter, Under Sink Water Filter, 1/4" Quick Connect

The mineral fiter works really well - the water tastes amazing with this add on filter. We purchased the 2-pack. The first filter was defective, while the second one worked fine. Since Amazon doesn’t have a choice to request a partial return and replacement, I reached out directly to Waterdrop’s customer service team and they immediately responded and sent us a replacement filter for free. I want to especially thank Harper who made sure that all issues were totally resolved. We have the Waterdrop G3P600 RO under sink filtration system which we have been using daily for over 5 months. The system delivers amazingly clean water, and coupled with the excellent customer service we have experienced, we know that we made a great choice with the Waterdrop company!

We had a full house water conditioner at our other house but had to move. My husband's disabled and was struggling to get upstairs. Our house is one floor now. We all love it the water was nasty now it's yummy. My handyman put it in thank God he's so knowledgeable.

The product works as expected and the TDS levels when tested are in the perfect range. Water also tests great now with the addition of this filter. I had to reach out to Waterdrop for a few questions and Rebecca from customer service went above and beyond in identifying the issue I was running into and even sent across a component I was missing. Very happy with the business. Highly recommended.

the cartridge was unexpected addition to the Waterdrop G2 Reverse Osmosis system followed instructions closely but it leaked at outlet side .Made the mistake of mounting under cabinet as instruction suggested Thus could not get tubing to release when it leaked .Contacted supplier they were more. than happy to replace , promptly .Best Customer Service Customer service mailed replacement faster than Amazon's first mailing . Second install purchased more tubing from Home Depot and cut tubing long enough so I could remove from under cabinet before trying to remove cartridge and this made it easier to remove tubing following instructions, Also added duct tape to tubing when installing so had a. firmer grip pushing in tubing beyond the initial click , So far works great , City Water does taste better Very satisfied customer happy with purchase

I kind of ordered this "filter" on the spur of the moment. Then I read some reviews and once it arrived - I was very hesitant to even open the package...In the end, we decided to try it, and I'm glad we did. The water straight from the filter had a somewhat "blunt" taste - this thing brought the taste back. Not alkalinity, though - but for that we got some drops.Installation was a bit of a pain - yes, it did leak initially. I had to re-do the cuts on the tubes several times until I finally got a straight, even cut. I also marked the tubes with lines to indicate how far they should go in. This helped stop the leaks. So far so good - it's online for about 2 months and all connections are dry.I'm guessing: when the time comes to replace it, it'll be another fight with the leaks, and more cutting - may be useful to order some extra tubing. But I don't think I'll give up on this, it works.

works great brings back all good minerals lost with the ro dystem

Easy installation. Adds minerals back to Reverse Osmosis systems. Highly recommend.

Amazing taste to the water.
