Waterdrop Remineralization Under Sink Water Filtration, 1/4” Quick Connect Post Filter for RO Reverse Osmosis Filter System, Restore Essential Minerals

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!

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

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

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.

Amazing taste to the water.

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

The product was excellent. But, the customer service was even better. Thank you Water Drop! I cannot emphasize enough the personal care I received from Harper and his customer care team.

I’ve been using the WayerDrop 600G without demineralization for a long time. I always thought it tasted really clean but a bit flat. It tastes perfect now there’s no bottled water that matches it.
