## Description

Waterdrop Reverse Osmosis Alkaline Water Filter

Review: I bought this filter back in July 2025. This is a late review. As this filter was very easy to install there are a few concerns I have about it. 1. Customers service number works but the customer service will for sure mislead you. Fact. 2. It does not up your PH whats so ever. I know this as I went back to work for a water filtration company again. We tested it. Its just plastic with stuff in it. 3. It states it certified. I fact its not. Only there units are. 4. The web description states its certified thats not at all true. 5. Anyone with a 5 star review has no idea what there talking about. I have been in the water industry for over 25 years and I know for a fact that this is just weight in your Revirse Osmosis system. I suggest you looking elsewhere like you local water distributor that sells water and water dispensers. No not walmart. PH filter are special and must have the certificate sticker on it 100% This filter is an absolute joke and not worth the money. It's a scam 100%
Review: 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 desertcart'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
