## Description

Waterdrop Reverse Osmosis Alkaline Water Filter

Review: Fresh clean taste - I’ve been very happy with the Waterdrop ALK35 filter. I added it to my reverse osmosis system to complete my water filtration process, and installation was simple, just take your time and make sure the tubing is cut clean and straight. What really impressed me is the taste. The remineralization filter adds back beneficial minerals like calcium, magnesium, sodium, and potassium, giving the water a crisp, refreshing taste that reminds me of premium bottled water. The best part is knowing I’m getting great, tasting water without constantly buying plastic bottles or worrying about microscopic nanoplastics. For me, the ALK35 was the perfect finishing touch to my RO system.
Review: Will buy again - Instantly noticed the change in water quality.

### ⭐ Scam not certified at all
*by C***. on 26 September 2025*

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%
