Does what it’s supposed to do
Unit was easy to install and performs as expected. Prior to installation my RO TDS was 7ppm. After installation TDS is now 27 ppm and pH is 7.8. From what I’ve read I was expecting a 20 point bump and that’s exactly what I got. Water taste is similar to some of the bottled “Smart Water” products. Both pH and TDS meters were calibrated with calibration fluids prior to test. (Leftover from planted aquarium days) I will occasionally retest to determine when replacement is required. I would be happy with 5-6 months of service. Based solely on my experience, I would recommend.

Scam not certified at all
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%
