This unit replaced a much larger tank style RO system from another manufacturer. Not only does my G2 take up less room than my old system, it was easy to install and works great.

It was a fantastic sale price which I couldn't pass by. And this product had high ratings when checked out online and by AI. I also added and extra filter to add some essential minerals. It was easy to install as the hoses all matched the old unite, I removed perfectly. I can say much about the taste as the mineral filter changes it. What I like about this product is that filters are easy to find and purchase. The last RO I owned the filters were very hard to find and the company sometimes would not have them in stock.

I'll make a long review short. Need a 1-inch diamond drill bit to install on some setups. The drain adapter doesn't fit 1 1/2-inch pipes. If you already have an air gap, I would order a dual air gap and hook this into it (this is what I did). They make them for dishwasher and 1/4 inch push in water lines. The main water hose had a hole in it; I was able to trim it. Cheaper attachments than I'd like. Louder motor and slow water flow than I expected. The taste is a bit plastic. Overall, okay.

The water flow to fill items is a bit slow and there is a noticeable humming noise when using. Other than that, it's a great, we'll made system. I would buy it again.

Dear customer,
Thank you for your patience.
We are extremely sorry for any trouble caused to you.
The TDS value depends greatly on the local water quality, and it is normal for the TDS value to rise sometimes.
If it is convenient for you, we would like you can provide the TDS value of your raw water and the filtered pure water, so as to help you further answer your questions.
If possible, we suggest that you can provide relevant photos or videos to our email service@waterdropfilter.com, our technicians will help you solve the problem professionally.
If you have any questions or concerns, please feel free to contact us.
Kind regards,
Mia Lauren
