- Reviewed in the United Kingdom on 9 August 2024Value for money and very easy to install
- Reviewed in the United Kingdom on 13 March 2022This filter filters all minerals from the water producing distillated water. That water is not suitable to be drink without remineralisation stage, which this filter not provide. I contacted the company about that concerns and they told "it's common myth, this water is perfectly safe to be drink". This is not only misleading but also life threatening advice. Returned. Stay away!
- Reviewed in the United Kingdom on 5 February 2021Great product, great customer support! 5*
- Reviewed in the United Kingdom on 2 September 2021It did take a little while to install. Two negatives,
1 the installation manual isn't great, so I watched a few videos on YouTube.
Non were from Geekpure, but they all seem fairly similar.
2 The Feed Water Diverter Valve supplied was plastic and did not fit onto the existing plumbing, so I had to order a different one of Amazon.
But once this was done, it all was straight forward.
I have a tds reading of 0 after filtration, before it was 486.
- Reviewed in the United Kingdom on 4 November 2023Won’t install with English plumbing and leaks profusely. Too late to return so extremely upset.
- Reviewed in the United Kingdom on 11 February 2021Hi everybody, previously I left the review describing some problems with the installation and quality of water. After that we contacted the seller and they helped us a lot to sort everything out. Now our filter is superb and we are enjoying the excellent water. Please, mind a few tips:
1. Always flush a new filter before using for at least 40 minutes.
2. Before using the system the tank should be emptied twice. It takes about 8 hours (4 hours each).
3. After installation always check your system for leakage. In our case the tube which goes from the valve to the membrane cartridge input was too short and because its tension the thread in the input became loose which resulted in small but substantial leakage. We had to tighten the thread and install a longer tube.
4. Also: in our case the membrane filter was not installed in the cartridge and placed separately. The plumber decided that it was a spear part and didn’t install it. After installation without membrane the system started to tremble producing strange noises. So it took us more than a day to understand what went wrong but eventually we did it and installed the filter.
The seller helped us a lot and now the system is ok. By the way the system allows you to use either DI or alcaline filter.
We definitely recommend it buying. We are happy with our purchase now.

5.0 out of 5 stars Gane changer for my life style
I'm obsessed with this water filter! I was skeptical at first, but it's been a total game changer for my kitchen. The taste of my water is so much cleaner and fresher now. Plus, it's super easy to install and maintain.
I've noticed a huge difference in my cooking and drinking water. My coffee even tastes better! The filter is also really affordable and the replacement cartridges are easy to find.
Overall, I'm so happy with this purchase. If you're on the fence, trust me and give it a try. Your taste buds (and your health) will thank you!
Happy hydrating!
- LeonardReviewed in the United States on 3 October 2023
5.0 out of 5 stars Very reasonable price, and a relatively easy install
Big picture, this is a great RODI filter. I'm using it primarily for my hydroponics, but the water it puts out tastes great and tests exceptionally clean. For the most part, the installation was very easy, but the instructions made a few assumptions between steps that caused me to go back and repeat a step. The clean to waste ration is really good to. I haven't measured it, but I would guess that it is better than 4:1 (clean to waste)
