Waterdrop G2P600 Remineralization RO Water Filtration System for Home

Really good RO filteration

Easy to install, reasonably compact, perfect for my needs for filling coffee machine and kettle in hard water area. Pump is noisier than previous systems I've had but then the flow is better also meaning no external tank is needed so worth the trade off.

Water much cleaner and tastes much better

I waited about a month before submitting this review so I could properly test the system.

This water filter meets my expectations. It doesn’t take up much space under my sink, which was very important to me. I did have to install a power socket under the sink for it, but it was definitely worth it.

I tested the water quality with a TDS meter. The normal tap water in London was around 270, while the filtered water—after letting it run for about 10 seconds—measured around 22, which is excellent.

I like the taste of the water. Some people might prefer a different taste, but for me it’s very good. The water flow is also quite strong, and changing the filters seems much easier compared to many other RO filter brands.

Overall, I’m very satisfied with this purchase.

We finally drink our tap water again. That alone makes this worth it.

Our water here is extremely hard, to the point where drinking straight from the tap just wasn’t pleasant. Before this system, we were using a Zero Water filter and replacing cartridges every two weeks, which was expensive, annoying, and still not ideal.

Installation took me around four hours. Not because it’s complicated, but because I chose to do it properly. I drilled holes to route electric cables and hoses neatly, installed a new 3-way tap so there’s no separate filter tap, and added the mineralisation stage. If you have basic DIY skills and patience, it’s a very manageable job.

So far, the water tastes great. Clean, soft, and genuinely enjoyable to drink. The mineralised option was a good call for us.

We don’t yet know exactly how long the filters will last in real-world use, but if they come even close to what’s promised, this system is far cheaper than our previous setup and obviously cheaper than buying bottled water. Plus, no plastic waste and no constant cartridge stress.

Early days, but right now we’re very happy with it.
