Received a batch with a Faulty seal

Update: I buy in advance when these are on sale, and have just discovered that the batch I have is faulty. The seal leaks. Very disappointed. Dropped down from 3 stars to 1 star. BEWARE! Only removes 41% Flouride Very disappointed to recently learn that these water filters only remove 41% flouride. I checked the website when I discovered this and found this: “When tested in accordance with the NSF's protocol based on a 40 gallon filtration (double the rated usage), ZeroWater removes 41% of Fluoride from your tap water” Will still continue to use until I find an alternative. Ocado should update their description box.

pricey but quality

Unfortunately, unless you purchase a distiller, you won't achieve the quality of water filter zerowater provides. It removes all the badness from disgusting tap water into something more pleasurable. But be warned, it removes everything, even the goodness such as minerals. So as long as you have a healthy diet or replace them, you'll be fine. But definitely worth it.

expensive, good, frequent replacement

This definitely improves water but with two caveats: 1. Expect to replace the filter every two weeks (London TDS ~240 small family using for kettle and cooking) 2. It often filters slowly or not at all. Take it out, invert and tap, then replace. Bought on sale, at full price its quite costly. I might use a cheaper brand for the kettle to keep cost under control. Watch out for lemony tastes too, that means its time for a fresh filter.

The best filter we've had so far.

The water from the filter makes lovely hot drinks and tastes delicious straight from the filter. They are quite expensive, especially as I live in London and am going through one every 2 weeks or so but I can really tast the difference and I weighed up the cost of having a filter fitted and it was around the same price. Genuinely, it tastes great and when you taste water straight from the tap you can really tell the difference. I've been using it for 6 months now and still haven't got any limescale in the kettle.
