LOVE IT

We swapped from another well known brand that was much more expensive. But Waterdop tastes far nicer and is so much cheaper in the long run. Not only that, it was far easier to fit and came with spare parts, so fitting it was a breeze compared to the other one. 100% recommend. Made life easier and water taste so much better.

Easy to fit if there are no pipes in the way! Did manage.

Seems solid, easy to fit when things aren’t in the way. Working with no leaks. Water tastes nice.

Great tasting tap water

This filter has proved to be a great investment, our tap water always had a smell of chlorine and chemicals taste. Not anymore the 0.01 ultra filtration has removed all that. Water from the tap tastes great and we love a cup of fresh tea which now taste fantastic.

Simple to fit

I became interested in these under sink filters after seeing them advertised on social media. Waterdrop seemed to be a proven design and further investigation showed it would meet my needs.
Fitting is straightforward but fiddly, depending on your access to the cold water supply. To be honest, I couldn’t taste any difference in the water but I trust it to remove contaminants. I simply don’t believe in anything the water companies do now so this provides some reassurance. It also works out cheaper than buying bottled water. Be aware that there is a reduction in flow rate from the tap after fitting but it’s not an issue.
I would definitely recommend this.
