Easy installation great taste

I was worried about installing this filter myself, but it was incredibly easy. It fit perfectly on my faucet, and the water tastes fantastic. No more chlorine smell and looks great!

I tried Britta jugs, but with a large family, frequent refilling became a hassle. This is perfect for us. We enjoy clean water with significantly reduced plastic usage. Highly recommend!

Super easy to install
We needed a water filter but didn't want to pay for a large system and installer. Water tastes great and is was super easy to install. Simply twisted it on with the provided fitting.

Tested and it works
I tested the water before and after installing the filter… Glad it works… Even from taste alone I can tell the difference.

We've had cryptosporidium outbreaks in ireland. Ceramic filters are highly effective at filtering this out so that's why I went with this system. Very convenient.
