sublime filtering, even of very high tds reading irish tap water.
The zero water filters are so good compared to the cheaper stuff. Really take stuff out instead of just making tap water taste better. Have done the tds test on pricey bottled water and the zero water filter wins by a lot. The cheapest way to get the incredible filters, is to buy a 6 pack from waterdrop_filters on ebay uk.
Easy to use and fill, provides fluoride free water. I didn’t realise most filters don’t filter out fluoride so was very pleased to find zero water filters, especially this big one that doesn’t need filling often. Even comes with a tester that comes up 000 (hence the name I guess!) when my tap water comes out way over 200 before filtration with the same tester. Well worth the money, would recommend.
