I'd be curious to learn more about how exactly does it work, what kind of filter system is it and how long does it last! Are there some parts to be replaced after some time?

Dear Alina, many thanks for your comment. Each filter lasts for 200l (75 bottle) or 130l (Go! bottle). Filters can easily be bought at their online shop.It depends thus on how much you use it. The filters need to be replaced after 200l resp. 130l. They are 7£ each, so very affordable. Are you thinking of getting one? Do not hesitate to write me in case you'd have any doubts.
