Hi! This site exists only to sell Katadyn water filters. It is not owned by Kadatyn in whole or part, nor is it a part of, or integrtated with Katadyn in any way whatsoever.  Katadyn has had no input to the content or the design beyond their own wording provided to describe their own products within the integral search engine. I am offering their products as an affiliate and will earn a commission on every sale.

Apart from that, I hope you find one of the excellent Katadyn water filter products you are looking for and that you have a very pleasant shopping experience.
