Summary You have a cool Waterdispenser like the Pet Mate for you Cat (or Dog) but you are sick and tired to buy the massive overpriced filter again and again for each month? This has an end here! Print your Filterbox yourself and get the active carbon in a big amount (3 Liter!) for a few bucks with the Filterfleece. You can count yourself lucky now, because you can be sure that Your cat won't survive the run out of your carbon supplies and you maybe won't either - sorry for my sarcasm. ;D You don't have a Pet Mate Waterdispenser?
