It's great that you decided to buy a water fountain for your pets, since it ensures fresh water by constantly recirculating it through a filter. That being said, your filter really should be of the utmost quality, and using an activated carbon medium to extract the majority of contaminants, including chlorine, debris, saliva, and even bad tastes and odors, only the purest, cleanest water to stream back for your pet to drink. Be sure to replace filter every 6-8 weeks to keep that water fresh!
