The CDC recommends testing tap water for harmful germs or chemicals and choosing treatment for the identified problem. If those hazards are absent, treatment may be unnecessary.

“Filtered” covers different processes: check the exact system’s removal claims. Distillation boils water and collects it as it cools, removing many contaminants. Some volatile compounds can remain, and bacteria can grow on idle cooling coils. These household-treatment facts do not establish a medical water choice for your cat.
