The activated carbon particles in the filter can produce trace amounts of carbon dust during transportation. Therefore, please rinse the filter in clean water for 2 minutes (to wash away any floating carbon) before use to ensure better filtration. If the water bowl shows black after cleaning the filter, simply replace the water for safe use.
Note:
Activated carbon effectively filters out unusual colors and odors from the water. If ingested, it can be expelled through feces without any toxic side effects.
Some pets consuming colored foods containing beetroot powder or purple sweet potato powder (fruit and vegetable powder) can cause red marks on the filter and the bottom or edges of the water bowl, which is normal. It is recommended to follow the cleaning guidelines to maintain the quality of the water for your pets.
