The filter and the deep clean run on different clocks
Water keeps moving in a fountain, so it can look clean while a slick film builds inside the pump and the channels. This calculator takes the date the filter was last changed, the date the unit was last taken apart and washed, and the two intervals printed for your product, then reports each next date, the days left and which job comes first. Anything already overdue is shown as the number of days past.
No published table of recommended filter or cleaning intervals for pet fountains could be verified. Filtration and pump design differ from product to product, and so do the intervals, so this page sets none of its own and only works out dates from the manual you have. Current as of October 2026.
Nothing here judges water quality or bacterial counts, and no cleaning agent or dilution is suggested. If the water feels slimy or smells, wash it that day whatever the dates say. A pet drinking much more or much less than usual can be signalling a kidney or sugar problem. This tool is for reference only and does not replace veterinary care. Contact your veterinarian right away if you notice symptoms or suspect a problem.
Frequently asked questions
Do not guess one. Ask the maker's support team or check the spec on the product page. This page does not set a recommended interval for you.
The filter catches debris, but the film inside the pump and channels only comes off in a deep clean. That is why the two intervals are entered separately.
The days past are reported as they are, with no judgment attached. If it is overdue, do the job today and enter the new date.
