Is it possible to replace the plastic case this filter goes into? I accidentally destroyed mine, and don't see them for sale.

Answer by LucyJun 22, 2024
I had the same thing happen. Found a replacement on Amazon.

How long should I rinse these filters before using them? It seems if I rinse or don’t rinse these, the water turns gray from the charcoal. I have concerns about the taste, appearance, and health concerns with this charcoal in the water.

Answer by ChewyMay 30, 2018
We recommend a quick rinse before adding it to the fountain. Prolonged rinsing prior to being used in the filter can contribute to extra debris in the water.

How do I replace the new filter into the fountain?

Answer by ChewyMay 02, 2019
Rinse the charcoal filter thoroughly in cold water to help remove any excess and loose charcoal dust. Once the filter is rinsed off, place inside the filter housing case with the larger side facing down. The filter will only fit inside the case one way, if it does not fit, flip it over. Attach the lid to the filter housing case, press down until you hear it snap in place.

How often does the filter need to be changed?

Answer by ChewyJul 17, 2019
These filters should be replaced every 2 to 4 weeks; this helps extend the life of your fountain and pump.

In the past, I have ordered generic filters for our PetSafe fountain. They were inconsistent and I stopped using them when a fine white grit started showing up in the water. I’m glad to say that these seem to be of a much higher quality. They also fit the housing better.

I have a water fountain for my cat, which uses these filters. They are easy to rinse off and insert into the compartment. Since there is 4 in a pack, I have enough to last several washes of the fountain without worry about running out too fast.

Awful product!

I have three PetSafe water fountains, so these are a necessity. My cats love drinking from the fountains so I purchase the accessories needed to keep the fountains

I have three PetSafe water fountains, so these are a necessity. My cats love drinking from the fountains so I purchase the accessories needed to keep the fountains working properly. The quality of these filters gets worse with each order. Flimsy manufacturing. They get slimy very quickly and need to be replaced weekly to keep the water in the fountains clean. The purchase price seems to be increasing every time I order them. PetSafe has a great product with the cat water fountains. They really should find a different source for the manufacture of this component.

Pink slime in bowl after 24 hrs

Used distilled water, soaked the pump in diluted vinegar and rinsed well. Used clean filter and still had pink slime within 24 hours. Cats would not drink out

Used distilled water, soaked the pump in diluted vinegar and rinsed well. Used clean filter and still had pink slime within 24 hours. Cats would not drink out of fountain after initial cleaning. Whole system a waste of money.

Quiet!

Extremely quiet, which the cats prefer. It does get noisy when the water level is too low, which is a good thing.

Received my order,, delivered to front of house and bottom of box was completely saturated with parts of the box missing. Please see attached photos. The arm and hammer solution cover was not tightly sealed and although packed in a plastic bag, had leaked out in it’s entirety, and ruined the cardboard box as well as saturated the 2 boxes of filters for the fountain by. Those filters, both boxes of 2, all 4, had to be disposed of since the Arm & Hammer Litter Plus Oxiclean Pet Stain & Odor Eliminator, 32-fl oz Spilled all over the boxes and saturated the boxes of filters and the filters since not enclosed in anything in the box. I had to throw out the 2 boxes I purchased, as well as the empty bottle of Arm and Hammer Litter Plus oxiclean pet stain and odor eliminator 32 fl oz. that leaked. Everything else in the order was wiped down to get the solution off the packaging so as to not poison my Mittzy. Tedious, but necessary and hopefully nothing will cause Mittzy to become ill.
