Drinkwell pet fountains are the result of an observant veterinarian and pet lover who noticed her pet cat, Buckwheat, enjoyed running water more than that in his bowl. Since the creation of the original fountain, the Drinkwell line has added several creative models to suit all types of pets and owners. Drinkwell pet fountain assembly can be quick and easy.

Charcoal filters are available in almost all models. The filters help purify the water and create a cleaner, better tasting water for your pet. Nearly all models follow the same procedure for filter changing.

Drinkwell Pet fountain filters

There are two types of charcoal Drinkwell pet fountain filters: high-capacity filters and original filters. Original filters have two segments that divide and distribute the charcoal through the water. The high-capacity filter has six compartments to more thoroughly filter your pet's drinking water.


Both types require changing every two to four weeks to maintain great tasting, purified water for your cat or dog. Drinkwell also has round charcoal filters, small, mesh-like pod filters, and foam filters for different fountain models.

Changing standard filters

The high-capacity and original charcoal filters are compatible with the Original Drinkwell pet fountain.


To change the filter, unplug the fountain and remove the housing lid by lifting it up. Remove the housing lid, dump out the old water and remove the filter housing, if equipped. Remove the old filter by pulling it out of the slot. Clean the machine according to your model's instructions.


Rinse the new filter under cool water and stick it into the slot with the narrow side pointing down and the black side facing the spout side. Push it all the way down into the filter compartment.

What type of filters?

Drinkwell Pet fountain filters may not all have standard filters. For instance, the Avalon and Pagoda Drinkwell fountain models do not use the standard filter, but use foam filters instead.



Fountains with towers

The Avalon and Pagoda models also have towers that cover the filter housing and hold water for a secondary drinking area. To maintain the towers, take off the rubber grommet by pulling it straight down. Remove the white, conical filter housing that sits on top of the pump, open it and remove the charcoal filter. Rinse the new charcoal filter with cool water and place it into the housing with the larger side facing down.


Find the small raised post that houses the cord and remove the rubber cap. Dump the water from the fountain. Remove the pump by firmly pulling it up to release the suction cups; clean the machine and then place the pump into the D-shaped hole of the new filter, making sure the cord for the pump rests gently over the top of the filter.


Reassemble the fountain. Fill the fountain by pouring new, fresh water directly into the bowl.

Drinkwell 360 fountain filters

The 360 Fountains have yet another type of filter; these filters are small, pod-like filters. To change the filter on this model, unplug the fountain and disconnect the inline plug. Remove the flow-control cap and spout ring from the filter housing and set them aside. Pull the two-prong cord clips away from the bottom of the bowl and set them aside.

Next, remove the filter housing; this may be difficult, so try gently twisting the housing back and forth to pull it out. Remove the cone and pump, then dump and clean the machine. To change the filter, unscrew the filter housing cap.
