Elkay51300C_3PK WaterSentry Plus Replacement Filter (Bottle Fillers), 3-Pack

We use this filter on our Elkay water fountain at school. Our city's water tastes terrible unless it is run through a filter. One filter lasts for an entire school year for us and has been invaluable since we have capped off the drinking aspect of the fountain and currently use only the bottle filler.

This unit works great
