A Better Bath Starts With Better Water

This replacement cartridge is designed for use with the Bathtub Filter Series and fits all bathtub filter colors. It helps maintain effective reduction of chlorine and other common bath water contaminants for a safer, more comfortable soak.

Filter lifespan can vary depending on how much water is used per bath and the chlorine levels in your local water supply. Based on decades of real-world use, most customers achieve the best results by replacing their filter every 3–6 months or approximately 30–50 baths.

Prolonging use beyond this range can reduce filtration effectiveness. Replacing your cartridge on schedule helps ensure continued contaminant reduction and the cleanest bath water possible.

Bath tub filter

Great. Works really well takes out all the chlorine smell from city water. And our skin feels softer.

Bathtub filter

This works very well. It is a sort of old fashion arrangement, but for filtering out chlorine and fluoride it is an excellent choice!
