The Canopy Bath Tub Filter Cartridges

Inside every Canopy Bath Tub Filter cartridge is a tri-media blend that works hard to clean your water before it hits the tub. This includes:

  • Granular Activated Carbon (GAC) from coconut shells, which absorbs chlorine and other organic contaminants that can cause odor and irritation.
  • Calcium Sulfite, which is highly effective at rapidly reducing chlorine (up to 99%) and removing suspended particles.
  • KDF-55, a copper-zinc formulation that reduces heavy metals, chlorine, and scale buildup while inhibiting bacterial growth.

Together, these materials work to filter out chlorine, chloramine, iron, zinc, and other harmful impurities, giving you a gentler, more skin-friendly bathing experience every time.To keep your water as clean and gentle as possible, we recommend replacing the filter cartridge every 90 days.

How often should I change my filter cartridge?

To keep your water as clean and gentle as possible, we recommend replacing the filter cartridge every 90 days. However, depending on your water quality and usage, you may need to replace it sooner. A good way to tell if your filter is ready for a change is by sight and performance: if you notice a decrease in water flow or see that the filter media has turned fully white and black, with no remaining golden-brown granules, it’s time for a new cartridge.

Swapping out the cartridge is quick and easy, thanks to a built-in finger slot that allows for effortless removal.
