How To Replace Filters

Replacing your filter cartridge

For the cleanest water and best pressure, swap your cartridge about every 3 months — sooner if you have especially hard water or notice reduced flow.

  1. Turn off the water at the shower valve.
  2. Open the shower head. Unscrew the front face / filter housing by hand (counter-clockwise).
  3. Remove the old cartridge and discard it. You'll often see exactly what it captured — that's the chlorine, rust and sediment that's no longer hitting your hair and skin.
  4. Drop in the new cartridge, matching the orientation arrow.
  5. Screw the housing back on hand-tight and run the water for 15–20 seconds to flush it.

Never run out: a fresh cartridge every quarter keeps results consistent. We recommend keeping a spare on hand or subscribing to auto-refills so a new one arrives right when you need it.
