THE CARTRIDGE'S OTHER HALF
No Slaky on the wall yet?
The cartridge lives inside the Slaky shower head — one polished object, filter included, $30 off on subscription.
Quick answers.
Fit, timing, and the lazy option.
Does it fit my Slaky?
Yes — this is the standard cartridge for every Slaky shower head, both finishes.
When should I replace it?
About every 90 days — sooner or later depending on your water quality, temperature, and how much you shower.
Do I need to buy these manually?
Not if you subscribe on the shower head page — a fresh cartridge ships automatically about every 90 days, and you can pause, skip, or cancel anytime.
