  • After 20 washes, or when the cartridge is full, swap it out with a clean cartridge. Watch this helpful guide from PlanetCare.
  • Allow your used cartridges to fully dry, then store them in a box (if possible, reuse the box your 12-pack was sent in).
  • Once you've collected 12 cartridges (or 15, if you're including the ones from your Starter Kit), seal the box and use the return shipping label (provided) to send the used cartridges to Celsious. If you misplace your label, just reach out to our team and we can send a new label via email.

Pro Tips

Try washing clothes less often, with cold water and on shorter cycles to reduce microfiber shedding. If you wash a lot of cotton and/or have pets that shed a lot, you might find your cartridges need to get replaced before the 20th wash.
