Microfiber Filter Refill Cartridges


Thank you for using the PlanetCare microfiber filter with your washer! The filter captures a wide range of fiber sizes—from under 20 microns to 5 mm—and reduces the amount of microfiber pollution entering our waterways from laundry.

This 12-pack of refill cartridges will last ~240 loads. The cartridges are compatible with the housing from PlanetCare's Mini Starter Kit and XL Starter Kit.

When you purchase a refill pack from Celsious, you'll be eligible to return used cartridges to us in New York. Complimentary return labels will be generated through the original order.


    • Cartridge length: 10"
    • Diameter: 2.75"


    • After 20 washes, or when a cartridge is full, replace it with a clean cartridge. Watch this helpful guide from PlanetCare.
    • Allow used cartridge to fully dry.
    • Place the used, dry cartridge in a box (if possible, save the box your 12-pack was sent in). Once you've collected 12, seal the box and drop us a note via email/chat box. A team member will be in touch shortly with your shipping label.


    If you wash a lot of cotton and/or have pets that shed a lot, you might find your cartridges need to be replaced before the 20th wash.

    Try washing clothes less often, with cold water and on shorter cycles to reduce microfiber shedding.


    Enjoy free shipping on orders of $50 or more! A $5 shipping fee will be applied to all other orders. Please allow 3 business days for our team to prepare your order. Packages sent to addresses within the U.S. should arrive in 4-10 business days.
