Returning your used Indi™ Filter cartridges is as easy as 1,2,3...

1. Fill out the return form here and we will send someone to collect your parcel. We will advise on a 3hr collection time slot. The collection driver will have a label to attach and we will email you the FREEPOST label too if you want to print + stick it on in advance. 

2. What to do with your old cartridge before you send it: Once the old cartridge is removed from your Indi™ filter ensure that it is dry before placing in return packaging (we suggest just leaving it on some kitchen towel or toilet paper to gently dry).
Top Tip:  Your NEW cartridge box works best for packing and sending.

3. Packing your cartridge up: Pop your used, dry Indi™ cartridge into the box your new one arrived in. Make sure this is sealed securely. Put your provided FREEPOST sticker on the front of the packaging either before your driver arrives or using the label they provide. 

Indi™ filter users simply capture their microfibre pollution in the sealed Cleaner Seas™ cartridge and can rest assured Cleaner Seas Group™ will dispose of it responsibly.

After approximately 100 washes the indicator light will illuminate to tell you that you need to change your cartridge.  Order a new online HERE and pop your used/full cartridge in your freepost envelope back to us. We’ll harvest the microfibres and refurbish the cartridge ready for it to be used again.

Installation Guide

How it Works.

The Indi™ filter uses a patented, cartridge-based system to capture up to 90% of microfibres from every wash: down to the smallest 1 micron.

We believe in circularity, which is why Indi™ is not only made from recycled materials, it also employs a free, returnable cartridge system that enables us to recycle your microfibres and refurbish the cartridge over and over again.
