Ergonomic Design, Better Compatibility, Sustainable

FAQ

What is the Returnabl water filter cartridge?

A refillable cartridge for jugs and kettles that take Brita Maxtra-style cartridges. You keep the cartridge and refill it with fresh activated carbon granules every month.

How much does it cost?

The starter kit is £20 and includes the cartridge plus 3 months of refills. After that, refills are £12 for 3 months or £30 for 12 months, which is £2.50 a month. You can also get the cartridge free with 12 months of refills for £30. UK delivery is free.

What does it filter?

The silver-impregnated coconut shell activated carbon reduces chlorine, improves taste and odour, and reduces organic compounds including some pesticides and herbicides. The silver helps stop bacteria growing inside the cartridge.

How often should I change the refill?

Each refill pouch lasts up to four weeks, so swap in a fresh one once a month.

Does it fit other water filter jugs and appliances?

Our refillable cartridge fits almost all Brita jugs including Brita Maxtra, Maxtra+ & Perfect Fit, Marella Jug, Brita Kettle, Maxtra Pro, Aqua Optima, Tesco Jugs, AmazonBasics branded Jugs, Wilko etc. Also suitable for use in Morphy Richards and Russell Hobbs filter kettles.

What's in the filter?

Coconut shell activated carbon to absorb volatile organic compounds, chlorine, pesticides and herbicides. Silver-impregnated into the carbon to inhibit bacterial growth inside the cartridge.

Do you have certification?

Yes Our refill granules have been rigorously tested and certified to meet international standards. Our Coconut Shell activated Carbon is certified to meet the EN12915, AWWA B604-96, and NSF 61 standards.

Why invest so much effort into creating such a niche product?

While this may seem like a niche product, over 100 million plastic cartridges end up in landfills every year, and the number keeps rising. By focusing on this specific issue, we’re offering a better, more affordable, and eco-friendly solution to a problem that impacts us all and contributes to environmental harm.
