  • Free UK/US recycling with mailer included.


SURI’s Sonic Replacement Heads are made from cornstarch with bristles derived from castor oil, offering an eco-friendly option for effective oral care. Designed with a wave-shaped medium-soft bristle pattern, they clean between teeth while being gentle on sensitive gums, removing plaque and debris with ease.

Designed exclusively for SURI toothbrushes, each pack includes 3 durable heads.

In the UK and US, SURI ensures hassle-free recycling of used heads. Each set includes a compostable pre-paid mailer—simply post it back. And if you happen to lose the bag, you can use their freepost address as an option.

Why It's Healf

SURI addresses the pressing issue of toothbrush waste, with over 4 billion ending up in landfills or oceans annually. Electric toothbrushes only worsen the problem with plastic components and unrecyclable batteries. Their toothbrushes on the other hand, are designed with the planet in mind, using innovative bio-based materials like cornstarch and castor oil to reduce plastic waste. The sleek aluminium body is lightweight and durable, with components designed for reuse to minimise waste. And by partnering with ClimatePartner, SURI measures, reduces, and offsets its carbon footprint. Their approach makes it easy to support a more sustainable, eco-friendly personal care routine.
