About this product
Solid bamboo, no hidden plastic core. Most bamboo electric toothbrush heads on the market are a bamboo sleeve over a plastic inner. These are bamboo all the way through, precision-engineered over two years and copyrighted by the brand.
The bristles are 100% castor bean oil, plant-derived rather than fossil-fuel nylon. The head is slim with a small profile, designed to reach the areas that matter. Each pack contains two heads, roughly six months of brushing. Packaging is a paper pillowpack with a biodegradable natureflex inner bag.
Compatible with all Philips Sonicare click-on models including DiamondClean, ProtectiveClean, 2 Series, 3 Series, HealthyWhite and EasyClean. Not compatible with screw-on models.
Why it's BRiMM
It took Truthbrush an impressive two years of engineering to develop this head which is solid bamboo with no plastic hiding inside. The bristles are 100% castor bean oil rather than conventional nylon.
It fits over 150 Philips Sonicare click-on models. The clean is the same. The only difference is that when you replace the head every three months, the bamboo composts and the packaging biodegrades.
That is a lot of plastic removed from a daily routine.
How to use
Press the bamboo head firmly onto your Philips Sonicare click-on base until it clicks into place.
Brush as normal: two minutes, twice daily.
Rinse the head thoroughly after each use. Store upright, away from standing water.
A small gap between the base of the head and the handle is by design and does not affect performance.
Replace every three months. End of life: remove the bristle section (general waste), compost the bamboo head or return via TerraCycle.
Not compatible with screw-on Sonicare models. Truthbrush is not affiliated with or endorsed by Philips.
Pairs well with Truthbrush Interdental Brushes for full bamboo oral care.
