Truelife SonicBrush K150 UV
Entrust your dental hygiene to a sonic brush using advanced SonicTrue® technology. Producing gentle vibrations, the bristles of our toothbrush oscillate at a speed of up to 80,000 strokes per minute, effectively removing up to 99% of dental plaque. Treat yourself to gentler care, and a radiant smile without giving bacteria a chance to thrive. And as part of the package, you get a charging base with a UV steriliser to disinfect the brush head, destroying up to 99.9% of bacteria. Perfect for travel, it is compact, comes with a practical travel case and has a battery life of up to 45 days. Plus, three spare heads come included: Sensitive, Standard and Whiten.
SonicTrue® technology
Oscillating at 80,000 movements per minute, it removes the maximum amount of dental plaque.
UV steriliser
Effectively disinfects brush heads, killing up to 99.9% of bacteria and helping to keep your brush clean.
15 cleaning combinations
3 different cleaning modes (Clean, White, Massage) with 5 levels of cleaning intensity.
45 days per charge
Take the toothbrush wherever you go.
A design that works
The Truelife sonic brush charges on the charging base, which, thanks to its sleek design, will look great in your bathroom. The base included a UV steriliser, which uses UV radiation to effectively destroy bacteria, viruses and fungi that settle on the brush heads and prevents them from spreading.
SonicTrue® - effectively cleans and destroys dental plaque
SonicTrue® technology works by gently vibrating the bristles of the brush at high speeds to effectively break up and remove dental plaque. Oscillating at 80,000 strokes per minute, it forces water and toothpaste into interdental spaces and destroys plaque, stains and bacteria. Sonic technology is also gentler on teeth enamel than cleaning with a conventional toothbrush or electric rotary brush.
Adapts to your needs
With 3 different cleaning modes and 5 levels of cleaning intensity, our sonic toothbrush provides 15 unique combinations to customise the cleaning to your needs. As well as the basic CLEAN mode for perfectly clean teeth, you can also choose WHITE or MASSAGE to gently stimulate your gums. For each individual mode, there are 5 intensity levels.
Uncompromising quality at an affordable price
With the SonicBrush K150 UV and its wide range of accessories, take care of your dental hygiene needs in the comfort of your home and on the go. Out of the box, you get 3 different replacement heads - Standard for normal cleaning, Sensitive for more sensitive teeth and Whiten for a whitening effect. Each head can last up to 3 months of use, after which they begin to fray, lose effectiveness and accumulate bacteria. For convenience, the heads have special blue bristles that fade after 3 months, so you know exactly when it’s time to replace them. Plus, there’s a handy travel case that fits into any piece of luggage.
