AirJet Electric Toothbrush Series

Cleaning beyond where bristles can reach

AirJet

A disruptive technology that redefines interdental cleaning through fluid dynamics.

The surfaces bristles can touch were never the problem.

Traditional electric toothbrushes — sonic, oscillating-rotating, magnetic levitation — all share the same fundamental mechanism: bristles contact the tooth surface → vibration/rotation generates friction → plaque is mechanically scraped away.

This works reasonably well on flat, accessible surfaces. But between teeth —in the spaces bristles physically cannot enter — this mechanism fails entirely.

And most of cavities begin precisely in these interdental spaces — where bristles never reach.

AirJet Technology Breakdown

Boosted Bubble Chamber

A dedicated pressurization chamber inside the handle aerates the water-toothpaste mixture at high speed, transforming it into a continuous stream of high-density microbubbles.

This is not ordinary "foaming" — each microbubble measures mere tens of microns in diameter, uniformly suspended in liquid, forming an energy-carrying cleaning medium.

Coandǎ Brush Head

Named after the "Coanda Effect" in fluid dynamics — when a liquid jet approaches a curved surface, it naturally attaches and follows the contour.

The AirJet bubble brush head harnesses this physical principle to guide microbubble flowprecisely along the natural contours of teeth and automatically into interdental spaces.

No technique required. No deliberate aiming. The fluid finds its own way.

Vortex Cavitation

AirJet draws inspiration from this principle, recalibrating the coupling betweenvibration frequency and oscillation amplitude to replicate a reverse Kármán vortexstreet effect within the oral cavity. Each micro-oscillation of the brush head is no longer mere mechanical friction — it becomes a directional forward-propelling fluid pulse, driving high-density microbubble streams precisely into the depths of every interdental space.
