A new approach to daily oral care—designed around intelligent airflow, precision guidance and gentle physical contact.

How RANVOO’s airflow-guided microbubble system helps deliver a deeper clean with less mechanical stress on teeth and gums.

A new approach to daily oral care—designed around intelligent airflow, precision guidance and gentle physical contact.

For decades, electric toothbrush design has followed a simple formula: make the brush move faster and let mechanical action do the cleaning. That approach can be effective, but more speed is not always the same as a better clean. Once brushing intensity rises beyond what the mouth needs, extra mechanical force may add stress to enamel and delicate gum tissue without delivering a proportional benefit.

AirJet is designed for everyday routines across different oral-care needs.

“Less dependence on aggressive motion. More intelligent energy, delivered exactly where it matters.”

RANVOO created AirJet Technology to change that balance. Instead of asking bristles alone to reach every interdental space, the system creates and guides a high-speed stream of fine microbubbles around the brush head. Those bubbles work with the bristles and toothpaste foam to support cleaning along the gumline, between teeth and around hard-to-reach surfaces—while automatic frequency control keeps the brushing action measured and comfortable.

Inside AirJet: engineered airflow, guided by fluid dynamics

At the heart of AirJet is a miniaturized airflow and water-flow generator integrated into the toothbrush body. The internal microbubble engine pressurizes air, then channels it through the handle and into a hollow output path at the brush head. There, airflow, saliva, water and toothpaste foam combine to create a dense stream of energized microbubbles.

AirJet directs airflow through the brush head to create a controlled microbubble cleaning field.

Three coordinated actions

The result is a hybrid cleaning action: soft bristles handle direct surface contact while airflow-guided microbubbles help carry cleaning energy beyond the bristle tips. As bubbles expand and collapse, they create localized fluid movement that helps loosen plaque deposits from the tooth surface and within interdental areas.

Protection engineered into every contact

AirJet is designed around a simple principle: effective cleaning should not require excessive scrubbing. By moving part of the cleaning work into the fluid around the brush head, the system can rely less on aggressive mechanical motion. That matters because enamel and gums respond not only to how long we brush, but also to the frequency, amplitude and force applied during each session.

Measured motion, not brute force

The AirJet X5 automatically varies its operating frequency to match the cleaning process. RANVOO’s internal comparison tests reported a 39% lower operating frequency and 56% lower physical action force than a conventional electric-toothbrush benchmark. In the same test framework, the composite gum-injury rate was reported as 90% lower. Together, these results point to the intended AirJet experience: thorough daily cleaning with a gentler mechanical profile.

A brush head built to care for enamel and gums

Ultra-fine, precision-tapered bristles

The professional brush head uses bristles tapered to approximately 0.01 mm at the tip, with a stated 99.9% tapering rate. Their fine profile is designed to enter narrow contours with less poking or dragging at the gum margin. RANVOO pairs these filaments with DuPont Pro-grade diamond bristles to balance softness, resilience and everyday plaque control.

A cushioned base for softer contact

The bristle field sits within a fully wrapped soft-rubber brush-head base. This flexible perimeter helps reduce hard-edge contact if the head touches the teeth or gums, adding a second layer of protection beyond frequency control.

Air and bristles, working as one system

AirJet does not replace brushing—it makes brushing more intelligent. The bristles sweep accessible surfaces, while the guided microbubble stream supports cleaning around the gumline and in spaces that are difficult for bristles to enter directly. This coordinated approach helps users maintain a thorough routine without feeling that they need to press harder.

Deep-cleaning performance, designed for daily use

A comfortable brush still has to deliver a convincing clean. According to the product brochure, the AirJet technical platform achieved Level 1 cleaning efficiency under certificate CVC24300012089 and a 97% plaque-removal rate in the stated test. The key is not a single burst of power, but the way airflow, microbubbles, toothpaste foam and precision bristles work together across the tooth surface.

A new kind of clean

AirJet Technology represents a shift in electric brushing—from cleaning by motion alone to cleaning through controlled airflow, fluid dynamics and precision contact. For users who want their teeth to feel exceptionally clean without making gums feel punished, it offers a more considered path forward.
