The Electric Toothbrush That “Sprays” Air: RANVOO Unveils Its Jet-Powered AirJet™ Toothbrush

Ditching friction for high-pressure airflow and microbubbles, RANVOO’s AirJet™ platform redefines how the world brushes

An electric toothbrush that cleans with a jet of air is now a reality. RANVOO, the global personal-care technology brand, today announced the launch of its jet-powered AirJet™ electric toothbrush series — marking the arrival of a genuinely new category in oral care built on non-contact, airflow-assisted cleaning.

Unlike conventional electric toothbrushes that rely on high-frequency bristle friction, AirJet™ technology brings pressurized airflow and cavitation microbubbles into everyday brushing — shifting the cleaning action from “scrub harder” to “spray smarter” while dramatically reducing physical impact on the gums.

The innovation grew out of a simple question the industry had ignored for decades: why should cleaning your teeth have to hurt?

Laboratory-Grade Pneumatics, Now in Your Hand: The AirJet™ System

The heart of AirJet™ is a feat of miniaturization: pneumatic engineering that once required desktop-scale laboratory equipment, now integrated into a handheld toothbrush. The full system works in five stages:

  1. Filtered intake — Air enters through a filtered port at the base of the handle.
  2. High-pressure compression — A miniaturized, variable-frequency, three-cylinder air pump pressurizes the airflow.
  3. Cavitation — A boost chamber amplifies pressure, generating dense cavitation microbubbles in the water and toothpaste foam.
  4. Fluid guidance — Coanda-effect brush-head geometry shapes and accelerates the stream into a concentrated jet, aimed precisely at tooth surfaces and interdental spaces.
  5. Microbubble collapse — The microbubbles travel into narrow gaps along the gumline and between teeth, then collapse — releasing pulses of energy that dislodge plaque without bristles scraping the gums.

RANVOO’s internal laboratory reports that, compared with conventional electric toothbrushes, the AirJet™ system delivers a 97% plaque-removal rate while reducing working frequency by 39%, physical applied force by 56%, and composite gum-damage rate by 90% — less than one-tenth that of conventional electric brushes. Cleaning efficiency is also independently validated by a CVC Cleaning Effect Classification Level 1 certificate (No. CVC24300012089, valid through February 2029).

First in the Jet-Powered Lineup: AirJet™ X5 and AirJet™ X3

RANVOO’s jet-powered series launches with two models:

AirJet™ X5 — The Flagship. Built around the AirJet™ 2.0 system, the X5 features a full-screen dynamic display, five cleaning modes (AirJet™, Gentle, Clean, Whiten, and Travel Lock), a compact brush head engineered to reach the last molar, a 12-degree micro-sweep, and a magnetic wall-mounted charging dock. With IPX7 water resistance and up to 60 days of battery life on a single charge, it delivers deep cleaning with gum-friendly comfort at home and on the go.

AirJet™ X3 — The Youth Specialist. Designed for ages 8–14, the X3 pairs the AirJet™ engine with a small round brush head, fluoride-infused bristles for cavity prevention, and low-amplitude micro-sweeping tuned for developing gums — supporting daily cleaning and proactive cavity prevention for younger users.

Both models feature DuPont Pro-grade diamond bristles with 0.01 mm tapered tips and a 99.9% taper rate, seated in a fully rubber-wrapped brush-head base — a design philosophy that prioritizes gum comfort in every detail.

From “Brushing Harder” to “Spraying Smarter”

“For 50 years, the electric toothbrush industry competed on vibration frequency — while overlooking the real problem: cleaning shouldn’t come at the cost of your gums,” said a RANVOO spokesperson. “AirJet™ is our answer. By completing the cleaning with high-pressure airflow and microbubbles, we’ve moved brushing from mechanical friction to fluid dynamics.”

With the launch of its jet-powered toothbrushes, RANVOO is accelerating its global expansion. The brand’s products now reach 128+ countries and regions, serving more than 100 million cumulative users worldwide. The company also confirmed that an all-new electric toothbrush will be unveiled this October, further expanding the potential of the AirJet™ platform — stay tuned.
