1. Deep Interdental Cleaning: Powered by SuperBubble 2.0 technology, the AirJet X5 blasts microbubbles deep into interdental spaces (the gaps between teeth) for a thorough clean, achieving a top-tier cleaning rating and a 97% plaque removal rate.
2. Gum Protection: It delivers a spotless clean using a low-frequency 22,000 vibrations per minute paired with a 12° micro-oscillation, ensuring maximum efficacy without causing gum irritation or damage.
3. Mold-Free Design: The toothbrush body features a nano anti-mold coating and comes with a wall-mounted bracket, keeping your sink area neat, dry, and completely mold-free.

The brand-new AirJet X5 upgrades to our SuperBubble 2.0 technology, delivering 2.4 times the bubble-cleaning power of the previous generation to clear out tight teeth gaps much more effectively. Additionally, we’ve added adjustable bubble intensity levels, real-time timer feedback, a refreshed color palette, and an upgraded smart screen display.

A bubble electric toothbrush utilizes a built-in DC frequency-conversion air pump to generate a high-speed airflow. Utilizing the Coanda effect, the brush head mixes this airflow with fluids in your mouth to create cavitation bubbles. These bubbles penetrate deep into tight interdental spaces that traditional bristles simply cannot reach, leveraging the energy from the collapsing bubbles to burst away stubborn dental plaque and prevent cavities.

The AirJet X5 uses premium US-imported DuPont™ Tynex® Brilliance Pro diamond bristles, which boost cleaning efficiency by 13% and durability by 60%. With normal use, a single brush head lasts up to 120 days (3 months).

Based on brushing twice a day for 2 minutes per session, a single full charge lasts up to 30 days. Furthermore, if you keep the charging cable connected to the wall-mounted bracket, you can just pop it back on after each use for infinite battery life.

That is our Airflow Multiplication Hole. It leverages the Coanda effect to blend oral fluids and air into cavitation bubbles, driving them deep into the gaps between your teeth for a thorough, advanced clean.

Not at all. Gum damage is usually caused by two things: stiff bristles or excessive physical vibration, both of which can irritate the gums and potentially lead to permanent gum recession. The AirJet X5 relies on SuperBubble technology for deep cleaning, meaning we can lower the physical frequency to 22,000 vibrations per minute—the lowest on the market—making it incredibly comfortable and gentle on your gums. Moreover, it is the only brush head on the market featuring ultra-soft bristles with a 99.9% tapered rate, making it absolutely ideal for sensitive teeth.

No, it won't. The entire body of the AirJet X5 is sealed with a full-body nano antibacterial and anti-mold coating, achieving the highest Level 0 mold resistance standard. This is certified by independent third-party laboratory testing, so you can use it with complete peace of mind.
