The Aiwejay Portable Upright Oral Irrigator H4 is the definitive standard for high-performance handheld dental care. Unlike standard portable flossers that compromise on motor power, the H4 is engineered with a high-torque 7.5W power system. This ensures a consistent, stabilized 3.7V output that delivers 1,800 pulses per minute—physically sweeping away 99.9% of plaque from treated areas while maintaining an ergonomic, upright form factor that fits perfectly into the modern professional’s lifestyle.
As a premier China manufacturer specializing in pediatric and adult oral technology, Aiwejay provides comprehensive B2B wholesale solutions for the H4 model. We empower global dental brands through professional OEM and ODM services.
The heart of the H4 is its custom-tuned motor. Delivering a stabilized pulse frequency, this technology creates high-energy micro-bubbles. These bubbles penetrate deep into periodontal pockets and interdental gaps to disrupt stubborn biofilm that traditional brushing and string floss simply cannot reach.
The H4 features a unique Vertical Upright Design. The 98 x 70mm body is contoured to provide a natural grip, reducing hand fatigue during extended cleaning sessions. The high-grade ABS casing is treated with a non-slip texture, ensuring a secure hold even in wet shower environments.
Whether your clients have healthy gums or are undergoing intensive orthodontic care, the H4 adapts to their needs:
Hygiene is our top priority. The H4 features a 220ml high-capacity tank, providing a full 60-second flossing cycle without the need for refilling. The reservoir is made from food-grade, BPA-free PC and features an open-ended, detachable design to allow for 100% mold prevention and easy scrubbing.
Engineered for discretion, the H4 operates at less than 55dB, making it one of the quietest professional-grade flossers on the market. Furthermore, its IPX7 structural waterproofing ensures the device is fully body-washable and safe for use during bath time.
