At HAIDU, simplifying self-care is our core mission. We help people improve their health, save time, and feel confident in their daily routines. Whether it's ear care, oral hygiene, or nasal health, our products are developed based on scientific research, medical collaboration, and extensive user testing. But what truly sets HAIDU apart? In this blog, we reveal the scientific and quality-driven foundation of our product development.

Based on clinically proven principles

Every HAIDU product is inspired by medical standards and evidence-based techniques. Our nasal rinsers and ear cleaners, for example, follow internationally recognized methods for irrigation and hygiene. Nasal rinsing with isotonic saline is recommended by organizations such as the American Academy of Otolaryngology and the Dutch Society for ENT Medicine for its effectiveness against congestion, allergies, and infections.

For ear care, we support the advice of ENT specialists to avoid cotton swabs and instead use safe irrigation techniques. That’s why our HAIDU Pro Plus and Pro ear cleaners feature controlled water pressure, soft silicone tips, and—in the case of the Pro—a built-in camera for visual guidance.

In oral care, we build on the proven value of daily interdental cleaning and sonic technology. Our 3-in-1 electric toothbrushes combine brushing, flossing, and rinsing in one device. The HAIDU Electric Flosser was specially developed to precisely clean where water flossers sometimes fall short.

Collaboration with medical professionals

HAIDU actively collaborates with doctors, dentists, and ENT specialists during product development. We have prototypes tested by medical experts and incorporate their feedback into every design, whether it’s optimizing water pressure in flossers, improving the ergonomic shape of ear tools, or perfecting saline formulations for nasal rinsing.

Quality, safety and sustainability

At HAIDU, we uphold strict quality standards. Our products are made from durable materials such as medical-grade silicone, BPA-free plastics, and stainless steel. Each product is CE-certified and undergoes quality control in certified production facilities.

• Water flossers: with multiple pressure settings, antibacterial tips, and long battery life.
