When purchasing an electric toothbrush or other oral care products, one of the most important factors to consider is the waterproof rating. Understanding IPX4, IPX7 and IPX8 ratings can help you choose durable, safe, and high‑performance devices for your OEM/ODM brand.
What Do Waterproof Ratings Mean?
Waterproof ratings (Ingress Protection or “IP” ratings) measure how well a device is protected against solids (first digit) and liquids (second digit). For electric toothbrushes, the second digit is key—it tells you how much water exposure the product can withstand in wet environments like the bathroom.
Common Waterproof Ratings for Electric Toothbrushes
IPX4: Splash‑Resistant from Any Direction
An IPX4 rating means the device can handle splashes but should not be submerged. Ideal for quick rinses under a tap, but avoid full immersion.
IPX7: Submersible up to 1 Meter for 30 Minutes
IPX7‑rated toothbrushes can be submerged to 1 m (3.3 ft) for up to 30 minutes. Perfect for use in the shower and for thorough cleaning without risk of internal damage.
| Waterproof Rating | Description | Suitable for |
|---|---|---|
| IPX4 | Splash‑resistant from any direction; can withstand accidental splashes. | Everyday use; rinsing under running water; not submersible. |
| IPX7 | Can be submerged in water up to 1 meter (3.3 feet) for 30 minutes. | Use in the shower; can be rinsed off easily under running water; safe for submersion. |
| IPX8 | Can be continuously submerged beyond 1 meter, typically up to 2 meters. | High‑end waterproof products; ideal for continuous wet conditions; professional‑grade products. |
IPX8: Continuous Submersion Beyond 1 Meter
With an IPX8 rating, devices endure continuous submersion—often up to 2 m—for extended periods. Recommended for premium models where maximum water protection is required.
Why Waterproof Ratings Matter
- Longevity & Durability: Prevents water damage to internal electronics, extending product lifespan.
- Convenience: Safe for shower use and easy rinsing under running water.
- Safety: Reduces risk of short‑circuits and electrical hazards.
- Versatility: Ideal for travel and varied environments.
How to Choose the Right Rating for Your Brand
- Usage Environment: If frequent shower use is expected, choose IPX7 or IPX8.
- Budget Considerations: IPX4 models are more affordable and adequate for basic splash resistance.
- Manufacturer Reputation: Partner with brands that clearly certify their IP ratings and meet industry standards.
