Electric toothbrushes are no longer the novelty they were many years ago. As technology has advanced, more and more people are buying and using them. However, many first-time users often ask: since electric toothbrushes frequently come into contact with water and get dirty easily, can the entire unit be washed under running water? So let’s take a closer look at whether the entire unit can be washed under running water.
1. What is the IPX water resistance rating?
To determine whether an electric toothbrush can be fully submerged in water, we first need to understand the internationally recognized IPX waterproof rating system. IPX ratings are only issued after the product has been tested using specialized equipment. The IPX waterproof rating system consists of eight levels, ranging from IPX-1 to IPX-8. The higher the number, the stronger the waterproof performance.
IPX0: No protection;
IPX1: Drip-proof Type I; vertically falling water droplets have no harmful effect;
IPX2: Drip-proof Type II; no harmful effects from water droplets falling within a 15-degree angle from the vertical;
IPX3: Rain-resistant; no harmful effects from rain falling within a 60-degree angle from the vertical;
IPX4: Splash-proof, protects against water splashes from any direction;
IPX5: Splash-proof, capable of withstanding low-pressure water jets;
IPX6: Water-resistant; withstands high-pressure water jets;
IPX7: Water-resistant; can be submerged in water up to 1 meter deep for 30 minutes
IPX8: Water-resistant; can remain submerged in water under certain pressure for extended periods while still functioning normally;

2. How to Choose an Electric Toothbrush with Strong Water Resistance
When purchasing an electric toothbrush, be sure to check the test report for its water resistance rating first. Generally, household electric toothbrushes have a water resistance rating between IPX5 and IPX7. If the water resistance rating is IPX5 or IPX6, you can rinse the toothbrush lightly, but you should still take extra care to ensure it stays dry. Try to avoid prolonged immersion whenever possible. Higher-end electric toothbrushes on the market generally offer IPX7-level water resistance, and an IPX7-rated electric toothbrush is more than sufficient for daily brushing needs.

Summary: Electric toothbrushes on the market generally have waterproof ratings ranging from IPX5 to IPX7, meaning the entire unit can be rinsed under water. However, for electric toothbrushes with IPX5 and IPX6 ratings, extra care must be taken to ensure they remain waterproof—they should not be submerged.
