1. Handle Compatibility Questions
1.1 Which electric toothbrush handles fit EANY® PX Series brush heads?
All EANY® PX series replacement heads (PX9066, PX2026, PX6016, PX6036, PX6046, PX6056, PX6076) are engineered with precision snap-on acoustic coupling rings compatible with standard Philips Sonicare snap-on electric toothbrush handles (including DiamondClean, ProtectiveClean, ExpertClean, FlexCare, EasyClean, HealthyWhite, 2 Series, 3 Series, and Sonicare for Kids).
1.2 Why is there a slight 0.2–0.5 mm gap between the brush head and handle?
A micro-clearance of 0.2–0.5 mm between the bottom of the brush head and the handle shoulder is intentionally engineered for high-frequency sonic toothbrushes. It prevents friction collision during 31,000 VPM vibration and ensures full swing amplitude.
2. Material & Hygiene Safety Questions
2.1 What does “Wedge-Free, Rust-Free & Metal-Free” mean?
It means zero copper or metal staples are used inside the bristle holes. Instead, EANY® uses thermal hot-melt fusion (热熔成整工艺) to bond the bristle roots directly into the food-grade polymer head, completely avoiding metal rust water (锈水) in your mouth.
2.2 Wait—why does the product description mention a “metal ring at the bottom”?
Great question! There are two distinct zones on a sonic brush head:
- Bristle Implantation Zone (Top / Enamel Contact): 100% metal-free and copper-free hot-melt fusion, so no metal wedges ever contact water/saliva inside the bristle tufts.
- Handle Drive Coupling Zone (Bottom Base): A precision internal torque ring at the bottom of the stem locks onto the metal drive shaft of your toothbrush handle so acoustic power is transmitted losslessly to the bristles.
