Top 10 FAQs about how the Voxpure Smart Water Bottle works.

What makes a smart water bottle? If you’ve ever wondered how a sleek stainless steel bottle can purify your water, tell the temperature, or remind you to stay hydrated — you’re not alone. At Voxpure, we get a lot of questions about the technology inside our UV-C smart bottle.

1. What exactly is Smart UV-C water purification?

UV-C is a specific range of ultraviolet light (between 260–280nm) known for its germ-killing abilities. In the Voxpure bottle, this light is emitted from a high-efficiency LED inside the cap and runs a 180-second cycle to neutralize up to 99.99% of bacteria and viruses — no filters, no chemicals.

2. How do I activate the sterilization feature on a smart water bottle?

Touch the screen to wake it. Then press and hold for two seconds. You’ll see a blue ring and a countdown from 180 seconds. That’s your purification cycle in action. It shuts off automatically when finished.

3. Is a smart water bottle safe to use with hot water?

Voxpure detects temperature and adapts. However, UV sterilization won’t activate if the water is above 60°C — a safety feature to protect internal components. For hot beverages, the bottle still insulates, but skips the UV cycle.

4. How long does the battery last?

A full charge takes around 3 hours and supports up to 60 sterilization cycles. That’s about two months of daily use. The LED indicator ring flashes red while charging.

5. What does the LED ring mean on the Voxpure smart water bottle?

The ring changes color based on temperature and function:

• Light blue: cool (0–36°C)

• Green: moderate (37–60°C)

• Red: hot (61–99°C)

• Flashing red: charging

• Blue: UV sterilization

• Green: hydration reminder alert

  
  

6. How does the hydration reminder work?

Double-tap the screen to activate a 90-minute timer. After 90 minutes, the bottle beeps and flashes yellow to remind you to drink. It’ll do this four times before auto-off — great for staying on top of hydration during long workdays or hikes.

7. What materials is it made from?

The inner layer is SUS316 stainless steel, chosen for its resistance to corrosion and water purity. The outer layer is SUS304, giving the bottle strength and sleek style. It's fully leakproof and weighs under 500g.

8. Can I take the Voxpure smart water bottle on a plane?

Absolutely. Voxpure is travel-ready. It’s under carry-on liquid limits when empty, leakproof, and doesn’t rely on Wi-Fi or apps — just smart tech in a bottle. Perfect for unpredictable tap water while abroad.

9. Will it work in cold weather?

Yes. Whether you’re skiing, hiking, or just commuting in winter, the vacuum insulation keeps drinks cold for 24 hours or hot for 12. The temperature display makes it easy to check your drink status at a glance.

10. Do I need to replace any parts?

Nope. That’s one of the best parts of Voxpure. Unlike filters that degrade or need changing, UV-C light remains effective long-term. Just recharge via USB-C — no ongoing costs, no extra waste.
