It treats the water. You still clean the bottle.

Verdict: Not Verified
Not VerifiedThe short answer: A well-built insulated bottle with a clever UV-C cap. It treats water; it does not clean the bottle you carry, and LARQ's own instructions say so.
- Buy it if
- Travelers who need to treat questionable tap water and understand what UV-C does and does not do.
- Skip it if
- You expected to stop washing your bottle. You will not.
- Best feature
- A well-built insulated bottle with a genuinely clever UV-C cap that runs on a schedule.
- Biggest annoyance
- The cap is not dishwasher safe, the battery is sealed into it, and UV does nothing about residue or flavor.
- The catch
- LARQ's own instructions tell you to hand-wash the bottle regularly. The 'self-cleaning' claim is about the water and the inner surface, not the bottle you carry.

What We Loved
As a bottle it is excellent. The cap is clever.
What Annoyed Us
The 'self-cleaning' name promises a chore removed. The manual tells you to wash it.
The Catch
UV-C affects the water and the inner surface it reaches; it does nothing about residue, flavor or the threads. You will hand-wash it like any bottle.
