Question 1

Can I screw the cap onto other standard water bottles?

Accepted Answer

No, the cap is designed specifically for LARQ's Movement bottle threading, which is non-standard. You cannot use it on other brand bottles.

Question 2

How do I know when the UV bulb needs replacing?

Accepted Answer

The UV-LED is rated for over 10,000 hours of use (about 1 year of typical household use). The cap does not have an indicator, but LARQ recommends replacing the cap assembly every 12–18 months. You can purchase replacement caps separately.

Question 3

Does the UV light reach all the water if the bottle is full?

Accepted Answer

Yes, the UV-C LED is designed to penetrate clear water up to about 24 inches (the bottle is ~10 inches tall). The light reflects off the stainless steel walls, ensuring all water gets exposed. However, murky water can block UV, so it works best with clear tap water.

Question 4

Does the UV cleaning cycle use much battery?

Accepted Answer

A single 60-second cleaning cycle consumes about 0.5% of battery capacity. The automatic sensor (which activates when you tilt the bottle) uses a small amount of power as well. The largest drain is the UV cycle, not the sensor.

Question 5

Is the LARQ Bottle Movement BPA-free?

Accepted Answer

Yes, the bottle body is 304 stainless steel and the cap is made from BPA-free polypropylene and food-grade silicone. The UV lens is quartz glass.

Question 6

Does the bottle leak?

Accepted Answer

Most users report no leaking when the cap is fully closed and the silicone seal is intact. Some have experienced minor leaks after dropping the bottle, likely due to the seal shifting. LARQ provides replacement seals.

Question 7

Can I use the LARQ Movement with lemon or cucumber slices?

Accepted Answer

LARQ advises against adding anything but plain water. Fruit slices can block the UV light and reduce effectiveness, and they may also leave residue that can promote bacterial growth even after cleaning.

Question 8

Can I leave water in the bottle for days without cleaning?

Accepted Answer

While the UV cycle kills microbes, if you leave water for multiple days, it can still become stale due to dissolved gases and potential biofilm buildup. LARQ recommends running a clean cycle every 48 hours if not using the bottle, and washing the body regularly.
