UV-C purification
Your water bottle is a bacteria trap.
Refill after refill, your reusable bottle grows a film of bacteria and mold in every spot a sponge can't reach — the threads, the cap, the bottom. That's the slime you feel and the smell you can't scrub out.
Most of us rarely wash a bottle properly between uses, so we drink right out of it anyway.

Clean water and a clean bottle — at the push of a button.
A UV-C LED built into the base runs a 60-second cycle that breaks down the DNA of bacteria in your water and on the inside of the bottle, so they can't multiply or make you sick — the same germicidal light hospitals and water treatment plants trust.
Use it daily and buildup never gets a foothold: no slime, no odor, no hand-washing — and no chemicals or taste change in your water.

In an independent laboratory time-kill study, Luma's UV-C cycle eliminated up to 99.99% of E. coli in the water and on the inside of the bottle. UV-C is an EPA- and WHO-recognized method for disinfecting water — chemical-free, and safe to drink right after.
Independently lab-tested in a time-kill study on E. coli. UV-C purifies — it is not a water filter and does not remove sediment, metals, or chemicals.

Frequently asked questions
How does the Luma UV water bottle purify water?
The Luma Bottle is a 20-ounce water bottle with built-in UV-C light technology. At the push of a button, the UV-C LED activates and kills bacteria inside both the water and the bottle itself. The UV-C light destroys the DNA of waterborne microorganisms, preventing them from reproducing or harming you and effectively sanitizing your water. This provides chemical-free purification without altering the taste or adding any substances to your drinking water.
Is the Luma water bottle BPA-free?
Yes. Built tough using BPA-free materials, the Luma holds up day after day without harming your health or the planet. Since certain plastics contain Bisphenol A - a substance known to seep into drinks - the absence of it here keeps your water safe from unwanted chemicals. With every sip of UV-C treated liquid, there is peace in knowing the container adds nothing risky to what you consume.
Can a UV water bottle replace a water filter?
UV purification and water filtration serve different purposes. Tiny invaders such as bacteria, viruses, and other microscopic life get wiped out by UV-C rays. Yet those rays do nothing about visible gunk - stuff like rust flakes, lead bits, bleach residue, or industrial runoff. Filters take care of that kind of junk, trapping it inside porous barriers. Most city water arrives pre-disinfected at your faucet, so adding UV means extra safety against unseen bugs. When the source seems sketchy - a lake, well, or roadside spring - slap a filter on first, then hit it with UV. Together, they cover nearly every threat lurking in liquid form.
How long does the Luma bottle battery last?
The Luma features a rechargeable battery that supports multiple UV-C purification cycles between charges. It's designed for daily on-the-go use, at the gym, on hikes, at the office, and during travel. Recharge via USB between uses. The bottle is sized at 20 ounces, which provides a practical hydration volume for most daily activities while remaining portable and easy to carry.
Is UV-C purified water safe to drink?
For sure, the EPA along with the WHO backs UV-C as a reliable way to sanitize water. Big city systems and bottle makers have relied on it for years. Shining UV-C light kills germs but leaves behind no added substances or odd flavors. This sanitizing process wraps up fast - water can be drunk right after, nothing lingers. No hold time needed once it's done.
