The inner surface of the LARQ Bottle is electropolished, high-grade stainless steel - this is reflective for UV light and will help channel the disinfecting rays into the corners of the neck as well. Depending on the use case - we do recommend hand washing the mouthpiece from time to time but that should be much easier than playing hand yoga.

The Science

• Has the LARQ Bottle been tested?
  The UV-C LED technology inside LARQ has been tested by independent third-party labs and the LARQ Bottle is effective against E. Coli.
• Where does the filtered stuff go?
  The UV-C LED breaks up bacteria DNA, so it becomes harmless organic material. The bottle will turn-on automatically every 2 hours – the bacteria or other bio-contaminants never have a chance to develop in the first place.
• Does the LARQ Bottle remove heavy metals or fluoride?
  No, it does not but it does eradicate 99.9999% of harmful bacteria, mold and viruses in Adventure Mode. It also keeps your bottle free of harmful and odor causing germs.
• How does the LARQ Bottle work?
  The LARQ Bottle uses patented UV-C technology to purify your water and bottle at the touch of a button. The bottle intelligently turns on every 2 hours to purify both the water you put inside as well as the bottle surface itself. The UV-C light eradicates biological contaminants by destroying their DNA.
• What is UV-C LED technology?
  The UV-C LED chips in LARQ are smaller, more energy efficient, non-toxic (mercury free), and more economical compared to traditional Mercury based UV technology. The UV-C wavelength is 280 nanometer spectrum that is uniquely suited to eradicate bacteria and germs even before they have a chance to spread.
• Does the LARQ Bottle have any safety measures?
  A safety mechanism in the form of a light sensor prevents accidental activation when the cap is off of the bottle.
• How long will the UV-C Last?
  The LED itself is rated for >100,000 cycles (on/offs) - much more robust than existing Mercury options (typically 8,000 to 10,000 if you read the product data sheets). So depending on your use it should last a very long time.
• Is there efficacy data available on the LARQ Bottle?
  We worked with a third party lab to test the efficacy of LARQ's UV-C LED technology within the application of the LARQ Bottle against water samples enriched with E. coli. You can learn more about the results here.

The Uses

• Can I freeze or refrigerate the LARQ Bottle?
  Yes, you may put the LARQ Bottle in the freezer or refrigerator. However the double vaccum seal will insulate the bottle and its content, meaning the freezer won't be able to cool down the liquid inside efficiently.
• Can I microwave the LARQ Bottle?
  Do not put your LARQ Bottle in the microwave as it will damage your bottle and your microwave.
• Can I fly with my LARQ Bottle?
  The LARQ Bottle is airport security friendly, as long as you remember to empty out what's inside first.
• Can I clean the LARQ Bottle?
  The LARQ Bottle is 10,000 times more hygienic than a normal reusable bottle. You almost never have to clean the bottle if it is used for water. You may need to clean the bottle when you use it for liquids other than water. We recommend gentle hand washing with soap and warm water.
• Can I put other beverages in there besides water?
  Yes, you can but the LARQ Bottle is designed as a self-cleaning bottle for water. If you're putting sugary drinks or coffee in there, the bottle should be hand washed.

  They are designed for everyday use and for camping. We have an "Adventure Mode" to give the UV-C LEDs extra power for when you are travelling abroad or in the backcountry.
• Can I put fruits in the LARQ Bottle? What will happen?
  UV light is actually known to keep fruits fresh such as strawberry. We have not tested for this effect in water but would recommend you replacing the fruits in your water normally.
• How clean must the water be?
  At a minimum, it should be clear to the eye with no heavy sediment.
