LARQ

The innovators at LARQ have created the world's first self-cleaning water bottle by utilising the power of a UV-C light hidden in the cap. This is their PureVis technology. Every two hours, your LARQ bottle activates, eliminating bacteria that might be growing inside your bottle. This leads to better tasting, healthier and less stinky drinks all day.


Biome currently stocks two types of LARQ Bottles, both featuring PureVis UV-C lids.

The first is the 500mL Insulated style. This can keep liquids hot for up to 12 hours and cold for up to 24 hours, which is pretty impressive and outperforms many other premium insulated bottles.

We also stock the 710mL Movement style. The Movement style is not insulated, allowing the bottle to hold more water in a bottle that is basically the same size as the insulated version. Additionally, it is lighter than the insulated style.

Frequently Asked Questions.

  1. What's in the box?
    PureVis LARQ water bottles include the bottle, a USB charging cable and a Quick Start Guide. Everything you need to get purifying ASAP!
  2. How does LARQ PureVis work?
    The PureVis UV-C light activates at the touch of a button. Additionally, the bottle can be set to activate once every two hours, for constantly fresh water. The PureVis cap features Normal, Travel & Adventure modes.
  3. Are Self Cleaning Bottles Safe? 
    PureVis is LARQ's name for the UV-C disinfectant LED that is in the cap of their bottles. The LED emits safe wavelengths between 270 & 275 nanometers, perfect for eliminating up to 99% of bio-contaminants by breaking down their DNA. To allow for maximum safety, you should fill your LARQ with water that is at least clear to the eyes and free of any sediment or visible dirt particles, as these cannot be removed by UV light. For this purpose, a Water Filter Bottle may be more appropriate. Compared to traditional mercury-based UV technology, the PureVis LED tech is smaller, more energy efficient, non-toxic and more economical.
  4. How do I charge the PureVis cap?
    The PureVis cap can be recharged with the included chord via the charging port located in the cap.
  5. What is the difference between Normal, Adventure & Travel modes?
    Normal Mode is activated by a single tap of the cap button and designed for use when the water is from a trustworthy source. It features a one-minute cleaning cycle that sheds 12mJ/cm2 of UV-C light on the water and interior surface of the bottle.
    Adventure Mode is a three-minute cleaning cycle designed for use when the water quality is unknown. Activate it with a double-tap. It provides at least 30mJ/cm2 of UV-C light for purification.
    Travel Mode is designed to prevent accidental activations while your LARQ bottle is in your bag or empty. Extra activations are not really necessary and cause the battery to run down. It is turned on and off by holding the button for 5-10 seconds.
  6. What's the go with Self-Cleaning Mode?
    Provided your bottle is not in Travel mode, the PureVis cap will automatically activate every two hours for a 10 second cycle. This is a quick cycle designed to maintain the freshness of your water after the initial blast it got when first filled.
  7. How often does the PureVis cap need to be charged?
    If you activate the bottle 3-4 times per day in Normal mode, the cap's battery will last for about a month. In Adventure Mode, the battery will last up to 12 days. You can tell when the bottle needs charging as the cap light will blink yellow at the beginning & end of cleaning cycles.
  8. What do the cap light colours mean?
    The PureVis cap features a multi-colour LED light around the outside edge to communicate different functions to you. Here's a breakdown of what they mean:
    Breathing Green: Charging.
    Steady Green: Fully Charged.
    Breathing Sky Blue: Normal Mode.
    Pulsing Blue: Adventure Mode.
    Pulsing Orange: Safety Mode (replace cap before activation OR internals are too hot.)
    Steady Yellow: Low on battery. Flashes twice before and after cleaning cycle.
    Red/Purple: Something is wrong. Contact Customer Service.
  9. Will LARQ keep my drinks hot/cold?
    The LARQ Insulated bottles available to buy at Biome feature some impressive insulation. They can keep drinks hot for up to 12 hours or cold for up to 24 hours.
    The LARQ Movement range is non-insulated. This style will not keep drinks hot or cold longer than other single wall stainless bottles. However, not being insulated means the Movement bottles are lighter and more voluminous than their insulated counterparts, in a package that is roughly the same size.
  10. Can I put ice in my LARQ PureVis bottle?
    Ice will not damage your LARQ bottle, but it may impede the distribution of UV-C light around the interior of the bottle. It can be important to take this into consideration depending on your water supply.
  11. Can I put other beverages in my PureVis bottle?
    LARQ PureVis bottles are designed to be used with water. Putting other beverages in there is not recommended. However, if you do, ensure that you thoroughly clean the inside of your bottle ASAP to preserve the efficacy of the UV-C light.
  12. When is it appropriate to rely on the PureVis technology?
    As PureVis is simply utilising light, it cannot remove particulates, such as dirt or heavy metals, from your water. If you are taking the bottle to countries with poor water quality or into the backcountry, ensure the water source looks clear and is free of particulates. Then, let PureVis take care of the bacteria.
  13. Are LARQ PureVis bottles appliance safe?
    No LARQ bottles or caps should be put in the microwave.
    The bottle component of PureVis bottles is dishwasher safe, but always hand-wash the cap. Under no circumstances should the cap be placed in the dishwasher.
    LARQ PureVis bottles can be kept in the refrigerator. Keep in the mind that the Insulated variety may not effectively allow the contents to be cooled.
  14. Can LARQ PureVis bottles be taken on planes?
    You must bring the bottles with you in carry-on luggage due to the Li-polymer battery that powers the UV-C light. Remember that airport security often requires containers larger than 100mL to be empty.
  15. How do I properly clean my PureVis bottle?
    As mentioned earlier, LARQ PureVis bottles do not need to be cleaned as frequently as normal water bottles. However, every few weeks, it is a good idea to thoroughly clean the bottle.   See more here on How to Clean a Water Bottle.
