No, since the LARQ Bottle does not contain a filter, it does not remove physical impurities from the water. The UV-C LED technology is effective in eradicating up to 99.9999% of harmful bacteria, mold and viruses in Adventure Mode–preventing the growth of odor-causing bacteria and eliminating water-born illnesses.
Can I put other beverages in there besides water?
The LARQ Bottle is designed as a self-cleaning bottle for water. We do not recommend using it for other beverages. If you do end up putting sugary drinks, tea or coffee in your bottle, hand wash it after each use with warm soapy water.

For the LARQ Bottle, the fill line is approximately the middle of the top portion of the LARQ Bottle (indicated as #4 in the diagram), just below where the curve begins.
How does Self-Cleaning Mode work? How can I tell?
Self-Cleaning Mode will activate every two hours from the last cleaning cycle for ten seconds (indicated by a blue breathing light). It is a very quick cycle, so it is easy to miss!
Also check if your LARQ Bottle is in Travel Mode, which will lock the LARQ Bottle so that the Self-Cleaning Mode is turned off. To turn Travel Mode off and turn on Self-Cleaning Mode, press and hold the cap for 5- 10 seconds until a white light turns on and flashes.
Can I put ice in my LARQ Bottle?
Ice is completely fine to use with the LARQ bottle, and will not damage the bottle itself in any way. However, it may impact the efficiency of the UV-C LED since LARQ uses a line of sight technology and the ice may prohibit the UV-C LED from reaching certain areas of the bottle when solid.
Can I use alkaline water in my LARQ Bottle?
Yes, you can put alkaline water in the LARQ Bottle and it should not impact the efficacy of the UV-C LED technology, nor will it impact the mineral or acid levels in alkaline water.
How do I activate a cleaning cycle?
Press the LARQ Bottle cap once to activate it and in 60 seconds you'll have pure water to drink.
Can I put hot water in the LARQ Bottle Movement?
The LARQ Bottle Movement has a single-wall non-insulated construction. Although the cap can handle most temperatures, the bottle itself may get hot if handled with hotter liquids. We recommend using the LARQ Bottle Movement with cold to warm water only. If you prefer to drink hot water, try the LARQ Bottle–our double-wall vacuum insulated model that will keep liquids cold for up to 24 hours and hot for up to 12 hours!
How is the LARQ Bottle Movement different from the LARQ Bottle?
Both LARQ Bottle and LARQ Bottle Movement collections use the same cap and proprietary UV-C LED technology. The difference between them is in the design, water capacity, weight, and construction of the bottles.
The LARQ Bottle features double-wall vacuum insulation that keeps your water hot for 12 hours and cold for 24 hours. It also features our two-tone proprietary powder coating and Red Dot award-winning design. Visit our LARQ Bottle page to learn more.
The LARQ Bottle Movement is a lighter weight bottle due to its single-wall construction–perfect for staying hydrated while backpacking or commuting–and features a silicone sleeve that protects the bottle from bumps and knicks (for the perpetually clumsy). Visit our LARQ Bottle Movement page to learn more.
What happens to the germs and bacteria in the water or bottle? Is it filtered out?
The LARQ Bottle is a water purification system. UV-C light is blasted at 280 nanometers inside the bottle when your cap is activated to break down bacteria and viruses at the DNA level, rendering them inactive and preventing potential growth, making your water safe for consumption. The LARQ Bottle is not a filter and does not remove any physical particles from the water. To learn more about how UV-C LED works, check out our Technology Page.
Technology
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. Learn more on our Technology Page.
Does the LARQ Bottle remove heavy metals or fluoride?
No, since the LARQ Bottle does not contain a filter, it does not remove physical impurities from the water. The UV-C LED technology is effective in eradicating up to 99.9999% of harmful bacteria, mold and viruses in Adventure Mode–preventing the growth of odor-causing bacteria and eliminating water-born illnesses.
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 inside of the bottle. The UV-C light eradicates biological contaminants by destroying their DNA.
What is UV-C LED technology?
The UV-C wavelength emitted from the UV-C LED located in the LARQ Bottle Caps are optimized at the 280 nanometer spectrum to eliminate up to 99.9999% of bacteria and viruses by breaking down their DNA before they have a chance to spread, making the water pure and safe to drink. At the minimum, the LARQ Bottle should be filled with water that is clear to the eyes and does not contain any physical sediment as the UV-C LED will not remove these impurities from the water. The UV-C LED chip in the LARQ Bottle are smaller, more energy efficient, non-toxic (mercury-free), and more economical compared to traditional Mercury-based UV technology.
Is the LARQ Bottle safe to use?
Yes, the LARQ Bottle is safe. UV-C LED light does not remain in the water and therefore is perfectly safe for consumption.
The LARQ Bottle does have a Safety Mode, which is indicated by a flashing orange light that prevents accidental activation when the cap is not on the bottle by dimming the UV-C LED light. One should never place the activated UV-C LED in direct contact with the skin or eyes.
The Uses
Is the LARQ Bottle refrigerator/microwave/dishwasher safe?
The LARQ Bottle may be refrigerated but bear in mind the double-wall vacuum insulated feature of this bottle will not allow contents inside to be affected by external temperatures.
The LARQ Bottle Movement may be refrigerated to keep the contents cold due to its single-wall stainless steel construction.
Do not put any of our LARQ Bottles in the freezer, microwave, or dishwasher.
Can I fly with my LARQ Bottle?
Yes, it will have no problem coming along with you on flights as long as you empty out all the liquids from the bottle. The LARQ Bottle and LARQ Bottle Movement should be kept on your person or in your carry-on. It may not be transported in a checked bag due to the Li-polymer battery in the cap.
Can I clean the LARQ Bottle/LARQ Bottle Movement?
The LARQ Bottle and LARQ Bottle Movement are 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 and wiping the mouth area from time to time.
Can I put other beverages in there besides water?
The LARQ Bottle is designed as a self-cleaning bottle for water. We do not recommend using it for other beverages. If you do end up putting sugary drinks, tea or coffee in your bottle, hand wash it after each use with warm soapy water.
Can I use the LARQ Bottle/LARQ Bottle Movement in the backcountry or while traveling?
Yes! Our UV-C LED technology will eliminate 99.9999% of germs, bacteria, and viruses in Adventure Mode. It will not remove heavy metals or chemicals in the water. It will depend on the region that you are in as to which contaminants exist in the water, so it may be advised to take additional precautionary methods with any LARQ Bottle depending on the water source to ensure the safety of the water.
Can I put fruits in the LARQ Bottle? What will happen?
Fruit is fine to use with the LARQ bottle, and will not damage the bottle itself in any way nor will the UV-C LED technology affect the fruit. However, it may impact the efficiency of the UV-C LED since LARQ uses a line-of-sight technology and the fruit may prohibit the UV-C LED from reaching certain areas of the bottle. We would recommend washing the LARQ Bottle with warm soap and water if used with fruit.
How clean must the water be?
At a minimum, it should be clear to the eye with no heavy sediment.
