LARQ Bottle PureVis 25 oz - Self-Cleaning and Insulated Stainless Steel Water Bottle with UV Water Purifier and Award-winning Design | Reusable & Travel Friendly, Monaco Blue

I love this bottle. I was very scared to purchase a bottle that cost that much, but it is well worth it. I bought it to take on a camping trip that will not have water access to our camp site. I am planning to use it purify water from a stream that will be my water source. It keeps the water ice for a long time. I would recommend purchasing the 24 oz, I seem to go through my water fast, and I have the 24 oz size. It is not the easiest to carry so I purchased the cover made for it, not happy with the cover. overall, I love the bottle and anxious to see how it works on my camping trip

High value performance. I bought this relatively small ultraviolet thermos with traveling in mind and I use it every day and for playing tennis. It works and gives you a little more confidence that what you’re drinking is more pure than without it. I’m very happy with it. It’s in my car cupholder perfectly also.

Putting in my two cents here...UV-C light falls in the only spectrum of UV that can affect DNA replication. The light is enough to stop replication, not completely kill the bacteria. That’s enough for commercial use, both in the UVC wands, phone cleaners, and this water bottle. Why? Cells that do not replicate cannot infect. I do not understand the notion that the light ‘does not kill chemicals secreted by bacteria, which makes you sick’. Bacteria makes you sick. And if you disrupt the dna activity of everything in the bottle, there’s nothing alive that would be harmful.There is no perfect water. Don’t even get me started on how many CFU (coliform forming units- or fecal matter contamination) there is in tap water and bottled water. This water bottle comes pretty darn close to perfect. It doesn’t ‘filter’ so you will occasionally get a metallic taste from various sources- water with lower pH, the metal in water from older pipes. Should be fine as long as there’s not high lead levels. Every city has a water report that tells you the content, including if there’s fluoride (good for you), lead (not good for you).Also a stainless steel container is not one that ‘encourages’ biofilm activity- that would be plastic, which this is not.There are several reviews floating on the interweb from medical ppl doubting that it would work or that UVC light DOES work. As a general rule, don’t side with a camp that makes claims without evidence. Research. Science. “Trust me, I’m a doctor” is only a t-shirt slogan. A good doctor can explain to you why- with both the research done and clinical effects. I’ve never used that phrase and I don’t plan on it.Tl;dr —-The Larq water bottle is great for travelers, nomads, water purists like me. UVC light is proven to de-germ. It does not filter which is generally okay. A little bit of metal is fine, a lot of lead in your city water is not.Please stop upvoting unproven claims.

Mold Can Form Inside This Product!!!!!! I bought this item after seeing it on Shark Tank. I thought it was a great Idea. I needed something in my bathroom to drink water from and brush my teeth. Having a glass in the bathroom is not smart if you knock it over and your in your bare feet. Plastic is an option but not to keen of drinking out of it. Anyway When I bought the Larq it worked great and getting up in the middle of the night and having clean water to drink and in the morning to brush my teeth was good. I always kept it charged and always cycled it when I refilled the unit. One day I had emptied it and looked down inside. Surprise.....MOLD growing at the bottom of the bottle. That was it. I'm not drinking out of that thing again. Someone else mentioned the contacted customer service. I did too. It's been 1 week and no reply. Bad Customer service. Here is the difference between Mold and Bacteria . The Larq was not designed to kill mold. With water left in the unit it is subject to mold growth. Mold and bacteria are both microorganisms, but they belong to different kingdoms and have distinct characteristics. Mold is a type of fungus, while bacteria are single-celled prokaryotic organisms. Mold typically requires high moisture for growth and can be found on decaying organic matter, whereas bacteria can thrive in a wider range of environments, including those that are relatively dry. ...........................So Beware. If you buy this item, Make sure when not in use it is empty and dry and clean inside. Mold Likes damp Climates.

Bought as a gift. They like it a lot. Does what it says it does.

Perfect for what I was looking for

This is a life changing product. Before this product, in any country with questionable tap water, I always relied on bottled water. And while that works, it can sometimes be hard to find, is expensive and bad for the environment. With this bottle, even the most suspect water is drinkable. In Mexico, I tend to use the 60 second cycle. India, the 3 minute cycle, even though they say 60 seconds is enough. I have not tried this on river or lake water, but the independent testing shows it to be effective. Keep in mind, this will not alter the taste of the water (for the most part), but rather just kill off any harmful bacteria to make it drinkable.I also am in love with the design ascetic of the bottle itself. If I had one complaint, they need to update the micro usb port to USB-C. I don't regularly care micro USB cables these days - its a very outdated port and if you forget to pack the one that comes with the bottle, you will not be able to charge the cap if you need to.

We gave this as a birthday gift and our niece loves it. She said the size and color is perfect. Also appreciates how fresh the water tastes and plastic does not come into contact with the water.
