Larq Bottle ($82, originally $109)
If you're looking for a water bottle that does way more than just hold water, meet your match. This self-cleaning bottle uses UV-C LED technology to purify your water and eliminate odor-causing bacteria. The design is minimalist and travel-friendly, keeping drinks cold for 24 hours (or hot for 12), and the built-in purification system activates with just a tap. Learn more about it in our Larq Self-Cleaning Water Bottle review.
Editor Quote: "Here's what makes this bottle so special: it's self-cleaning. I'll let that sink in for a second before proceeding. If you've ever had a water bottle that does not pass the sniff test, you know what a game changer this is. The bottle also has a purification system within the cap. You can read all about the technology in the bottle here, but the TL;DR version is that it uses UV light to both clean the bottle and purify the water. So if you need to fill your bottle up at a place where you're not confident on the water quality, you'll be happy you have your Larq bottle. Plus, the bottle is insulated, so the water stays cold all night long. I've had mine for a few weeks, and we've been inseparable ever since." — India Yaffe, former associate shopping editor
