You should consider six important factors when choosing a UV-powered water bottle: Purification, taste, design, ease of use, capacity and battery life. If you decide to purchase a self-cleaning water bottle, you’ll want one that kills as many microbes as possible, produces a good taste, is easy to hold and transport, and lasts for a decent period of time on one charge.
1. Purification: What does the bottle promise to get rid of, and at what percentage? Also, how long does it take for the bottle to purify the water? Is there an auto-clean function? I also considered how the bottle smelled and looked on the inside after three days of use.
2. Taste: How does the water taste after going through the purification cycle, compared to my drinking water?
3. Design: What is the bottle made of and how convenient and easy is it to carry around? Does it keep water cold?
4. Ease of use: How easy is it to set up the bottle for first use, clean it and store it?
5. Capacity: How much water does the bottle hold? Will you be refilling it constantly, or will the pure water last you a while?
6. Battery life: How long does the bottle last (and how many cleaning cycles can it complete) on a full charge?
