Which UV-C Water Purification Bottle is Right for You?

Ready to get a UV-C water bottle but not sure how to choose? Here’s how to pick the right UV-C water bottle for you depending on your lifestyle.

Urban Dweller

If you’re looking for a UV-C water bottle to replace bottled water in your daily life in the city, or if you just need to replace your reusable bottle to make it self-cleaning bottle to avoid musty/moldy smell coming from your bottle, then LYT is exactly what you’re looking for. An affordable, lightweight option made for daily usage and self-cleaning purpose. LYT is the perfect water bottle to grab when you’re heading to the office, to the gym, or around town.

The LYT cap has a 10-12mW UV-C LED and kills 99.99% of germs in your water in 3 minutes with a simple click. As LYT is designed keeping urban city life in consideration, it has only one standard mode of purification (i.e., 3 minute), which is more than enough for treating water from city sources. Beside the purification, LYT also offers a pro self-cleaning feature in which UV-C LED turns on every hour automatically for a few seconds to shine the interior of the bottle to prevent the mold and bacterial growth in the bottle. This feature is a key to prevent any growth of bacteria or mold inside of the bottle as a result your bottle smells and remains fresh without having to manually wash them.  All regular bottles need to be washed periodically to ensure no mold or bacteria breeds on the inner surface of the bottle. Typically, this growth happens when the saliva from backwash accumulates on the interior surface of the bottle causing the to smell bad after a few days of usage. With LYT self-cleaning feature, say goodbye to mold and musty smelling bottles. This self-cleaning feature can be turned off to conserve battery especially when you are running low. 

If you already have one of the 17 oz reusable bottles from S'Well, Mira, Simple Modern, Chilly's, etc., then you can just purchase a LYT cap only product instead of the complete unit. LYT complete units come in three sizes 17 oz, 23 oz and 25 oz . LYT 17 oz and 25 oz bottles are made of vacuum insulated 304 stainless steel material which can keep contents cold 12 hrs. and hot 6. Whereas, LYT 23 oz bottle is non-insulated and made up of a BPA-free Tritan plastic and is extremely lightweight making it the perfect bottle especially if weight is your main concern.

LYT has a proprietary port-less magnetic charger, which charges the cap in about two-hour to give 3-4 day battery life. Ideal for everyday usage and urban commute. The LYT magnetic charger is small enough to carry easily with you.
