TAB
Who are we?
We are tAB, a manufacturing-based company dedicated to public health initiatives. We are the first to invent a cap-type UV sterilizer and have built our business around this innovation. The device can be attached to a variety of containers, addressing a wide range of drinking water hygiene issues. It is primarily used by individuals with compromised immune systems who need safer drinking water. Additionally, because it can be connected to tumblers and military canisters, it is suitable for use in camping gear, baby products, and military supplies.
