FAQs

Why do you need to use a UV bottle purifier?

There are various reasons why a UV bottle purifier is essential. For one, it destroys bacteria, viruses, and mold that cause odor and illnesses. As such, you can be assured of clean drinking water that’s safe from waterborne diseases. They are also reusable, which means you won't need to damp after use, hence eco-friendly. Lastly, they have been designed to last long, so you save money in the long run.

How do you use a UV bottle purifier?

For most UV-C purifier bottles, the cap emits a wavelength of radiation to deactivate any living organisms in the water. Therefore, you start by filling the bottle with your liquid, screw the lid, and tap the power button (usually located at the top of the cap). Thus starts the purification process for about 60-120 seconds for most bottles.

Is a UV bottle purifier safe to use?

UV water treatment is safe. Although UV-C light is harmful to humans, it does not alter the composition of water. Unless you look at the light when it’s on, UV light bottles are safe to use. Besides, most caps do not work when they are not screwed even if you accidentally pressed the button.

How long does a UV bottle purifier take to sterilize water?

UV light bottles differ when it comes to purification processes depending on the source of water. It takes more time to clean water from questionable sources like lakes than it takes to clean regular tap water. Most of them will have two cycles: the normal cycle to clean regular water and the secondary cycle to purify dirtier water. The cycles range between 60 to 120 seconds, depending on the source.
