Top 6 Best UV Bottle Purifiers in 2022

by FrankJun 18th, 20228 mins read

We have recently begun to understand the need for sterilizing devices to kill any germs in our environment and stay safe from the spread of infectious diseases.

That's why you need to think about getting yourself a bottle with a UV-C lights purifier to keep your drinking water clean at home and in outdoor areas. UV-C bottles are quick at purifying water, whether from your tap, a pond, or other questionable sources. Besides, they are self-cleaning, which means you don't have to worry about soaps and chemicals for you or even the babies.

Furthermore, UV-C self-cleaning water bottles are easy on the environment, unlike disposable plastic bottles that are detrimental to our ecosystem. You can use a UV-C bottle again and again while reducing your waste footprint. They are an excellent acquisition for traveling and camping because most are rechargeable and the battery can last for weeks.

Difference between filtered water and self-cleaning water Filtered water is water that has been passed through a filter to remove impurities. Self-cleaning water is water that has been treated with UV-C light to kill bacteria, viruses, and mold. Both types of water are safe to drink, but self-cleaning water is more effective at removing impurities.

Environment Protection One of the significant advantages of self-sanitizing water bottles is that they are reusable. It would help if you did not throw them away after using them once. Also, most of these water bottles come with a replaceable filter, which means you can use them for an extended period. The reusable water bottles are eco-friendly and can save you money in the long run.

Do you need the best bottle sterilizers to have purified water at all times? Read this article as we discuss the six bottles on the market, depending on your needs.

Why do you need to use a UV light bottle purifier?

There are various reasons why a UV water purifier is essential. For one, it kills 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 self-cleaning water 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. UV light bottles are safe to use unless you look at the light when it's on. 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 second cycle to purify dirtier water. The cycles range between 60 to 120 seconds, depending on the source.

Is it worth buying self-sanitizing water bottles?

Yes, it is. A UV-powered water bottle is a handy tool, whether you're traveling or hiking. It comes in handy when you can't find clean drinking water, and you need to drink from questionable sources like lakes and rivers.

Does it work at all temperatures of water?

UV is not temperature-sensitive, and it will work just as well at cold or hot temperatures. However, we recommend using water that's room temperature or cooler for best results.

Safe for baby to drink?

Yes, most of these water bottles are safe for babies to drink from. The UV-C light used in these bottles is not harmful to humans. However, we recommend that you use water that's room temperature or cooler for best results.

Final Thoughts

Self-sanitizing water bottles are a handy tool to have when you're traveling or hiking and can't find clean drinking water. They use UV light to kill any bacteria, viruses, or mold in the water, making it safe to drink. Most of them take between 60 and 120 seconds to purify the water, so they're quick and easy to use.
