That is why self-cleaning water bottles are beginning to appear. This can reduce the amount of effort and time that needs to be put in when cleaning a water bottle. A lot of companies have realized they can use ultraviolet (UV) light to clean water bottles. Continue reading to find out more about self-cleaning water bottles and why they’re worth it. 

What Is a UV Light Bottle?

What Is a UV Light Bottle?

A UV light water bottle contains a UV-C light bulb on the top of the lid. The UV light is supposed to kill odor-causing bacteria while helping to clean the inside of the bottle. The CRAZYCAP 2 filtered water bottle is a great option because it allows the user to clean the contents of the water bottle easily and effectively. 

With just two taps on the lid, the UV light is activated for a quick clean that lasts two minutes. Otherwise, tap the lid five times and receive a deeper purification process that takes two minutes. On top of this, UV light automatically activates every four hours, so the water is always clean and fresh. 

How Does It Work?

How Does It Work?

There are three main types of UV light; UV-A, UV-B, and UV-C. The light that is used to kill bacteria and viruses is UV-C because it has the shortest wavelength. This can only happen because UV light can destroy the molecular bonds that hold bacteria together. That is also why many people can find objects that have a UV light, because people have become very hypervigilant when it comes to bacteria. 

UV-C light is trusted because it has also been used to clean surgical equipment in hospitals. The reason being is that it can clean and target areas that are harder to reach when an individual is manually cleaning. 

There have been many gadgets made that use UV light to clean our objects at home. Users are now buying lights for their phones, toothbrushes, and handheld wands to clean their spaces and belongings. Scientists have even been looking at creating UV-C lights to put in public areas, so it is always killing off bacteria and viruses. Using this product is one of the healthy life tips that you should follow.

It can be noted how UV-C light is being used in many places that we already trust. With this in mind, purifying the water that is in bottles, so purified water is consumed is another step towards a healthy lifestyle. 

Is It Safe to Use?

A List of Best UV Light Water Bottles

UV light is used to kill microorganisms, so it is safe in a lot of settings. After placing water into the bottle, the UV light can combat the bacteria and leave you with water that is purified and healthy for you to drink. However, it can also be unsafe to use and may not work. 

In essence, UV light cannot be used if the water is murky, muddy, or has floating debris in it. The reason for this is because it needs to completely and fully penetrate the water with its light for it to kill any bacteria. 

Murky, muddy, and debris-filled water does not allow you to do that. If the water that you have placed in the bottle is not clear, then do not expect the UV light to work properly. 

What to Look for In Your UV Light Self-Cleaning Water Bottle

What to Look for In Your UV Light Self-Cleaning Water Bottle

There are multiple factors to consider before buying a UV light water bottle, but there are five things you should keep note of: purification, design, taste, ease of use, battery life, and capacity. Use this checklist to make sure that you are picking the right self-cleaning water bottle for you. 

  • Purification: What does the UV cleaning water bottle say it can get rid of? What is the percentage of effectiveness the product claims it can use to get rid of bacteria? Also, think about how long it takes for the bottle to purify the water. Is auto cleaning an option with the bottle? After purchasing it, take a look after three days and see if it works and how clean your bottle is. 
  • Design: Look at how the bottle is designed. Is it easy to use? Can you carry it around with no problems? Is a bottle sleeve needed? Does it keep your water cold? 
  • Taste: Compare the UV cleaning water bottle to your normal drinking water and see how it tastes. Does it taste better? Can you taste a difference? Do you want a bottle where you can taste the difference? 
  • Ease of use: Think about if the bottle is easy to use. Can you use it right out of the box? How easy is it to clean manually? Where can you store it? 
  • Battery life: Time how long it takes for it to charge. How long does the charge hold for? Is that with or without additional cleaning for your water? How many cleaning cycles does it complete on one charge? 
  • Capacity: What is the UV light water bottle capacity? Does it need to be refilled often or are you able to keep it with you for long periods of time? 

These five things are great to think about before purchasing a UV cleaning water bottle. At the end of the day, this is an investment into an object that is supposed to give you clean and purified water. Make sure that it is right for you and think critically about it. Do not waste your money on a water bottle that you may not even use.
