But sometimes, you just want to get the safest kind of water to drink for you or your family; hence, a UV system.

Best UV Light Water Treatment - Our review

Health experts suggest that disinfection is one of the best way to protect yourself against unclean water for consumption. Too many uncertainties and possible contaminants may lurk on other sources aside from municipal water supplies, further reducing the chance that the water is actually safe.

By taking it in your own hands and getting the best UV light water treatment, some risks can be eliminated, giving you peace of mind.

How Does UV Light Water Treatment Work?

UV, or ultraviolet radiation, is a band of energy within the electromagnetic spectrum. A UV light’s wavelength is proven to be effective in eliminating germs thriving in water.

UV is among the many types of water purification process available for consumers. UV light cleans out only the harmful microorganisms found in drinking water, and it does not change the water in any way, preserving the original taste and clean odor. Other treatment processes such as chlorination will change the taste and odor, with possible creation of chemical byproducts such as haloacetic acid and trihalomethanes.

Ultraviolet light water treatment works because it inactivates the organisms by destroying their very DNA. Doing this prevents them from replicating and being harmful. Note that while chlorine kills bacteria, UV deactivates them with its 254nm wavelength, which is easily absorbed by the microorganism’s genetic material. In simple terms, the bacteria get neutered.

UV Light Treatment Advantages

1. No Added Chemicals. In fact, there’s no harmful chemicals of any kind, period. You won’t need to store them, handle them in treating your drinking water or add them in. You won’t pollute or harm the environment in any way.

2. No Byproducts. UV treatment does not alter water and its composition. Companies use this type of water treatment for food processing applications and bottling plants because it is safe.

3. Cost Efficient. Compare the cost of treating drinking water with chemical and UV systems, and you will see that UV comes out on top. The actual electrical costs of running a UV light water treatment is just the same as using a regular light bulb.

4. Fast-Acting. UV light is faster when it comes to treating water to be safe for drinking. It is much more effective in a broader range of microorganisms, too.

5. Low Maintenance. UV systems are unobtrusive and they don’t require too much space. They can be installed by homeowners and the maintenance is almost negligible.
