The way it works is by allowing water to enter the chamber of the UV housing. Water never touches the lamp itself but moves around a quartz sleeve which protects the water from ever touching the actual lamp.

As the microorganisms get hit by the UV rays, their DNA gets damaged and they become "sterile" and unable to replicate. As they leave the UV housing and enter the home, it's important to understand that these microorganisms are still alive. However, these "sterilized" bacteria and viruses cannot replicate and therefore die over time or by our own body's white blood cells.

When you purchase a UV system, it's important to get proper pretreatment to ensure that the water is as clear as possible to ensure maximum effectiveness. Also, always buy a UV sterilizer that can handle more than your home's flow rate to ensure that your home is protected.

Finally, UV lamps have a life span of about 9000 hours and should be replaced every year.
Frequently Asked Questions
How does a UV water sterilizer work?
It works by allowing water to enter the chamber of the UV housing. The water flows around a protective quartz sleeve, meaning it never makes direct contact with the actual UV lamp itself.
Are microorganisms killed instantly by UV light?
When hit by UV rays, the microorganisms' DNA becomes damaged, rendering them sterile and unable to replicate. While they may still be alive when leaving the housing, they cannot replicate and will eventually die off over time or be handled by your body's immune system.
Why is water pretreatment necessary for a UV system?
Proper pretreatment ensures that the incoming water is as clear as possible. Clear water allows the UV rays to penetrate fully, maximizing the disinfection effectiveness.
How do I choose the correct flow rate capacity for my UV sterilizer?
You should always purchase a UV sterilizer that is rated to handle a higher flow rate than your home’s peak water usage. This guarantees sufficient exposure time to safeguard your household water supply.
How long do UV lamps last and when should they be replaced?
UV lamps have a lifespan of approximately 9,000 hours of operation. To maintain complete protection, the lamp should be replaced once every year.
