UV Disinfection Units

For Pennsylvania or New Jersey residents, ultraviolet (UV) sterilizers are an effective solution for treating bacteria in well water systems. These sterilizers utilize a 254-nanometer UV wavelength to target and eliminate harmful bacteria. Available in various flow rates, these units are designed to match your specific water needs.

It is important to change the bulbs on an annual basis for optimal performance. When selecting a UV sterilizer, units made of stainless steel are recommended for durability. Additionally, while optional, it is advisable to consider incorporating pre-filters and alarms for enhanced system performance and peace of mind.

Does UV Kill Bacteria?

Yes, ultraviolet (UV) disinfection units are effective at killing bacteria. UV disinfection works by exposing water to ultraviolet light, typically at a wavelength of 254 nanometers. This wavelength is specifically designed to target the genetic material of bacteria, viruses, and other microorganisms, disrupting their DNA and rendering them unable to reproduce or cause infection. When water passes through a UV disinfection unit, any bacteria present in the water is then exposed to the UV light, which damages their genetic material and effectively neutralizes them.

It’s important to note that UV disinfection primarily targets bacteria and viruses but may not be as effective against other contaminants such as chemicals, heavy metals, and sediment. Additional water treatment methods or filtration systems may be necessary to address these specific contaminants, depending on the water quality and your specific needs, which our professional water experts can recommend.

Best of all, UV disinfection is a chemical-free and environmentally friendly method for treating water, as it does not require the use of chemicals or produce harmful byproducts.

How Effective is UV Water Treatment?

UV water treatment is highly effective at neutralizing a wide range of microorganisms, including bacteria, viruses, and protozoa. When properly installed and maintained, UV water treatment systems can achieve a high level of disinfection, providing safe and clean drinking water.

Depending on the system and the quality of the water, UV treatment can typically achieve a 4-log (99.99%) or higher reduction of bacteria and viruses. This level of disinfection is considered highly effective in providing safe drinking water.


UV water filters provide a chemical-free water treatment solution. This process doesn’t add anything to your water, it only physically attacks the structure of bacteria within your water. UV water filters don’t contain any chemically-active elements, nor use heat for treatment.
