Pros & Cons of UV Water Filtration

Ultraviolet water purification is the most effective method for disinfecting bacteria from the water. Ultraviolet (UV) rays penetrate harmful pathogens in your home’s water and destroy illness-causing microorganisms by attacking their genetic core (DNA). This is extremely efficient in eliminating their ability to reproduce. Disinfecting your water with Ultraviolet light is exceptionably simple, effective and environmentally safe. UV systems destroy 99.99% of harmful microorganisms without adding chemicals or changing your water’s taste or odor. UV water purification is usually used with other forms of filtration such as reverse osmosis systems or carbon block filters.

UV Purification > Chemical Disinfectant
UV systems are an effective means of water disinfection for residential point of entry use to help disinfect the entire home. UV systems are highly recommended to homeowners who may suspect any E.coli, cryptosporidium, giardia or any other types of bacteria and viruses in the water. It is not advised to use chlorine or other chemicals to disinfect water like private well owners, because of the toxic byproducts they create. It is important to avoid drinking any water that is potentially contaminated from bacteria to protect yourself from any water-borne bacterial diseases.

Ultraviolet Purification Advantages

  • Chemical Free: UV purification does not use any chemicals like chlorine or leave any harmful by products.
  • Taste & Odor Free: UV does not add any chemical taste or odor to the water.
  • Extremely Effective: One of the most effective ways to kill disease-causing microbes by destroying 99.99%.
  • Requires very little energy: Uses about the same energy as it would to run a 60 watt light bulb.
  • Low Maintenance: Set and forget type of system, just change UV bulb annually.

Limitations in UV Water Systems
Ultraviolet purification itself is not enough to purify water down to drinking water purposes. This is because the UV radiation is only effective for treating bacteria and viruses. UV light does not work to eliminate contaminants such as chlorine, heavy metals and VOC’s (Volatile Organic Compounds). UV systems are often paired with Reverse Osmosis Systems to provide a complete purification process for the safest drinking water.

Choosing the Right UV Unit Size
If you draw water from a private water supply it is recommended to treat your entire home. To assure the highest satisfaction, choose the right size (gpm) of UV system that matches your household peak demand flow rate. This is simply a measure of how much water can flow through your main water line if all the water outlets were opened at once.
