UV water filters what you need to know
Typically, water passes through several tests before it is supplied into our homes. The local municipalities employ different treatment methods to make water fit for use. However, there may be several accidents or leakages that add impurities into the water. For homeowners who use private wells, the risk of contamination in their water increase manifold. Most people use standard filtration systems like reverse osmosis systems, which offer a certain level of protection against impurities.The best filtration system to treat bacteria is the UV water filter.
People use ultraviolet lights for different purposes such as tanning or hygiene and infection control. It is no surprise then that UV lights are being used for water disinfection and purification. UV water filters eliminate microorganisms in water without using any chemicals and kill 99.9% of bacteria in the water. The bacteria are exposed to UV rays, rendering them inactive as they destroy their DNA, preventing them from growing and multiplying.
What are UV water filters?
A UV water filter refers to a purifier that eliminates harmful microbes in water through the use of germicidal ultraviolet light. The UV light in the filter destroys the nucleic acid in the DNA of the microbes rendering them unable to multiply and reproduce. The filters have unique lamps that emit UV light at a particular wavelength (254 nanometers). This wavelength creates radiation with more intensity than that produced by sunlight.
The success of a UV water filter depends on many factors, such as the intensity of radiation, exposure time, and water quality. This filtration system will not alter the taste, color, and odor of water if used alone.
What do UV systems eliminate?
Because there are no microorganisms resistant to UV light, the process eliminates most microbes such as cysts, algae, molds, viruses, and bacteria.
Why should you get a UV water filtration system?
UV treatment systems have many advantages over other treatment systems in the market. They include:
Other methods such as chlorination use harsh chemicals to treat water, change the chemistry, and impart a bad taste. UV systems do not use any chemicals and do not impact the chemistry or taste of the water in any way. If used in high concentrations, the chlorine will react with other chemicals in the water to produce toxic substances.
UV water filters are very cost-effective, and they only require an annual bulb change for maintenance.
UV treatment does not waste any water in the filtration process, unlike RO systems which remove a lot of water during the process.
UV systems are eco-friendly since no by-products are produced during the filtration process.
They are hassle-free since they don’t have any dirty or worn-out parts that need to be disposed of.
UV Treatment Vs. Boiling Water
Throughout history, people boiled water to kill microorganisms. However, this process has several limitations and does not remove all microbes.
Water needs to boil for at least 20 minutes to kill all microbes.
There is always the possibility of some microbes remaining even after boiling.
Water needs to cool down after boiling and before consumption. Reinfection may occur if left unattended.
The process of boiling water uses a lot of energy.
Boiling changes the taste of water.
