Yes, UV water filters can be effective at removing bacteria and other microorganisms from water. UV water filters use a process called ultraviolet disinfection, which involves passing water through a chamber containing a UV light.
The UV light is able to kill bacteria and other microorganisms in the water, making it safe to drink. UV water filters are typically used as a final step in the water treatment process, after the water has been filtered to remove any physical contaminants.
This type of water filter is effective at removing bacteria and other microorganisms, but it is not able to remove chemical contaminants from water.
People ask this question because of the fear of getting the opposite results after purchasing a UV water filter. However, you shouldn’t have to worry because the UV water filters work.
These filters use ultraviolet rays to eliminate all the viruses, bacteria, protozoa, fungi, and more. The ultraviolet rays’ maximum concentration destroys the DNA of these microorganisms by penetrating through their cell wall and scramble the nucleic acid of their DNA hence preventing them from reproducing, making the water safe and clean for drinking.
However, it’s important to note that some bacteria and protozoa such as Cryptosporidium and Giardia, have a thick cell wall that any amount of UV may not destroy them; therefore, it’s best to use the highest amount of ultraviolet rays to ensure 99.99% destruction of the bacteria in the water; and also to ensure that the specific UV light sterilization system is designed for such bacteria and viruses for you to observe effective results.
Also, you should note that the UV water filter only destroys the bacteria and leaves them suspended in the water and also does not eliminate chemical contaminants.
Therefore, it’s best to go for a UV filter that uses reverse osmosis to eliminate the bacteria and filter out their dead bodies floating on water to achieve an effective water filtration process.
If not, you can add pre-filtration systems such as sediment filters and carbon filters that filter out water and make it clear before it undergoes a disinfection process that effectively destroys all the bacteria present in the water hence making it safe and clean for drinking.
