UV Water Purification Disadvantages

UV water purifiers are not suitable for treating dirty or muddy water.

When water contains large amounts of sediment particles, these particles block UV light from reaching microorganisms. Install a pre-filter to treat turbid water before treating the water with a UV water filter. Only then can viruses and bacteria be treated in a UV water filter. So that's why UV is usually placed in the last step of water treatment.

UV water sterilisers cannot remove pesticides and other chemicals

UV water purifier systems can undoubtedly kill bacteria, viruses and germs that contaminate your water, but if your water contains harmful chemicals, heavy metals, etc., the dissolved salts and impurities in the water will remain intact even after treatment with a UV filter. That's because UV light is only effective in treating living organisms.

UV does not physically remove microorganisms

Outer rays penetrate the cells of pathogens and disrupt their DNA, thus preventing them from reproducing. But their bodies are not completely eliminated from the water. The carcasses remain in the water, making it unfit for drinking.

Most people feel more comfortable with reverse osmosis filtration methods.

UV water purification relies on electricity

UV lamps need to be powered by an electrical source, and although UV filters are cheaper to operate, if the power goes out and the water previously in the bottle has been used up, then you have no more filtered water to drink.

Most UV water filters on the market do not have a storage tank.

UV filtration systems do not have a tank to store the water that has been treated with UV radiation. This means that when you turn on the tap, the drinking water needs to flow through the UV system before it can leave the tap.

Another problem is that a small amount of water remains in the UV chamber when the water is not being used. This water is heated by the UV light, so when you turn on the tap, a small amount of warm water is the first thing to come out.

It's hard to know when to replace the lamp

UV water purifiers work on the principle of ultraviolet light. Since UV light is invisible, it is impossible to see how this purifier system works with the naked eye. It is impossible for the user to know when it is time to change the light, and as a result, you may end up drinking impure and untreated water. All you can do is follow the manufacturer's guidelines and replace the lamp as recommended in the user manual.
