How to choose an UV water filter for your home?

Standard home water filtration systems may offer a certain level of protection against bacteria, however, water known to be more problematic from a microbiological standpoint is best treated with the help of an UV water filter. UV water filters are capable of eradicating 99.9% of bacteria in water, thus removing a wide range of water-borne pathogens, bacteria that cause gastrointestinal problems, viruses, and other harmful microorganisms. Exposure to UV lights renders microorganisms inactive by destroying their DNA, and preventing them from infecting or multiplying. All this is achieved without changing or influencing the taste of water in any way.

Ultraviolet pre-filtration systems – a must-have for UV water filters

Ultraviolet water filters work in a straightforward way – water gets purified by being exposed to UV lights, which are capable of inactivating even microorganisms that have a high tolerance to chlorine or other chemical disinfectants.

Why do I need a pre-filter with an UV water filter?

UV water filters are best at destroying bacteria, viruses and other microorganisms in water. Unlike other types of filters that remove contaminants by trapping them in their filter media, UV water filters use UV lights to inactivate or neutralise bacteria, rendering them unable to infect again or even to reproduce. But this is not the actual reason why you need a pre-filter with an UV water filter.

Advantages and disadvantages of UV water filters

UV water filters are predominantly used as an alternative to chlorination, even in large-scale settings like wastewater treatment. In several cities, UV wastewater treatment is commonly replacing chlorination. Thanks to its ability to disinfect water without the use of any chemicals, ultraviolet water filtration is a much healthier option, and it’s even capable of being effective against chlorine-resistant bacteria. However, like most water filtration systems, UV water filtration is not capable of addressing problems caused by other types of contaminants like inorganic compounds, particles, or dissolved organics, which is why a pre-filter is an absolute must with UV water filters. Most of this water treatment method’s shortcomings are due to it being specialised solely on microbiological issues.
