No, a UV water purifier does not soften hard water. UV water purifiers, like the ones offered by Infinity Sales & Services, are designed to kill harmful microorganisms like bacteria and viruses. The purifiers use Ultra Violet (UV) light to purify the water by exposing it to UV light. This process kills the harmful microorganisms and makes the water safe for consumption. However, a UV water purifier does not have the ability to soften hard water. Hard water contains high levels of minerals like calcium and magnesium, which can cause problems like clogging of pipes, reduced efficiency of appliances, and dry skin. To resolve the issue of hard water, a water softener is required.
