FAQs
Are whole house water purifiers worth it?
Yes, UV water purifiers are very effective at removing 99.99% of microbiological contaminants including bacteria, fungi, protozoans, viruses, and cysts.
Does UV light really sanitize water?
Yes, ultraviolet light (UV) is a proven method for sanitizing water. When water passes through a UV disinfection system, the UV light disrupts the DNA or RNA of microorganisms, such as bacteria, viruses, and protozoa. This prevents them from reproducing and effectively renders them harmless. UV disinfection is considered environmentally friendly as it does not require harsh chemicals. However, it's crucial to maintain the UV system properly, ensuring the light intensity is sufficient and the water is clear of any turbidity or sediment that might shield microorganisms from the UV rays.
