Why Replace Your UV Lamp Annually?

UV lamps lose approximately 20–30% of their germicidal output over the course of a year, even if they continue to glow. A lamp that looks operational may no longer be delivering sufficient UV intensity to inactivate bacteria, viruses, and other pathogens. Annual replacement is the standard recommendation from UV system manufacturers to ensure your water remains safe.
