Ultraviolet Light Filters

Why UV Filters Matter

Over 11% of Irish households draw water from private sources like wells, springs, or lakes—and even public supply networks can occasionally require boil water alerts. Microbial contamination in water is typically seasonal, often linked to rainfall, and can stem from septic leakage, agricultural waste, or decaying organic matter.

Using UV disinfection offers a chemical free, eco conscious method to eliminate harmful bacteria, viruses, molds, and spores. Unlike chlorine systems, UV doesn’t affect your water’s taste or smell. It’s a go to solution in food and drink industries across Ireland due to stringent health regulations.
