UV light technology, a chemical-free way
to address microorganisms.
The Hudson River Valley is just a quick car ride away from Glasco UV’s manufacturing facility in Mahwah, NJ. While the countryside draws you in, it’s the waterway that inspires us.

Our company has been delivering
state-of-the-art UV technology for decades.
There’s so much about Glasco UV to discover. We’re a woman-owned company that manufactures American-made UV systems, replacements and retrofits for water and wastewater treatment in residential, commercial, industrial and municipal applications. We’ve completed more than 1,500 installations worldwide and we’re not slowing down.
