Eco-friendly literally means earth-friendly or not harmful to the environment. Our eco-friendly Alpine Screen urinal screens use no chemicals and are VOC compliant with no ozone depleting ingredients. Also, Alpine Screens contain no para dichlorobenzene, a potential carcinogen often found in other urinal screens and toilet blocks. For a limited time, we are offering free Alpine-Screen samples for our customers in Green Bay, Milwaukee, Madison, Wausau and throughout Wisconsin, Northern Illinois and the UP.
