Scent - Tropical Sealed bristle technology prevents splashback and spread of disease-causing microbes caused by urine impacting the back wall or still water in a public urinal. With the reduction of splashback and our anti-microbial technology, a cleaner public restroom is achieved through eliminating the odour at the source rather than just masking a smell. The ëkco Urinal Screen lasts twice as long as other screens on the market and is perfect for waterless urinals
