Urinal screens are small, often disposable mats placed inside urinals to help prevent clogs and control odors. They are typically made from plastic or rubber and come in various shapes and colors. The screens often contain fragrances that help mask unpleasant smells and can also have antimicrobial properties to reduce bacteria. These screens are commonly used in public restrooms, such as those found in restaurants, offices, and schools. By trapping debris and preventing it from entering the plumbing, urinal screens can help maintain cleanliness and reduce maintenance costs for facilities.
