Urinal screens offer another effective means of odor control. Fragrances are released during use so patrons smell a pleasant scent rather than urine. In addition, many screens fight odors by releasing enzymes. Enzymes help dissolve organic compounds and uric salt in P-traps and lines, which are often the root causes of restroom odor problems.

Urinal screens are disposable and can be discarded after the urinal block in the screen breaks down or dissolves. Since they shrink over their lifetime they provide a visual alert as to when they must be replaced. Typically screens should be changed every 30 days to remain effective.
