Urinal Deodoriser for 30-day freshness. Releases optimised bacteria that clean the urinal and eliminates odours. The revolutionary design also reduces splash back while optimising the release of fragrance. Traps debris whilst still leaving the full view of the drain to ensure optimal flow. The P wave urinal screen shrinks in size as its fragrance and beneficial bacteria are released. The P Wave is safe for use in waterless urinals and can help reduce cleaning time by 50%.
