Scented enzyme urinal screens attack the problem of smell in your washroom from two completely different angles. As soon as the mat is placed in a clean urinal the premium fragrances work to mask any residual odour which may be present. The 50g enzymatic bacterial block at its centre then releases beneficial bacteria which digest the odour causing anaerobic bacteria, resulting in long term removal of malodours. The 50g block has a concentration of beneficial enzyme based bacteria to the level of 5.9 x 10 to the eighth per gram ensuring rapid response to lingering odours for up to 30 days. The screen will reduce the urine splash by up to 95% reducing cleaning time.
