Health Gards® Metered Aerosols, featuring “Neutrex®” the Smart Odor Neutralizer, are specially formulated for public restrooms and other large rooms. Covers up to 6,000 cubic feet. Universal spray actuator fits most competitive dispensers. The 7 oz. can provides 30 days of continuous deodorization, when the dispenser is set for 24-hour function at 15-minute intervals. By adjusting operational settings to day or night, you will extend the life of the can. Decreasing the intervals between sprays will deplete the can faster; increasing the spray intervals will extend the can’s life.
