Restroom cleanliness goes far beyond simply keeping everything neat and tidy. Even if it appears spotless, an odor emanating from a restroom will leave a customer with an unsatisfactory opinion of the business as a whole. While bathroom odors cannot be prevented, they may be easily managed. Air freshener dispensers are able to adequately deodorize restrooms without requiring much care. Dispensers may use gel or aerosol air fresheners and may include a fan to increase the range of the device. Many dispensers are metered so that several different factors can be controlled. The amount of freshener dispensed, the interval between dispensing and a start and stop time for the unit may be programmed to best suit each restroom’s specific needs. Air freshener dispensers run off batteries, making them convenient for any restroom.
