Humidity coming from bathroom, and lower the quality of linen is one of our concern. In order to prevent this situation, we already have introduce several equipments. A ventilation fan will be installed in the bathroom and low temperature air-conditioner so as to keep a desiccated area. Besides, dehumidified bag will be placed in every storey of rack which helps absorb the moisture. Also, when designing the bathroom in staff lounge, we install two doors, one is in the bathroom and another one is in the staff lounge entrance. All of these can help maintain the humidity in the floor pantry and keep the quality of linen effectively
