Rain Maker Water Purifier is an innovative human-powered water filtration system designed to provide clean drinking water in areas without reliable electricity access. This groundbreaking design, created by Yong Sang Kang and awarded the prestigious Silver A' Design Award in the Home Appliances Design category, employs a sophisticated membrane filtration system capable of removing 99% of bacteria and germs from non-potable water sources, including surface water, underground water, and rainwater. The device's ingenious design features two cone shapes positioned base-to-base, creating an efficient filtration chamber that operates through human weight pressure, generating approximately 1kgf/cm² (14psi) necessary for optimal filtration. Standing at 360mm in height with a 200mm diameter, the purifier incorporates a unique back-flushing mechanism that significantly extends the filter's lifespan compared to conventional purifiers. The system utilizes advanced membrane technology with pores under 0.4 microns, ensuring effective removal of harmful microorganisms. Its intuitive operation involves a simple process of collecting settled water, applying pressure through body weight, and utilizing the innovative back-flushing feature for maintenance. The design incorporates BioCleanAct™ Anti-microbial technology and employs safe, non-toxic materials that comply with international safety standards. This humanitarian-focused innovation particularly addresses the critical need for clean water access in underdeveloped regions and disaster-struck areas, offering a sustainable solution that operates independently of electrical infrastructure while maintaining high purification standards.
