In order to achieve pore cleaning and long-lasting makeup, some products contain microbeads. The size of microbeads in general products is between 0.2mm to 2mm. The sewage treatment plant is not able to filter out microbeads effectively, so microbeads are discharged into the sea and absorb toxic substances. Last, through the food chain, these toxic microbeads will not only cause the destruction of marine ecology, but also do harm to our health. This product is a set of household water purification system, which is installed under the sink. The product uses the principle that the boiling point of water is lower than plastic. The system first heats the sewage, separating water from the microbeads by evaporation. Then, it cools down the vapor to clean water, and leaves the microbeads. This way we can recycle, reuse the plastic material and protect the environment.
