Create a mini eco-system at the comfort of your own bathroom using Jun Yasumoto’s Phyto-Purification, a natural filtering principle for your bathroom. Every time a household member uses the bathroom, the use water from the shower and the washbasin will be filtered first to the organic system before being recycled. Jun’s Phyto-purification is a natural way of recycling water, and is commonly used in ecological purification systems. This creation is great in keeping your bathroom green. However, I am not sure if this prevents those wildlife creatures to live in your bathroom as well. However, the idea itself is great.
