Scientists at NASA’s Stennis Space Center originally developed the concept of placing a plant in a mixture of soil and activated carbon and mechanically moving air down to the plant’s roots. A working model equalled the VOC removal capacity of fifteen regularly grown interior plants.
In 1990 Dr. Wolverton set about to further develop this bio-
WES later licensed the technology to Actree Corporation, a Japanese engineering and manufacturing company. Jointly, the two companies made further refinements to the filter. Actree produced and marketed in Japan a small portable air filter termed the EcoPlanter. The EcoPlanter employed a quiet two-
Thus, we later connected with U.S. Health Equipment Company to produce the Plant Air Purifier® here in the U.S. Most conventional air filtration devices in the market today use activated carbon and/or high-
The Plant Air Purifier® system pulls air down through the growth media where the air pollutants are captured by activated carbon. The activated carbon and pebbles have porous surfaces that hold the pollutants in place, allowing microbes in the root zone to break them down into components that both the plant and themselves can digest. Thus, the Plant Air Purifier is bioregenerative (self-
