Beijing University confirms the effectiveness of the predecessor model polluSan
In 2005 Beijing University tested the purifying attributes of plants with two specially designed chambers. The researchers fitted one chamber with a plant inside a polluSan pot, the other remained empty. The researchers than added identical amounts of pollutants to each chamber, and 24 hours later measured the concentration of pollutants.
The test result showed that the two plants, the cornstalk plant and spathe flower demonstrated strong results. They removed 77% of the benzol and over 80% of the formaldehyde concentration. Within 24 hours the plants removed a significant proportion of the pollutants from the chamber.
Do you have additional scientific proof?
Yes! Before the introduction of AIRY, its predecessor “polluSan” was the subject of various scientific studies, amongst others by TÜV, the Beijng University, the Environmental Protection Encouragement Agency (EPEA) as well as two additional surveys. polluSan was significantly improved on an launche das AIY in 2016.
Study by Kircher GmbH
Kirchner GmbH, an engineering company for environmental protection took a different approach to measuring the effectiveness of polluSan. They measured the formaldehyde concentration in a room of 37 m2 including furniture before and after placing a plant in a polluSan pot in the room. The result was, that the formaldehyde concentration was reduced by 50%.
Another study from 2005 demonstrated the the range of pollutants, that plants can reduce. IN this study the complete house was fitted with an IDS plant systems. (It was suspected that the house had a high concentration of pollutants, because the resident had shown symptoms of the sick building syndrome)
Comparable measurements showed a significant reduction especially for plasticiser and pyrethroid. Please refer to the study by Kirchner GmbH.
