Scientists confirm the air purifying qualities of AIRY

The effectivenessof AIRY was scientifically proven multiple times, most recently by Frauenhofer Institute. When compared to a plant in a traditional flower pot, the AIRY system was multiple times more effective. A plant in a AIRY pot system is significantly more effective than one in a traditional flower pot, as stated by the Fraunhofer Institute.

The concentration of Toluol was reduced by 30%, that of Xylol by 17%, while a plant in a traditional pot showed no measurable reduction of these two pollutants.

The effectiveness of removing Formaldehyde was also proven by the Fraunhofer Institute. The researchers also demonstrated, that an AIRY pot filled with nothing but soil already removes pollutants from the air, solely by creating a constant air flow through the soil.

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.

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.

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.
