Performance of the Airy system

As a rule of thumb, we recommend one system with one plant per room. One Airy model M system can purify a room with a size of up to 20 square meters within a 24 hours timeframe. For instance, a larger room of up to 60 square meters would require three Airy model M systems with three plants. There is simply no other cheaper and easier way to purify indoor air (other than perhaps opening the window at least three times per day if possible). Our research, tests and testimonials demonstrate the efficiency of the Airy bio-filtration system. On the other hand, the academic scientific research recognises that potted plants (plants used in a traditional pot) have a very limited impact on improving indoor air quality, but suggests that “Future experiments should instead investigate VOC uptake mechanisms and alternative bio-filtration technologies”. That is why Airy is moving ahead and has already demonstrated on its own about the benefits of its proprietary bio-filtration system, as per some of the following scientific research ordered by Airy:

  • The Fraunhofer WKI (in 2018, test report No. MAIC-2018-4946 and No. MAIC-2018-4944) demonstrated that the Airy system reduced the concentration of formaldehyde by almost 50%, the concentration of toluene by almost 30% and the concentration of xylene by almost 20%. In this test, a Dracaena plant was used, in a controlled-chamber;
  • The Helmholtz Zentrum München (fka “GSF-Forschungszentrum“) (in 1994) demonstrated the effectiveness of the plant to convert indoor air pollutants (formaldehyde in this case) into non-toxic nutrients such as glucose and amino acids;
  • Beijing Peking University (in 2005) tested the purifying attributes of plants with two specially designed controlled-chambers: researchers fitted one chamber with a plant inside an Airy M system (fka “polluSan”), and the other chamber remained empty. Then, they added identical amounts of pollutants to each chamber, and measured the concentration levels 24 hours later. Results showed that the two plants they used (cornstalk and spathiphyllum) removed up to 77% of the benzene and up to 80% of the formaldehyde;
  • Kirchner GmbH, an engineering company for environmental protection based in Hamburg, conducted a study in 2005 measuring the effectiveness of Airy to filter formaldehyde in a room of 37 square meters with furniture. It showed that Airy was effective at reducing the formaldehyde concentration by up to 50%;
  •  In January 2020, M.TEC Engineering conducted a study measuring the effectiveness of Airy System L on relative humidity level in a room of 30 square meters with furniture and people. It showed that utilizing Airy System L in a dry room can increase the relative humidity level by up to 10% rH during the first 24 hours.
