1. Compared to standard ultrasonic technology (non warm mist), Philips NanoCloud technology emits up to 99% less natural bacteria into the air, as tested for 8 weeks in a 1m3 chamber, and certified in an independent laboratory benchmark study by Rabe HygieneConsult in June 2012 (Rabe Hygiene Consult 2101p_12.116).
2. Independent third-party test Determination of deposition of minerals from liquid droplets on furniture according to DIN 44973, IUTA e.V. (Institut für Energie- und Umwelttechnik) (139/08 – 55955.00), December 2008, to determine mineral deposits onto furniture from airborne liquid droplets over a period of 3 hours. NanoCloud demonstrated negligible deposition of minerals, whereas ultrasonic devices produced depositions of droplets of salt solution near the devices.
