Humidifier Dyson AM10 - explanation of technology
Using Dyson’s patented Ultraviolet Cleanse technology, the Dyson humidifier neutralizes 99.9% of bacteria. Every drop of water is exposed to an ultraviolet light, twice, to neutralizes nasty bacteria. A piezoelectric transducer in the base of the machine, vibrating up to 1.7 million times a second, breaks the water down into microscopic particles, which are drawn up through the loop amplifier and projected through the air using Air Multiplier™ technology.

Living Biofilm - HABITANTES DEL MICROMUNDO
Many species of bacteria associate to create films that cover the wet or submerged surfaces. These films are called biofilms and in some cases they can be a serious problem for example, when appear on the surface of the surgical prosthesis or when blocking the drains of the houses. Nevertheless, in natural environments, such as the surface of trunks and stones submerged in ponds, lagoons and rivers, these biofilms act as great attractors to other organisms which find there a lot of food resources.
