AAVI Leaf® air purifiers are also suitable for hospital use
AAVI® technology is proven to remove microbes from indoor air, and AAVI® air purifiers are thus an excellent method in the fight against the spread of microbes, viruses and bacteria in hospital environments.
Disease-causing microbes are very small in size. Typically, flu-causing viruses are sized from 80 to 120 nm, but bacteria or clusters can be much larger, up to several micrometers. Particles of the size of viruses travel in the air for long periods of time (hours) and distances. However, bacteria also remain in air currents, settling on the surfaces relatively quickly, mostly within tens of minutes.
The most significant transmission of microbes that are causing respiratory diseases occurs through the air via aerosols and droplets, and indirectly through surfaces. Breathing, talking, sneezing and coughing are the most significant sources of respiratory pathogens. Up to 40,000 droplets fly at a maximum speed of 100 m / s, and a cough can produce 3,000 droplet cores, as seen in Figure 1. Large droplets fall quickly on the floor or other surfaces, but medium-sized (5 µm… 100 µm) droplets can travel in the air for some distance and then transmit to people nearby. These droplets can also form smaller aerosols as the water evaporates. These droplet cores and small aerosols (<5 µm) linger in the air for long periods of time. They travel with air currents and are spread everywhere by turbulence vortices.
