How Infections Are Transmitted
There are four main methods in which infections are transmitted, they are:
- Food hygiene practices
- Hand washing
Large droplets will only be propelled a short distances (2m) through the air, They will however then settle on surfaces and can become airborne again from natural air currents created from activity in the room. Furthermore evaporation of the droplet will make them smaller called droplet nuclei, placing them in a state where they can re-infect a susceptible host.
Also released by coughing and sneezing there are much smaller droplets which are light enough to float. They can move over longer distances and stay airborne for longer periods. These droplets will be widely dispersed by air currents before being inhaled, or deposited on surfaces, equipment etc.
Ventilate the room
Turn down heating
Modify air conditioning to increase to percentage of fresh air
Investigate with maintenance teams
Still a problem?
If you have rooms that are small, kept above average temperature and heavily used?
A UV air steriliser1 is a plug and play solution

Summary of disinfection technologies for microbial control.
Germicidal UV (GUV) is a technology that could be beneficial for decontamination and reducing aerosol concentrations in some occupied environments.
HOW MEDIXAIR WILL EFFECTIVELY CONTROL AIRBORNE TRANSMISSION
Air drawn through medixair’s chamber at a controlled speed
Airborne pathogens are exposed to high levels of UVc radiation
Controlled air speed +
Powerful UVc exposure =
- Covers 25m2 area
- Whisper quiet
- No ozone produced
- 90W power consumption
- Wall mount or mobile stand options available
A single Medixair unit will emit 25m3 of sterilised air per hour
Medixair can provide differing levels of protection against aerobiological contamination, providing an air changes every hour, or every two or three hours as required.
The level of protection provided may be adjusted by varying the number of units installed in any given space.
Unless there is a reason to do otherwise (i.e. an extreme level of risk) we recommend one machine to treat 75m3.
Therefore, with a typical room height of approximately 2.5 m this would equate to a floor area of 30m2. (75m3/2.5m).
For example, a 6m x 5m room.
|Suggested Air Change Time Periods|
|Clinical treatment Room||1hr|
|Hospital Side Room||1hr|
|Kitchen or Laundry||3hrs|
