Airborne Infection Control

Medixair provides effective airborne infection control to help minimise infection spread in several indoor environments. The UV air steriliser works by targeting airborne microorganisms and eliminating them from the environment to reduce aerosol transmission.

How Infections Are Transmitted

There are four main methods in which infections are transmitted, they are:

FOOD
Food infection control

Controlled by:

  • Food hygiene practices
CONTACT
Contact infection control

Controlled by:

  • Hand washing
  • PPE
OBJECTS
Objects infection control

Controlled by:

  • Cleaning
AIRBORNE

The Problem

AIRBORNE TRANSMISSION

How to prevent airborne transmission

Preventing airborne transmission of diseases and controlling infection spread can be achieved with the right UV air steriliser and purifier. Airborne transmission occurs by dissemination of either airborne droplet nuclei, from partly evaporated droplets containing pathogenic micro-organisms, or by very small droplets known as aerosols also containing the infectious agent. These aerosols cannot be seen and are suspended in the air for long periods of time, dispersed by air currents. Medixair UV Air Purifier utilises UV light to kill the aerosols within the air, ensuring that they are unable to spread from host to host.

DROPLET TRANSMISSION

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.

Airborne aerosols

AEROSOLS

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.

Microorganisms can spread in a number of ways, for example, through food handling when correct hygiene procedures are not followed, through touch-to-touch contact, or by touching the same objects. In addition, microorganisms can spread through the air when someone coughs. By implementing effective airborne infection control, it is possible to control infections and ensure that microorganisms are being eliminated when airborne, therefore making them unable to move from person to person and effective in controlling infections.

COVERAGE

Medixair coverage
  • 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.
