How to Limit the Spread of Infectious Disease in Buildings


Healthy buildings are part of the solution to lessening the spread of infectious diseases such as COVID-19

The spread of infectious diseases and viruses mean small particles can remain airborne for some period of time, and the rate of this transmission from human to human is also influenced by indoor conditions. This means the correct design and operation of your HVAC systems that move air can affect disease transmission in several ways, such as the following:


1. Supplying clean air to susceptible occupants 

2. Containing contaminated air and/or exhausting it to the outdoors 

3. Diluting the air in a space with cleaner air from outdoors and/0r by filtering the air

4. Cleaning the air within the room


What can you do? 

HVAC system’s air filters do eventually become clogged with pollutants. A clogged filter means the spread contaminants around your property and other parts of your HVAC system, continuing the circulation of contaminated air.

Check your filter by holding it up to the light. If the light can’t pass through it, it needs to be changed. You should be changing your air filter at least every three months to keep your heater and air conditioner working well.

What can we do? We’ve got the ability to deploy our own fully qualified engineers to service your HVAC system and limit what is known as ‘sick building syndrome’. We fully service and maintain all air conditioning systems paying special attention to cleaning or replacing clogged filters, and disinfecting coils as well as condensate trays in these units.

The cleaning solution we use kills 999% of bacterial and fungi in 60 seconds or less. This also improves energy efficiency and indoor air quality, and leave the units ultra-clean and smelling wonderful.

Indoor humidification systems can also combat the spread of disease by raising the temperature and humidity which lessens the survival time of viruses lingering in the air. Additionally, the respiratory tract’s defences are improved in people due to the more efficient cleaning of the airways and enhanced immune defences.

But, maintaining a clean air-handling unit will ultimately reduce what is introduced and spread into the air, whilst giving you peace of mind.
