The last point in the Engineering column is so very important. Often air handling systems are the most neglected.
Out of sight - Out of mind.
Bringing fresh air into a large ducted system is not easy. #HVAC systems are designed to bring in only 20% fresh air this means 80% is re-circulated. Yes you are breathing the exhaled air of the person that you don't like down the hall.
If a building has wall hung split systems or ceiling cassettes, then introduction of fresh air can only be through opening a window as these units only heat or cool the air in the room. Have a look at our post "Does Coronavirus spread through air conditioning? This was posted here on July 8th.
#Sanitising and cleaning air handling systems is often very low on the list of priorities of building managers and owners. They are out of sight !
Just look up at the air conditioning supply registers (air blowing into the room), see if there are black streaks of dust on the ceiling.
If the answer is yes - the system is filthy inside and is a vector for spreading many harmful #pathogens throughout your building.
End to end #sanitizing of your #airconditioning system is easier than you might think.
No matter where you are ask me how....
