Air Quality Measurement and Monitoring

[mark_m]

@Annie99

Now that COVID is finally recognised as being spread via airborne transmission and that improving ventilation is crucial to reducing risk (even if vaccinated), I’ve been thinking of getting a CO2 monitor

What’s the relationship between CO2 and Covid that you are relying on? It’s not something the medical experts have commented on.

Would greater circulation of air also be likely to increase the spread of airborn contaminants further?

Wearing a mask in public places has been the go to.
There is a separate Choice discussion on CO2 monitors. They are not readily available at low cost.

How to improve indoor air quality during this bushfire season

An interesting observation @SueW. The levels you observed of up to 1100ppm are not considered hazardous to health. Although twice that of fresh air urban environments typically also have elevated levels of CO2 due to motor vehicles, gas usage, etc A higher urban level of CO2 may be associated with greater motor vehicle exhaust or similar pollution. It’s not the CO2 that is the hazard. It’s the other stuff that may be produced along side it that is the hazard. A high CO2 level is not proof any …

Air Quality Measurement and Monitoring

An alternative might be to ask what is required to measure air quality in the family home? A simple answer is that it requires a range of specialised scientific instruments, and trained operators to collect samples. Typically the samples need to be taken away for remote analysis. There are no carry in the pocket instruments that are designed to measure air quality to recognised standards. There are a number of portable instruments that can measure specific gases or types of gases. Identifying…
