Why is harm from air pollutants still so prevalent? There are several reasons.

While we manage IAQ to decrease exposure to airborne pathogens, such as SARS-CoV-2, we need to be extremely careful to avoid IAQ management that has the unintended consequence of suppressing our immune system, making us more vulnerable to infections, inflammatory diseases, and cancer. 

At the present time, many people are unaware of the health significance of indoor contaminants that they cannot smell or feel through irritation of their respiratory tract.

When people became aware that transmission of SARS-CoV-2 was primarily through the air, reducing airborne exposure in buildings immediately became a high priority. 

As parents who want the best for our kids, we go to great lengths to make sure their living and playing spaces are safe from physical dangers.

In the past several years, there has been much discussion on the influence of indoor environments on the spread of diseases caused by viruses and bacteria.

Volatile organic compounds (VOCs) are airborne carbon-based molecules produced by chemicals vaporizing at room temperature.

The adage that increasing outdoor air ventilation will improve IAQ is not always the case. For example, how do you manage ventilation to support occupant health if outdoor air is polluted by an upwind wildfire or an accident that spilled airborne toxins?

Are there lessons from Fibonacci ratios that could be used by engineers to improve fans blades for air movement, size HVAC ducts, or design economical mechanical systems?

Exposures in homes with intermittent peaks of NO2 have been associated with numerous concerns, including severe asthma in children and adults.
