Three steps to take now to improve Indoor Air Quality in the Age of Coronavirus.

(Updated chart 11/23/20) Whether your building is open, opening soon or closed until next year, you are behind if you’re not already planning to improve indoor air quality (IAQ) at your facility. (See “Why Good IAQ Matters in the Age of COVID-19.”) If you made changes to improve safety back in May or June (as we transitioned out of total lockdown), new information, products and tools that we discuss here may mean you’re looking at making changes again.

I would love to be 100% on board with this recommendation all year round. But I’m not.

Some estimates place the cost of poor indoor air quality (IAQ) to the United States' economy at $200 Billion in today’s dollars. In the age of COVID-19, good IAQ as we have known it is no longer enough. (Updated chart, 11/23/20)
