What level of air pollution exposure do you have? Have you monitored your indoor air quality with a PM2.5 device, or used an air purifier? Do you live near a busy road, or a coal plant?

Good luck for your treatment and recovery.

I live in Denver. I have not done any testing but moved into this house June 2019. Our inspection found the radon levels to be 3.9 pCi/L (4.0 is the recommended actionable cut-off). I recently installed a radon abatement system as we're refinishing the basement. Wish I knew for sure.
