Air Purifier vs. Positive Pressure Fresh Air System – An Unfair Battle?
Author of the article, happy to answer any questions.<p>A bit of background, my house is in Northern Thailand that has similar levels of air pollution every year than what we see currently in North America and Canada and it took me a few years to get my house to zero PM even when having the worst wildfires around. So before installing a positive pressure system and making my house air tight in the process, I experienced with all types of air purifiers but did not find anything that works consistently at very high pollution levels.<p>The experience with these wildfires let me actually found AirGradient and we are proud of open sourcing many of our air quality monitors.
