Summer's here and wildfires are looming large - now is the time to prep for woodsmoke events. I'm sharing some of my thoughts on creating a "clean room" in your home using air cleaning, air sealing, and simple strategies for managing indoor emissions:

One more study presented by Brett Stinson comparing PM removal from simulated wildfire smoke. CR box wins again.

Fantastic work by Amity and @brettwstinson. Check out the open access paper here: sciencedirect.com/science/ar…

Amity Deters of Portland State University presented conclusions of outstanding research on CR Boxes. Once again, CR Boxes work very well with effectiveness (reductions in wildfire smoke particles) of approximately 90% or higher in model spaces.

Fantastic cover for the great work, by lead author @brettwstinson
In this ACS ES&T Air article, @etgall of @Portland_State characterizes and evaluates the ability of #aircleaners to remove particle and gas-phase pollutants under realistic indoor #wildfiresmoke conditions.

The CDC has stated "construction quality...could substantially affect the performance of DIY air filtration units". Our new study on CR Boxes sought to investigate this claim. Main result? 8 novices built 8 different CR Boxes w/ 8% variability in CADR.

Finally, we modeled a scenario where a newly-built CR box is immediately deployed, e.g. to a bedroom during a wildfire smoke event. Across AER 0.1-1 /h, CR box significantly reduces PM2.5 while there was a short period of elevated BTEX due to off-gassing from tape.

This was a really fun study, with great work by @brettwstinson and enabled by a fantastic summer undergrad Amity Deters, who will be presenting this work @IndoorAir2024!

Glad to share our recently published study in ES&T Air evaluating 13 different air cleaners for PM and VOC removal under wildfire smoke conditions. We evaluated 13 different commercial and DIY air cleaners in a test chamber w/ pine needle wildfire smoke challenge

Some quick findings. All tests on highest setting. DIY builds (CR Box (D1), local design called Owl air (D2)) had high PM CADRs, variable across particle size. H = HEPA filter, S = sorbent, A = additive, D = Do-it-yourself. Not naming commercial units, so please don't ask.

So our survey of commercial and DIY units points to some trade-offs if one is looking for removal of both gas- and particle-phase pollutants in wildfire smoke. Great work by Brett Stinson and @LaguerreAurelie on this. More to come soon!
