What can an occupant do to reduce cooking emissions, regardless of whether or not they have a ducted range hood? We have over 150 families who have participated in the ROCIS Low Cost Monitoring Project (LCMP), and as such, had the opportunity to get immediate feedback on household particle counts as they cooked. Chime in with what worked, and what did not.
See the description of Alice La Pierre's emission reductions on the "Comment Wall".
Cook outside, as much as you can, and close your doors/windows while you do it ;)
