Another study designed to push an agenda. How tiny?
Watch, they’ll have had the stove running for hours, with no range hood, and all the windows sealed to prevent any air exchange with the outside.
Other indoor air pollution studies have used those kinds of deceit to get the desired results.
When you fry anything, grease splatters all over the place. It doesn’t matter whether the stove is gas or electric. The smoke from the burning food has umpteen gazillion times as many nanoparticles as the combustion gasses from the gas flame.
AND the “tiny home” will be designed to modern efficiency standards of 0.1 Air Changes per Hour (ACH). Follow modern design requirements and get your nanoparticles.
