Ok, here' s a weird one.
I've learned how to make great pan-seared steaks in my city apartment, with a kitchen lacking ventilation. High heat is the key, of course. (along with airing out the steak). This beats most steak dinners I've had in Argentina's "top rated" (tourist) steak houses and beats NYC steak houses, because the attitude doesn't come with the meal. ;)
I tape off my kitchen with plastic wrap. I wear a P100 ventillator. And I sear the steak for 1-2 minutes. It makes crazy smoke. I installed a range hood with a smoke filter, but that does a very paltry job, as you could imagine.
I am considering running another home made filter system, consisting of a box fan with an air filter taped across the front.
I've done this before, which works for general air quality, but never for smoke removal.
I know it won't be perfect, but it will help. Researching box fans, vornado fans, even commercial blowers.
Any other ideas?
