An air purifier is pretty cheap and will cut down on indoor pollution from cooking a lot. Or at least that’s how it seemed from the somewhat unreliable sensor I was using.
FWIW, I think the wirecutter's quality for air purifiers is pretty bad, and likely more influenced by affiliate payments than science: https://dynomight.net/ikea-purifier/
I tried the cheap IKEA model and with my severe dust mite allergies the model was insufficient in comparison to calm my sixth sinus-bound sense.
My main suspicion: In my last 3 abodes with pre-1955 construction in East Coast, the pre-filter on the top Wirecutter pick needs to be cleaned 3x per carbon filter replacement in order to reduce largest particle accumulation on the carbon or HEPA filters.
The inexpensive IKEA model did not have a viable and easily cleaned pre filter as far as I could figure out.
The ikea Fornuftig has a snap-on piece of cloth covered plastic that serves as a pre-filter, a replaceable particle filter, and a replaceable optional gas filter.
I've found that taking a shop vac and leaf blower to the pre-filter works quite well to get it clean.
That said, the Ikea air purifiers only make sense if you have a room that's about the right size for the Fornuftig. Their larger purifier is worse value, and you're better off looking at something like the Squair.
I am homeless, I live in a minivan, and I have a solar battery charger with a small carbon filter/HEPA air filter that I use every night and it helps me so much. I am a very "sensitive" person to many things in the environment, but many times while traveling i find myself in the midst of wildfire smoke. (I also carry a facemask respirator for the same reason).
