Unfortunately, this is not simple to rectify. My previous house was expensive and difficult to retrofit to have an externally vented range hood, and I'm renting now, where basically nothing has externally vented range hoods, and looking to buy a place that does. This is a hard non-negotiable requirement for my next house, but the pickings are very slim. This is a severe issue (in the US anyway), and it's difficult to retrofit for most kitchens since most houses in the US are designed with the stove on the interior wall rather than the exterior wall.
Cooking fumes are the primary pollutant in my life, and honestly is one that I struggle with since I have severe asthma but love to cook. I do what I can, but this is something I wish was taken more seriously in society because there's a huge economic hill to climb to solve it yourself vs having to deal with what's available on market.
While it's true that gas stoves are a significant source of kitchen fumes, they are not the only source, just the act of cooking food produces fumes. As an example, when searing meats, significant amounts of fumes are released, as is also the case when bringing anything beyond the boiling point, steam is given off, and steam can contain other particulates. Just using an electric stove (which I use currently in my rental) alone does not solve the issue, and is not even that large of a reduction. Most of the fumes from cooking are from the act of cooking, not from the heat source.
I have an induction cook plate and the AQI indoors still goes in the hundreds when cooking on it. It takes about fifteen to thirty minutes of the air purifiers running at full blast to get down to single digits AQI.
The last place I lived-in had a hood over the electric stove/oven. The exhaust-port included a steel-mesh grease-filter before the fan. Then the exhaust entered a zinc-coated-tin (?) duct about 6 inches in diameter and 10 feet long. It travelled straight above a row of cupboards to a side-wall and to the outdoors ... exiting through a louvered vent.
I suspect such a setup doesn't have to cost much. In return I enjoyed many years of cooking, summer and winter, without mostly without the odors & humidity.
I missed it as soon as I moved here ... although the vent is up-through-the-roof vertical, it's very ineffective ... and I can no longer cook most things I once took for granted.
