This is what happens when you cook without extractor hood. In the graph below you can see a huge spike on the PM sensor, this is because my extractor hood in the kitchen has broken and I had to cook without it. Immediately the air quality went down.
The air quality monitor was 2 rooms away from the kitchen, so always ventilate the kitchen by using an extractor hood. Tip by closing the lid of the pot/pan you decrease dramatically the release of PMs into the atmosphere.
