The hood is mostly important for capturing the vaporized grease and making sure it doesn’t get stuck to the ceiling in the event that your fan isn’t strong enough to keep up with sudden flared ups.
The most important thing for air quality is just how many cubic meter/feet your fan can vent put of the room. As long as it is strong enough to create a draft large enough for the size of your room you should be okay. Hood is for larger particles that the fan can’t move quickly, the volatile chemicals are smaller and should be mostly going up towards your vent as long as it’s placed close enough or is strong enough.
For a stove top, or like a stand alone device?
I mean… It is, especially depending on what and how much food you are cooking.
Making a “killer fried rice” isn’t the end all be all of wok cooking. I have had plenty of white people make what they claim is great fried rice that is greasy dog shit because they can’t get their woks hot enough.
As someone who grew up in Chinese restaurant kitchens… I can assure you a flat bottomed wok on an induction stovetop is never going to be adequate for traditional Chinese cooking. If there is an induction plate shaped to fit a round bottom wok and you could rock the wok on without damaging it…that would be a different story.
Until then I’m going to stick to using my outdoor burner, especially considering that the only electric utilities I have access to are already created with natural gas.
