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.
