Hoods

There are non-vented hoods. However before you go buy one, why do you want a hood?

No.

Don't be so lazy...

Hello Joseph Meehar, The reason i think i want a "hood" is because it is to trap the nasty grease that wouldhave traveled all through my house. So is that the right thing to do? Truly

There are, asMr. Meehan says, recirculating hoods. They are better than nothing, and much less useful than vented hoods. There are updraft and downdraft arrangements, if you need a path to the outside. TB

Right answer. You can use a ventless hood to do that. They are available most places where hoods are sold. I believe many hoods can be installed either way.

I think so too.

I have a hood without a vent, but the electrician who wired these town houses and also lived in one for many years put a vent in his house. One could see the exit above his front sliding glass door.

The seller told me how expensive the replaceable charcoal filters are, and they are, so I don't buy a replacement. The "spun" metal grill can easily be washed in he dishwasher though. But I don't fry and only broil, and don't use the fan much anyhow. So it doesn't get dirty. I don't like the noise (either high or low speed), but maybe newer ones are quieter.

The recirculating hoods that I have run into have all been pretty noisy and don't strike me as particularly effective. I don't do a lot of greasy frying but when I boil a pot of water and observe the "steam" there does not seem to be sufficient air flow to have much effect more than a few inches from the metal grill.

Of course these have all been cheap apartment or non-upgraded builder units, so I am sure better performance can be had. I would think though that if the OP is looking to ceiling mount a hood it would have to have a LOT of suction to have any effect at cooktop level.

While they can help reduce the grease, they will not remove any of the steam. Only exhausting outside will do that.

Exterior vented solves TWO problems.

I think you misunderstood what I am saying. I realize that the hood cannot remove the steam. The steam does however indicate that the hoods that I have observed create negligible draft more than a few inches below the hood and that most of the grease, like the steam, probably never enters the zone of influence of the hood.

I see. However my experience is that the steam, as well as the grease laden hot air tends to rise and most will go through the hood.

Note different hoods have different designs and those designs can effect the air flow patterns.
