I'm looking at installing a range hood soon and was curious about the ductless hoods. Do they work well? Not worth a hoot?
I could install a ducted unit, but to connect one to the existing exhaust duct would take a lot of tricky ductwork with short, tight turns. So if the ductless ones work well that would make my job that much easier!
Ductless, does work as long as you keep the filters clean, ductless requires a carbon filter in addition to a grease trap style filter. The carbon filters are about $30 and need to be replaced say annually.
Edit - the advantage of ductless other than the obvious reasons, is, you don't pump you conditioned air out of the house.
When its all said and done there is usually more said than done
If you can install a vent to outside, while maintaing spec's, you'll be much better off. it's also a one time thing. although the recirculated type will pick up some of the particulates it will still just dump the air back into room..
