Thnx. The A/C draws air from the outside. No recycle air is available on the small unit. Space is 3'x6'x7'. I had to install a flat carbon filter on the unit, because it exhausted alot of smell. I have an old 4" duct fan, used in the old room, but didnt want to cut any more holes than I had to.
BOYZNUS Reviewed by BOYZNUS on . Vent in and out question I just built a new flower room. I didn't put in any intake or exhaust vents,,, because I have a 5000 btu air conditioner installed. Will this replace enough air, or should I still install vents?. I don't want the vents to undermine the work of the A/C. Think this might be a prob?? Thnx P.S. Look!!!!!! My caps lock button is fixed!!!! Hurray!!!! Rating: 5
