We have a low attic. Neither of us is up to shinnying up through the access in the top of a closet and ploughing through the insulation and dust to cut a hole in the kitchen ceiling. We have a fan up there, which doesn’t do much of a job.

And broiling requires good ventilation. I managed to half kill myself. Note to self: cumin when incinerated produces a nasty smoke that kills your eyes. And the smoke kept coming.

That did it. I swore no more grilling until it’s warm enough outside to fire up the outdoor barbecue.

But now and again you just need ventilation in the kitchen. We thought of getting a screen door for the mud room outer door, but doors with screen doors need to open one inward, one out, and the floor of the mudroom has a slope that means the door would have to be jacked up with a nasty catch-you type sill.

We thought of getting one for the inner door, the actual kitchen door. But screen doors don’t come in interior-door sizes, unless you custom, which is spendy to the max.

Soooo…wall fan. We have space above the kitchen door to the mudroom. A trip to Lowes located a relatively inexpensive room-to-room fan kit that will go above the door (it’s 13 inches and we have 13 3/4 inches above that door) and blast air out into the mudroom, and on outside if we open the back door. No kitteh-escapes, and fast air exchange. A nice solution for the ventilation problem, an easy DIY (we cut the hole, watch out for the wiring, remove (probably) one short stud which won’t be load-bearing, possibly reinforce the opening by moving the stud or adding an L-brace—replace the box under the lightswitch beside the door with a duplex box, add a switch and wire going up to the fan—likely have to bore a hole in one short stud above the door to get the wire through, then fit the fan in, put the plate on the new switches, put the fan grille on both sides, and viola! Ventilation!
The Lowe’s department on these things is good: their display gives you the chance to hear a motor at 4 sonnes, at 3, and at 2. (Noise level). And this moves a lot of air, while being a bit noisy, but then, you don’t have it on except at need.

Anybody’s who’s got an airflow problem between two rooms, you have to ask about room-to-room units: they don’t have them displayed. But they exist, and are some under 50$. Great solution for a dead-end room.
