Do they make a window air conditioner that doesn't let all the little nit flies through it? I have no leaks around the sides, top or bottom. I also have the space between the sashes covered. The only way they can get in is through the intake outside and through the other side into the room. I tape a screen over the intakes outside and this year I put a screen over the cooling vents. One nit fly so far.
I've had different brands an never had that problem with any of them
Lately I need to modify and "fix" things like this so they work properly. I've put my own screen over things like this to prevent similar problems.
Can they come in through a drip/drain hose?
My window unit (it cools only the bedroom - installing it cut my power bill by 2/3rds) has no path for that noxious "outside air."
If yours has an "fresh air" setting, turn it off. In the alternative, I suppose you could jury-rig a filter on the output side.
