vent for a microwave?

[Polar Sparky 1224]

My dad wants to vent an undercabanit microwave through the wall, is it okay to have a screen over the vent to keep insects out? I am thinking it is fine since it only blows out hot air, and the filters remove a lot of the airborn particles.

yes you can put a screen on it a microwave it does not exaust out things like a dryer ,it is just heat. this is the same as a stove or oven exaust ,it is for heat and smoke.

Here's another tip. If you are venting smoke out of your microwave don't "nuke" the marshmallows for so long!


(just couldn't resist as my son "discovered" the microwave over the weekend.....)

Pick up the correct through the wall vent at HomeDepot. It has a spring flap on it already. It's approximately 3" X 14". You must rotate the blower on the microwave so it blows out the back. It then does not go through the filter (except for the lower remove-to-clean ones. Make sure he properly seals the vent to the wall to preclude grease from entering the wall cavity. I've found the foil type duct tape works best.
