it is a vent that is in the center obviously
Air conditioners generate a lot of heat, so normally it would be counterproductive not to vent them. However, dehumidifiers are basically air conditioners that are not vented. Although they force water out of the air by cooling it, I learned from personal experience that they (or at least the model I had) heat an area more than they cool it.
The air from the vent should be 18 to 22 degrees F lower than the temperature of the air going into the return.
You need a filter retainer
Some what but if you have a large hair dog, you need to filter each return vent to keep dander out of furnace ducts
