I'm in central NC, humidity is getting to be an issue now until mid/late October. My trains are in my shop which is very tight, housewrap/sheeting/closed cell foam/fiberglass/sheetrock.
I have mini split AC and heat and must keep dehumidifiers running, I like to keep at 40%. I read all about air exchange and get the principle, one thing no one mentions is pollen. Air going out from somewhere must draw air in from somewhere. What do you do about pollen? It has been so bad this year that there has been a yellow fog at times and after two hours outside, your car looks as if some dumped sulfer on it. I don;t use a fan or open windows anymore because of this knowing the house and contents would turn yellow inside.w is the pollen kept at bay when exchanging air?
How is the pollen controlled - kept at bay when using an air exchange system.
