It's funny, we spend all this time trying to tighten up our home's building envelope and we never think about the problems that this may have on our homes internal environment. Things like radon, micro bacteria, allergens, sickness, smells, viruses and who knows what else ends up being trapped in our homes. I now that when spring comes around I take every opportunity to open up my windows in order to let in the fresh clean and refreshing air and let out the stale, stagnant air. This is something that just isn't possible during the winter months but heat exchanger is the answer to that.
