I want to install a supply ventilation system in my home. As it isn't exceptionally tight, the positive pressure would do me good in terms of minimizing untreated air infiltration.
My problem is I need any incoming air to be filtered, and, for half the year, dehumidified. The current simplest method appears to be throwing an aircycler on and connecting to furnace. I have a good filter on my air handler (an entirely different discussion.) I still would likely need to dehumidify the air as it comes in. That's scenario 1.
What I would prefer is a simple dedicated system. I'd like a central fan, small ducts, and an outside supply that runs through a good filter and gets dehumidified. In that case, I'd just bring in 100cfm continuously. Scenario 2.
I'm aiming for efficiency if possible, but really am going for air quality above and beyond everything else. I have treatment resistant asthma with sensitivities to things in my crawl and things outside in Spring. If I could get constant ventilation of fresh air, and get a little positive pressure going, it should help a lot.
Can anyone recommend a simple system for this?
Can anyone recommend one that works separately from my furnace fan?
