Steam vs hydro air for allergies
My wife's allergies seem to act up every time we turn on our steam radiators. A pro once explained that the radiators may push out dirt (rust, other particles from the old pipes) that could be causing the allergies to flare up. I'm considering switching to hydro air as we could add filtration and potentially improve the situation, but from what I read, forced air (including hydro) may actually increase allergies due to the ducts gathering dust and other unsavories, and due to the dust that can be kicked up by the air streams.
Has anyone converted from steam to hydro air to deal with allergies and what has been the experience? Any other words of wisdom (other than the usual "you'd be crazy to get rid of steam no matter what").
