Get the Aprilaire with the fan. I tried the one without which connects to
both the supply pleneum and the return duct. It depends on differential
pressure to push air past the "media" and didin't work very well. For what
it's worth, the Sears model that used the sponge covered wheel, pushed the
most water into the air but the yearly maintenance on it was higher.

a new humidifier. Any recommendations? Are the "mist spray" type

than the rotating sponge one (I don't know the precise term).

I suggest neither. I suggest the Aprilaire models. Not only do I
have
one, but I chose it since so many people here and elsewhere have
recommended them.

Thanks. I took a quick look, and they have a few different models. 400,
550, 600, 700, 760A Other that the ratings, in terms of sq. ft., and the
fact that the 550 is manual, is the 700 series with the fan, better or
just
different? Which one did you get?
