I have forced hot air heat, and the old Humidor humidifier (installed near
the furnace) is no longer working. I never liked it all that much,
anyway,
it was the old type with the rotating sponge, etc. So, now I am looking
for
a new humidifier. Any recommendations? Are the "mist spray" type better
than the rotating sponge one (I don't know the precise term).




Don't buy either! The water wheel type humidifiers are just a breeding
ground for mold. The mist units can cause problems with mosture rusting the
ductwork, plus the nozzles clog.

Aprilaire makes good units.

I have the Aprilaire 760 and its been super. Just clean it once a
season, which is a snap, as the whole thing just pops off, don't even
need a screwdriver. I went with it because of the fan and I preferred
not to bypass the air. I'm not real sure how much of a difference it
makes, but I can see two issues:

1 - Loss of some blower efficiency

2 - Now you have hot very humid air going directly back through the
heat exchanger. One would think this might lead to rusting of the
heat exchanger.
