In cold weather the humidity in my house seems to range from 20 to 35 %.
I've heard that the comfort level can be improved with a humidifier
allowing the thermostat to be lowered somewhat. There are many on the
market with claims of providing better humidity throughout the entire
house but these are stand alone units and I kind of doubt the claims. It
would seem to me that there are units available which connect directly
to the furnace and the water supply. I would prefer something like that
rather than hire an illegal alien to keep a stand alone unit filled with
water. Those things only have a 1 to about 3 gallons capacity.
Can anyone enlighten me and/or make a suggestion for a forced air
furnace or a standalone?
BTW What should the humidity comfort level be for a home? Any info
It all matters with your location(climate), house air tightness, etc.
Maximum humidity you can allow is to a point of fog almost forming on
When you say cold I don't know how much on thermometer. Where I am,
it's around -20C and we have very dry climate. At -20C I maintain R.H.
of 20-30% in my house. If I raise humidity higher than that, windows fog
up. Popular power humidifer is Aprilaire which comes in different models
to fit the size of house. I use spray nozzle type controlled by furnace
blower power and humidistat.
Weather here is usually teens to 40s F during coldest months but dips to
single digits and below often. A rather wide range I suppose for the
Ohio valley. Humidity outside varies since weather comes from both the
north and the south.
I never thought about inside fogging. I never see it around here because
I doubt most don't use humidifiers.
Am I trying to fix something that's not broke?
When you don't feel comfortable indoor, lots of static on your clothing
and hair, dry nose, etc. are typical sign of too low R.H. Out here,
without humidifier in winter, it can cause nose bleeding, static, higher
heating cost, etc. Believe or not, w/o proper humidification, hygrometer
can register negative R.H.(pointer going below zero) here.
proper humidity in colder times of the year , can and does greatly increase
comfort ,and health issues , since humid air tends to retain its heat ,
it makes sense , that you would "feel" warmer ,
thus allowing for a lower setting on the tstat,
tony touched on , it , dry scratchy throat in the mornings, static electricity
when touching doorknobs? , noseblleds ? chapped lips ?
these are all indications of lower humidity ,
and a further indication, that you could benefit from a humidfier
i recommend a pulse type humidifier , uses a single orifice mounted in the
plenum, and has only one moving part , the solenoid itself ,
has a small logic board , and has the capability to run the furnace blower
independently of the heating cycles to add needed moisture if need be ,
you still havent told us where you are , it does matter !!!!

I agree with everything everyone has said about humidity (excpet the
comment about neagative RH.) and I have tried humdifiers and I find
the major issue in choosing a humdiifer is how does it deal with the
minerals in the water.
Some of them spray water into the air and you get a fine mineral dust
on everything in the house.
With some furnace units, the minerals collect in the plenum, thats not
Some of them the minerals collect in the humidifer on a pad and it has
to be cleaned regularly, a pain but not too bad.
Some of them have a water flow through where the excess minerals are
carried out in the waste water.
How does the pulse unit deal with the minerals?
I'm south of the Ohio river about 40 miles east of Louisville. The pulse
type humidifier sounds good and I do have those symptoms although at
times (depending on the weather) they are not as noticeable.
If you have fossil fuel heat, use a model that uses outdoor air for
combustion. Without such "sealed combustion" air must enter the house
to make up for lost air up the flue. This infiltrated make-up air is
dry, but the air that goes into the furnace/boiler is moist. Adding a
humidifier only replaces the lost moisture but does not eliminate the
loss. Eliminating the loss by using a sealed combustion heater is
often sufficient to maintain reasonable humidity from the common
household moisture sources alone.
