What is relative humidity and how do I measure it?
The amount of
water in the air versus the amount of water it could hold if it
were saturated. It is expressed as a percentage (%). For example,
at 70F, saturated air has over 1 pound of moisture in 1000 cubic
feet, which is 100% relative humidity. At 50% relative humidity,
only one-half the amount of water is present. A measuring device
called a hygrometer is available through local retailers to
measure the relative humidity level in your home.
Where should I place the humidifier in my home?
Place it on any
inside wall away from obstructions and as close to the cold air
return of your furnace as possible for the best operation.
Where should I set my humidifier's humidistat?
Generally set
the humidistat in the medium range (30 – 50%RH) or at a level that
maintains your personal comfort.
When do I have too much humidity?
You will notice
water droplets (condensation) forming on the inside of your
windows. Turn your humidity level down. As the outdoor temperature
increases, a higher level of indoor humidity can be maintained.
Conversely, as the outdoor temperature decreases, lower levels of
indoor humidity can be maintained before condensation occurs on
your windows.
How often should I change my filter?
As the filter
gathers impurities you will notice it begin to discolor. When the
lower portion shows distinct disc-coloration, it's time to change
your filter. Generally filters should be replaced at least once
during the season. This will vary depending on the amount of
solids in your water.
How long should my humidifier run?
Your humidifier
could run constantly for up to 24 hours at the beginning of the
heating season to reach the desired relative humidity in your
home. Once that level is achieved, the automatic humidistat will
control the on and off cycling of your humidifier. Generally
speaking, the colder the outside temperature, the more often your
unit will run.
