Why
Humidify?
Studies have estimated that most
people spend as much as 90% of their time at home
indoors. There’s
a reason to be concerned about indoor
air quality.
When cold, dry air enters your home and our home
and is warmed to room temperature, the relative
humidity in the average house can drop to as little
as 5%. Compare that to the average 25% relative
humidity of the Sahara Desert and you can understand
why the air inside your home can seriously affect
your health and comfort.
How Does Humidity Affect My Comfort?
Since the
air in your home is always trying to reach its
saturation point, it will absorb water wherever
it’s found. That means it is stealing
moisture from the bodies of you and your children,
your pets, your furniture and even your house plants.
By giving up moisture to the air, your skin, throat
and nasal passages dry out and crack, leading to
various physical discomforts. That's why many doctors
recommend humidifiers for allergy and asthma sufferers.
Research has shown that 30%
- 60% relative humidity is ideal. Outside this range, bacteria, fungi,
viruses and mites thrive and multiply. As these
creatures increase in number, so does your risk
of being adversely affected.
How Does Humidity Affect My House?
Virtually everything
in your home made from wood contains some moisture.
As dry air sucks that moisture out, the wood shrinks
and cracks. Harwood floors separate at the seams,
furniture shrinks and cracks, and doors warp and
no longer fit their frames as the moisture is drawn
off.
Are There Any Other Benefits To Properly Conditioned
Air?
Yes, it can help you save
energy! Warm, humid
summer air feels hotter than it actually is because
of the moisture it contains. That some principle
applies to your home in the winter. By keeping
the relative humidity inside your home at an ideal
level, you can turn your thermostat down a few
degrees and still feel comfortable. Dialing down
your thermostat just three degrees can reduce
your heating bill by as mush as 5%.
Operating Principal of Humidifiers
When the humidistat
senses a need for additional humidity, a solenoid
valve is opened and metered water flows into the
patented distribution tray at the top of the humidifier.
The tray assures that the evaporator pad is moistened
thoroughly and uniformly for greatest evaporative
efficiency.
Dry air, warmed by the furnace, is passed through
the wet pad where evaporation occurs and moist,
humidified air is circulated through out the home.
Unevaporated water drains from the bottom of the
unit carrying off troublesome minerals. The efficiency
of design ensures more water gets into the air
listed or running down the drain. The humidifier
uses less water input to produce more humidity
output than most competitive units.
A Smart Humidifier – The
NEW E1 Electronic Humidistat
With standard mechanical humidistat,
when outdoor temperatures fluctuate, frequent manual
adjustments are required to maintain the balance
between proper humidity levels in the home and
prevention of condensation on you windows. The
new E1 Electronic Humidistat automatically checks
the outdoor temperature through and external sensor
and adjust the humidity level in the home for optimal
performance. With the 1042DM and the optional E1
Humidistat, there’s no
need to worry about the weather, just set it one,
and forget it.
If it’s impractical to connect the outdoor
temperature sensor, the E1 can be used in manual
mode in the same manner as a standard humidistat.
How
Much Humidity Does My Home Need?
How much humidity your home need depends
on its size and construction, which
affects the number of air changes experienced per hour. The more frequently
the warmer air in your home is replaced by colder, dried outside air, the greater
need for humidification.
The Air
Conditioning and Refrigeration Institute,
a non-profit trade association, developed
and published the guidelines used
by most contractors today. The guidelines
classify home construction as “tight”, “average”,
or “loose”.
- Tight homes have
insulated walls and ceilings,
vapor barriers and weather stripping
around windows and doors. Windows and
doors fit snugly and the fireplace has
and effective damper. A tight home
experiences about ½ air change
per hour.
- Average
homes have insulated
walls and ceilings, vapor barriers
and a fireplace damper but loose
storm doors and windows. Average
homes experience 1 air change
per hour.
- Loose homes have
little insulation, no vapor barriers,
no weather stripping and no storm
doors or windows. These homes typically
experience 2 air changes per hour.
If you know the size of your home,
you can evaluate its construction and
refer to the chart for good estimate
on how much capacity your humidifier
must have.
Heated air often lacks the necessary
moisture to keep your skin soft, your
furniture and woodwork from cracking,
and your home static-free. The break-through
technology featured on Aprilaire -
the world's first completely automatic
humidifier - uses your heating system
to automatically distribute safe, comfortable,
humidified air to every room in your
home. |
