What's Hidden In Your Crawlspace Will
Eventually End Up In Your Home...
Your home is constantly filled with tiny, invisible mold spores that
float through the air. These spores are the main cause of allergies.
An untreated, vented crawlspace is an air quality disaster waiting
to happen. The bare earth under your home contains high levels of
moisture. Natural airflow patterns, called the “Stack Effect” draws
the air from the crawlspace upwards into your home. This air brings
with it not only mold spores that can affect your health, but also
moisture that enters your floor framing system, opening the door for
home has vents in the roof allowing warm air to escape. Warm air
inside your home is always rising and slowly escaping through your
roof vents. In return, air is sucked up into your home from the
crawl space beneath. Humidity in your crawl space allows mold to
grow into colonies and release spores. In a crawl space with a
humidity problem, you will find a metropolis of fungus constantly
spewing out spores, day and night, all year long, that are sucked
upward and distributed into the home's living area.
Where There is Moisture, There is Vermin... Spiders, snakes, centipedes, silverfish, cockroaches, rats,
mice, tiny dust mites and termites all love living in the shady,
damp crawl space under your home. Wood floors and floor joists often
fall prey to moisture damage. Floors squeak and warp, support beams
rot and all that moist wood makes ideal food for termites. Moisture,
dirt, dust mites and particles from the unhealthiest part of your
home are sucked up through your floors and pass through your entire
house. This is the single biggest cause of indoor odors and
should also know that humidity in the crawl space leads to humidity
throughout the home, which leads to dust mites (another big allergy
& asthma trigger). A home with mold problems is likely to have dust
mite problems as well. Similar to mold, dust mites lay dormant until
favorable moist conditions allow them to thrive. Humidity provides
the water source for a slew of microscopic (and larger) organisms
that live in your crawl space and walls. An entire food chain of
organisms exists within your home with microscopic organisms at the
bottom and larger ones, like spiders and mice at the top. All of
these organisms are known to contribute to poor indoor air quality

And So We Began The
Search For A Crawl Space Dehumidifier That Can Do The Job...
Are you one of the many people who have wasted money on a
dehumidifier that did not last through one season?
We've heard endless complaints about units made by well
known, "so-called" quality brands that just end up freezing
in moderate temperatures, the coils can cover with ice and
shut down that ultimately lead to the demise of your
You've got to be careful when choosing a crawl space
dehumidifier. Nothing you buy at your local home
improvement store will do the job. These units commonly
sold in stores are considered appliance grade
dehumidifiers. They may work in a living room or
bedroom, but will not last one cold, rainy night in your
Even most units sold as crawl space dehumidifiers fall short of
ideal. Some can work in temperatures as low as 50
degrees which may be fine for a basement, but out in your
crawl space, it is not a year round solution.
We have tested the majority of crawlspace dehumidifiers on
the market and we could not find one that we could ethically
endorse with good conscience. Our research demonstrated that
there are many dehumidifiers that are being marketed with
"exaggerated numbers" -- such as pints of moisture removed
per day and energy star ratings.
So, what can you do?
Well... if you are a company with contacts in air quality
equipment manufacturing, you can have a unit custom made for you.
Of course, most people aren't in that situation...
Fortunately we are... so that's exactly what we did!
We Decided To Manufacture Our Own Line Of
OscarAir, Inc. is a company with the
primary purpose of sourcing the best value in various categories of
dehumidifiers and other air quality equipment.
What sets us apart from other crawlspace dehumidifier websites
is that we are comprised of solution oriented air quality
professionals. We're not here to just sell you equipment. There
are plenty of “catalogue” websites out there for that. We
actually enjoy helping people solve their air quality problems.
Generally what happens, after people shop around and do their
own research, they come to us to learn a great deal more. We
educate people about the science of dehumidification so you can
make informed decisions about your air quality issues.
However, when it came to solving crawl space
humidity, the ideal equipment to correct the problem did not
exist! It has got to be the right size, have the correct
dehumidifying capabilities and be priced right for cost
conscious homeowners. Since there was not a unit on the market
that stood up to our stringent requirements, we had a crawl
space dehumidifier produced based on our specifications.
This is a unit we can

What Size Crawlspace Dehumidifier Do I Need?
Here's what most people don't know about choosing the right dehumidifier
for a crawlspace. Most people only go by pints removed per day... THIS
CAN BE MISLEADING. What's just as important is airflow ...this is where
other crawlspace dehumidifiers fall short. Airflow tells you how
powerful the fan is, measured in CFM (cubic feet of airflow movement per
minute). Measuring the airflow by CFM determines how many times all of
the air in your crawlspace can pass through the dehumidifier each
minute. To effectively dehumidify your crawlspace, all the air in your
crawlspace must pass through the dehumidifier 3 to 6 times every hour.
To size your
equipment properly, find your current crawlspace moisture level and crawlspace
size. Moisture level can be measured as relative
humidity with an inexpensive humidity sensor, hygrometer or
estimated using this table. Humidity levels vary from
day to day, though you should be aware if you live near
water or a known humid geographic area. Click the map
below to see today's humidity levels in your area.
Take your ACH (air changes per hour) and put it into the
formula below to find your required airflow in CFM.

feels and smells wet. Leakage visible, mold and mildew
is present on surfaces. Crawlspaces that are not totally
enclosed can go in this category.
Crawlspace area has standing water
present, or is waterfront property.
Now that you know your CFM requirement, choose the right size and
number of dehumidifiers to obtain your CFM. It's OK if your
unit has a little more power than what you need. That just
means it will run less often and use less electricity.
Once you have satisfied your CFM requirement, make sure you have
approximately enough pints per day. This table below is based off
Energy Star data. Find your square feet (not cubic feet) in the
left column and slide over to the appropriate humidity level to reveal
your necessary Pints Per Day.

Proper Crawl Space Dehumidifier Installation
For maximum efficiency, the proper installation needs to be followed. In
some situations, an oversized dehumidifier can compensate for lack of
crawlspace preparation. Here are our recommended steps to prepare your
1. Close vents.
2. Identify and eliminate sources of moisture.
3. Seal with plastic vapor barrier.
4. Install dehumidifier.
Despite outdated government codes that require openings for every crawl
space, contractors and air quality professionals working in the field
every day have learned that the best way to control humidity is to
seal the crawl space. The first thing to do is to go close your
crawl space vents. If you have dirt or gravel at the bottom of your
crawl space, that's ok. Though you may want to remove any debris,
building materials or random junk that somehow ends up in your crawl
space. This next step is highly recommended: use plastic sheeting
(minimum 4 mil thickness) to cover the ground and seal part way up the
walls of your crawl space. (In new construction, this is called a vapor
lock or vapor barrier.) Finally, the crawlspace dehumidifier can be
strapped to floor joists or rest on a cinder block. Be sure to run the
drain hose down and out of your crawl space and away from the foundation
of your house. A condensation pump is available if you need to run the
hose up and over any obstacles.
About Energy Star Ratings
you like saving money on your energy bills? Our Energy Star (application
commercial grade dehumidifier will outperform any Energy Star rated
appliance grade dehumidifiers you can find at any local retail stores.
Energy Star ratings are generally used for residential or appliance
grade dehumidifiers, which are intended to operate in a room at 80°F.
This is also consistent with AHAM ratings. These commonly found Energy
Star rated dehumidifiers only work efficiently in ideal conditions. As
temperatures drop, so do most other dehumidifier efficiencies.
A crawlspace provides far from ideal conditions. Your crawlspace is the
most humid and usually coldest place in your home. Using an appliance
grade dehumidifier from a local department or home improvement store in
an environment for which it was not designed, will work its little
compressor harder and longer than was ever intended - eating up your
electricity far beyond your worst appliances. If you don't believe us,
buy one and watch your energy bill skyrocket. Then come back here and
get a workhorse built for harsh crawl space environments.
As for Energy
Star compliance? Dehumidifier energy efficiency is measured in
liters of water removed per kilowatt-hour of energy consumed. Both Dri-CrawlSpace® dehumidifier units are well within Energy
Star compliance guidelines of 1.20 - 2.25 Liters per Kilowatt-Hour!
