Home Dehumidifier: Small, Basement, Whole House

Are you searching for the right home dehumidifier to keep your house dry?

We have researched home dehumidifier products and can help you find the best dehumidifier for your house, whether you are dealing with indoor humidity or need to undergo mold remediation.  The first factor to look at is location.  Depending on where the humidity is in your home, you may need a small dehumidifier, a basement dehumidifier or a whole house dehumidifier.

If you have pockets of moisture trapped in isolated areas, such as musty closets, moldy bathrooms, or temporary humidity in a bedroom, check out our portable & small dehumidifiers.  If you need to condition an entire basement, crawlspace or attic, look at our basement dehumidifiers.  For treating every floor and room of your home through the HVAC system, browse our whole house dehumidifiers.

Small dehumidifiers lend themselves well to removing moisture in enclosed parts of your home that receive little ventilation, like closets, bedrooms and bathrooms.

Small Dehumidifiers

Do you spend time in an area needing mold remediation? Mold growth is enabled by indoor humidity.  A portable dehumidifier can offer allergy relief by lowering relative humidity, which stops the spread of new mold and helps kill existing mold.  An air purifier will remove spores from the air. If people will be living or working in the area, dehumidification and air filtration should be used before and during mold remediation.

Do your allergies kick in during 70 rainy weather?  When the air conditioner is not running, there is nothing to control indoor relative humidity.  Sleeping all night through damp seasons with no air conditioning or dehumidifier exposes you to microorganisms that trigger allergies and asthma.  When relative humidity is above 55%, dust mites become active.  A portable dehumidifier that you can pull out and roll away after the weather changes can be just enough dehumidification to protect you during the night.

A closet is an incubator for mold and fungus.  Shoes retain moisture.  With the door shut, warm air and moisture cannot escape.  Once it smells musty, a colony of  fungus or mildew has established itself on contents of the closet.  This is an ideal situation for a closet dehumidifier.

Is there mildew or mold growing in your laundry room, on bathroom tile or shower curtains?  Mildew is a common fungus.   Airborne spores constantly drift though indoor and outdoor air.  In dry conditions the spores are dormant.  When they land in moisture, they grow and produce a colony.  This is what you find in your bathroom and above your washing machine.  The colony produces more spores that float around your home, looking for humid conditions.  Soap scum, mold or mildew is a sign that your bathroom does not have adequate humidity control.  A portable or bathroom dehumidifier can regulate moisture conditions and prevent colonies from forming.

Do you keep valuable items in your home?  A piano, guitars, other musical instruments, RVs, boats and even guns are sensitive to humidity.  If you have a music room or gun safe in your home, be sure the humidity in that area is controlled.  In humid areas, a small home dehumidifier may be necessary to help your piano, guitar, RV or gunsafe dehumidifier.

Various Basement Dehumidifiers

When choosing a basement dehumidifier, consider the size of the area, the lowest temperature your basement reaches and the severity of moisture problem.  You should also plan where in the basement, attic or crawlspace to put the dehumidifier and where condensate can drain.

Need help choosing a dehumidifier for your attic, basement or crawlspace, see all our basement dehumidifiers.

Basement Dehumidifiers

What is considered a basement dehumidifier?  In our line of basement dehumidifiers, we include stand alone units able to condition large, high humidity areas.  Some of these units can be hidden in a utility room and ducted into the finished portion of your basement.  They can also be used for attics and crawlspaces.  Most of these basement dehumidifiers simply plug into a standard outlet and condense water into a container or hose you can route to a drain.

Why is your basement cold, damp and a little creepy?  Lets look at an example of weather conditions on a warm summer day.  Let's say it is 83F outside, 50% relative humidity, specific humidity 0.012lbs, and dew point at 62F.  Ground temperature is typically 54F, keeping your basement 62F.  Moisture from outside enters the house and equalizes throughout all floors of the house.

So why is the basement so humid?  The weight of water found in a pound of air, expressed as a decimal (e.g., .012lb.) is called specific humidity.  This is how much water is in the air.  You can think of relative humidity as percent occupied in relation to maximum capacity.  50% RH means the air is holding 50% of its water holding capacity.  Relative humidity is effected by temperature.  Colder air can not hold as much water.  As temperature drops, relative humidity rises.  Dew point is the temperature where water will condense or fall from the air.

With ground temperature keeping your basement cold, relative humidity increases.  In areas under carpets and boxes, water will condense - allowing mildew, bacteria and dust mites to thrive.  These moist conditions are also ideal for spiders, silverfish, centipedes and other bugs that make basements creepy.

Removing specific humidity from your basement air eliminates the water source for mold, fungus and bugs.  A basement dehumidifier should maintain 50% relative humidity regardless the temperature of your basement.

Whole house dehumidifiers integrate into your HVAC and dehumidify your entire home's indoor air from the basement, attic, utility room or crawlspace.

Research further on central dehumidification and browse our whole house dehumidifiers.

Whole House Dehumidifiers

Do you want a dehumidifier that stays out of sight and regulates humidity all year long?

In whole house dehumidifiers, a centrally located humidistat monitors humidity levels and turns on or off the system in order to regulate EPA recommended 30%-50% relative humidity.  Whole house dehumidifiers use ventilation to distribute the structure with comfortable dehumidified air.  Dampers and vent design allow appropriate airflow to problem areas.

Whether it's new construction or an existing home, a whole house dehumidifier can install into your HVAC forced air system.  Our whole house dehumidifiers range in capacity and sophistication to handle everything from a small house up to fully automated, light commercial buildings.

We have made choosing a whole house dehumidification system easy by searching out the best value in efficiency, reliability, customization and control features.

Any of our whole house dehumidifiers can be installed into your home's supply air just after the air conditioner coils.  Vertical and horizontal units can fit your attic, crawlspace, utility room or basement.  We offer manual and programmable digital controls for humidistat, fan, make up air ventilation and particle filtration.
