A dehumidifiers purpose is to lower and control the humidity in the air, thus eliminating odors, providing a more comfortable environment and decreasing the chance of mold growth. When humidity levels reach 60% and above in a home, mold growth is almost certain as well as other potentially harmful and costly issues. The ideal range of humidity within a home is between 35 to 45 percent. This will also limit populations of most pests including clothes moths, fleas, cockroaches, woodlice and dust mites. By their operation, dehumidifiers produce an excess of water which has been removed from the conditioned air. This water, usually called condensate in its liquid form, must be collected and disposed of, unless you’re equipped with a unit that is directly draining into plumbing or a sump pump.
Basements are naturally cooler than the rest of the house, which makes them subject to high humidity. Because the basement floors and walls are in contact with the soil, and soil temperatures several feet below the surface remain at a constant temperature of 50°F – 60°F or less, basement floors and walls tend to remain cool. Also, basements generally do not have many windows, if any, so there is little or no solar heat gain. Because cool air is dense, it is less capable of holding moisture, or water vapor, than warmer air. When the air temperature is cooler, it is not only denser, but also less “active.” Molecules in a less active state are more likely to be solid or liquid than vapor or gas. Therefore, since basements tend to be cool and colder air has less ability to hold gaseous water molecules — basements will have higher relative humidity.
Moisture is the most common problem in basements — either entering from outside sources or being produced inside by the occupants’ activities. The soil around the walls can contain a large amount of moisture from surface water that is seeping down or from a high water table. Water can find its way inside by gravity or through a crack or flaw in the water protection layer of the foundation. Water can also be pulled up by a “wicking action” or “pushed up” by hydrostatic pressure from the soil under the walls or floor.
Where Moisture Comes From
Air can leak into the home through walls, roofs, and floors and have damaging effects on a house. Uncontrolled airflow through the envelope of the home not only carries moisture into framing cavities, causing mold and rot, but it can also account for a huge portion of a home’s energy use and can cause indoor air quality problems. In a leaky house, large volumes of air – driven by exhaust fans, stack effect, and the wind – can blow through the floor, walls, and ceiling.
Diffusion Through Materials
This is a process by which vapor spreads or moves through permeable materials caused by a difference in water vapor pressure. An example of this is when the soil becomes saturated and moisture enters the crawl space through the walls by vapor diffusion. Installing a vapor barrier can help reduce the amount of moisture that makes its way into the crawl space and into the rest of the home.
Internally Generated Moisture
A family of four produces on average two pints of water an hour, or up to 25 pints of water a day, simply by washing dishes, taking showers, cooking, and breathing.
Symptoms of High Humidity:
- Wood rot
- Musty odors
- Dust mites
- Rusty ductwork
- Insects and pests
- Buckling floors
- Damaged cabinetry and other woodwork
- High cooling costs
- Wet insulation
- Sweating windows
Every one of these factors contributes to the damage and deterioration of your home property and valuable possessions. And, they all require very little to initiate, survive and thrive — moisture and condensation from high humidity levels for water, and an organic-based material for food (fabric, wood, paper, furniture, etc). It is no surprise that they are plentiful in humid environments. Cooler surfaces are especially susceptible because the relative humidity will be near 100%. These surfaces may even be visibly wet with condensation. For this reason, the EPA recommends keeping humidity levels below 50%.
These conditions must also be prevented in micro-environments such as underneath carpeting, rugs, or storage boxes. Mold, mildew, pests, and destruction of organic materials can be prevented or minimized in the home through humidity control that maintains reduced relative humidity levels and prevents cooler surfaces from becoming damp. To avoid the problems caused by moisture, and to create a comfortable, healthy and safe living environment, a dehumidifier is necessary to maintain relative humidity between 45–50% throughout the home.
The Santa Fe dehumidifier removes odor-causing moisture and maintains EPA-recommended relative humidity levels of 45-50% which are ideal conditions for an odor-free storage space or comfortable living space for you and your family.

Disclaimer: Free Delivery is for all customers within our service area. Deliveries outside our service area will come with fees. Installation and set up requires a proper dedicated outlet and drainage line for the unit, both of which must be supplied by the customer/home owner/landlord. We do not install any electric, or do any plumbing work. Check your local municipalities for regulations and laws concerning electrical and plumbing needs. If proper electric and plumbing is available, we will set the unit up, but further maintenance, care settings are not our responsibility.
