Moisture is all around us in the air; we only tend to notice when it is at extremes—either too high or too low. When there is significant moisture present, we perceive it as humidity. Beyond making your home feel stuffy, high humidity can have a negative effect on electronics, fabrics, and interior surfaces. Unchecked wetness in the interior of a home can cause a lingering, musty smell; mould growth; and potential respiratory illness. Studies show that irritant organisms (bacteria, viruses, mites, and fungi) can thrive when the surroundings are damp, leading to the development or aggravation of respiratory problems like asthma and allergies. A dehumidifier is an appliance that is used to reduce the moisture content of a room’s air, preventing dampness from building up. Check out this informative video describing a mini dehumidifier for use in small areas like closets and basements.
The mechanism of a mini-dehumidifier involves air intake, the removal of moisture, and return of the air back into the space. The collected moisture fills into a small internal chamber that can be removed and emptied periodically. Mini-dehumidifiers are meant to be used in small enclosed spaces like the bathroom or near a small area of water infiltration. Removing the water from air can occur by one of two ways: refrigeration or absorption/adsorption.
Refrigeration, as the name implies, uses a method similar to refrigerators. Warm air that is coming into the machine is cooled to remove the moisture. An electric fan pulls the air in and over very cold coolant-filled pipes. The coolant circulates within the pipes. The channelled air begins to cool and moisture (in liquid form) drips downward into the collection chamber. The air is then passed over a heating element to bring it back to ambient temperature. This dry air is blown back into the room. As the collection chamber reaches its maximum level, a shut-off is triggered that disengages the fan and indicates the need to empty it.
Other mini-dehumidifiers work by ventilation—they don’t actually dehumidify, rather they draw in cool air from outside, which displaces the stagnant air inside. Using the machine to aid in air exchange can make you feel comfortable and mitigate the growth of harmful organisms with greater efficiency than normal unaided air movement. These dehumidifiers are excellent for use in homes where efficient home sealing has impeded the air exchange between inside and outside.
A small portion of mini-dehumidifiers work via absorption/adsorption. They actively pull in moisture from the air by absorption and then pull away the water by adsorption. The process begins when moist air is funnelled into the dehumidifier’s intake duct. The air passes over a large moving wheel comprised of water-absorbing material, which draws in the moisture from the passing air. The de-humidified air is carried back into the room with the help of a fan. Below, a heating element warms the interior chamber. Humid air passes through. The desiccant wheel rotates in the heated area, giving it the chance to dry. A fan helps to expel the hot, wet air via an exhaust duct.
Reasonably, you may need to purchase a humidifier if/when you have leaks, water infiltration, damp weather, or any number of situations that can cause excess moisture to linger in your home. A mini-dehumidifier is a good option in small spaces because the units themselves are quite diminutive. A small model has the capacity to dehumidify contained areas of moisture like bathrooms, kitchens, or even closets (where clothes can begin to get musty and grow mould due to stagnant, long-term moisture). Besides preserving your home’s surfaces and items, your mini-dehumidifier can make the air feel fresher and more comfortable, even lowering the incidence of respiratory irritation and illness. When shopping, be sure to look for a mini-dehumidifier that is appropriate for the room size and specific situation you intend to use it in, to achieve the maximum benefit.
