Excess moisture in the air can cause substantial damage to items in your home and your health. A good dehumidifier removes excess humidity from the air, which can help prevent mold and mildew buildup and eliminate allergens. Dehumidifiers are often placed in basements, but there are other use cases for them, such as in closets where you store damp clothes or other smaller areas where too much moisture can cause a problem such as bathrooms, RVs, boats, and more.
Dehumidifiers fan-force air over coolant-filled coils to remove moisture. The remaining condensed moisture then drips from the coils into a bucket or basin, or it may be pumped out of the unit depending on the model. As a result, drier air is expelled back into the room.
Dehumidifiers: How do they work?
Extreme temperature cause many homes to experience high condensation levels, especially during autumn and winter. Moisture levels within the home also increase when we shower or dry our washing indoors – as a result of this, damp, mould and mildew build up to worrying levels. This is where a dehumidifier is an ideal solution. They work by pulling air in and running it past a cooling coil, which in turn removes moisture from the air by reducing the temperature.
