A dehumidifier reduces the level of humidity in the air, usually for health reasons. Humid air can cause mould and mildew to grow inside homes, which pose various health risks. Very humid climates or air make some people extremely uncomfortable, causing excessive sweating that can't evaporate in the air that is already saturated with moisture. It can also cause condensation that can disrupt sleeping, or prevent laundry from drying thoroughly enough to prevent mustiness. Higher humidity is also preferred by 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.
This machine is used mostly in conjunction with mould remediation, but can also be rented on a per day basis.
