Frequently Asked Questions

What does a dehumidifier actually do?

When excessive humidity becomes an issue in an indoor space, you will start to feel rather uncomfortable sitting it that area as the environment becomes muggy. Furthermore, the risk of mold growth exponentially increases, a “guest” you surely do not want to make an appearance. In excessively damp rooms and environments, the dehumidification system plays a crucial role as it helps reduce moisture and maintain healthy, adequate levels of indoor humidity.

At what level should relative humidity be kept?

For most indoor spaces, the ideal relative humidity should range from 45 to 50 percent. If relative humidity drops below 30 percent, your health is directly affected as issues like irritated skin, irritated respiratory passages, and the increase of flu viruses occur. However, relative humidity levels above 50 percent are just as harmful, if not even more dangerous. As high humidity becomes an issue, the environment becomes prosperous for mold and mildew growth, and the spreading of bacteria.

What are the dangers of high indoor humidity?

As aforementioned, high indoor humidity leads to mold growth as the environment creates proper conditions for the appearance and spreading of this dreaded fungi. For people who suffer from allergies or asthma, the presence of mold spores in the air they breathe presents a great threat to their health as these afflictions are affected by fungi spores. Furthermore, inhaling these spores is dangerous for clinically healthy people as well as they cause the contamination of respiratory tracts and lungs. Besides directly presenting a threat to your health, high indoor humidity is dangerous when it comes to the structure of your house and the state of wood furniture pieces as well, deprecating their quality.

What happens to the water collected by the dehumidification device?

Most dehumidifiers feature manual water removal in the form of a collection bucket where the water is automatically stored during the operational process of the appliance. When this bucket is filled, the dehumidification system stops working until you empty it. Other types of dehumidification systems offer the possibility of continuous drainage with the help of a hose which transports the water collected to an external container like a drain or outside of a window. Obviously, it is a lot more convenient to opt for continuous drainage as you will not be required to monitor the device and do any maintenance work on it from this point of view.

How long does it take for a typical dehumidifying appliance to considerably lower humidity?

The answer to this question depends on the size of the room/area the dehumidification appliance is placed in, as well as the device’s capacity. In a medium-sized room/area, it should take approximately 8 hours for a 30-pint dehumidifier to bring humidity levels down to 50 percent if they were above 70 percent before the appliance’s operation commenced. However, if we are talking about a damp building, it could take more than a week for the device to bring humidity to a healthy 50 percent.
