Frequently Asked Questions

Are you looking for a dehumidifier to help with your dry skin? 

Begin by looking around your house. You may notice the most obvious signs of excessive humidity in your home: wet stains on walls and ceilings; rotting and weak wood, mold, and fungal growth; condensation on windows; peeling wallpaper; blistering paint; and a general musty, stuffy feeling. 

What is a dehumidifier? 

A dehumidifier works in an equivalent way to a vacuum cleaner. How can the moisture be removed? A dehumidifier works more like a heating ventilating unit, which is sometimes called an HVAC or air-con, and which itself functions a little like a refrigerator. Are you confused by all the appliances? Let us look at a dehumidifier to see what all the parts do. 

From where does the water originate? 

Water is always present in the air, both inside and outside of the home. The home’s water content varies depending on how you live your day, such as washing dishes, bathing, and making tea. The amount of water inside your home will increase if you have water containers, such as fish tanks or other water vessels. 

What is the ideal humidity level in my home? 

Relative humidity of at least 50% is considered comfortable for your home. This will protect your belongings and prevent mold growth. It will also control dust mite populations. It is not necessary to lower humidity below 45-50%. 

How much water is a dehumidifier capable of removing? 

Three factors are key to the answer. The dehumidifier’s power, the room temperature, and the relative humidity in the air are all crucial factors. A 15-liter dehumidifier will not remove 15 liters of water in one 24-hour period. The dehumidifier should be turned off when relative humidity is at the desired level. This will ensure that the water in the bucket does not drop further. 

Where can I put my dehumidifier in the best location? 

A dehumidifier should be invisible and silent in an ideal world. It is best to be invisible and out of reach. The first option is not possible and the second, although it can be done in certain cases, will cost more and take more effort.
