Some portable dehumidifiers can be configured so that they drain continuously, but care should be taken to ensure that the drainage is not impeded. Other portable dehumidifiers do not drain continuously. These require manually emptying the water bucket when it is full, or the machine automatically shuts off.
What is the concentration of water vapor present in the air?
Humidity is the concentration of water vapor present in the air. Relative humidity – what you hear the weather-person report on – measures the amount of water in the air in relation to the maximum amount of water vapor (moisture). The higher the temperature, the more water vapor the air can hold.
How does temperature affect humidity?
High temperatures enhance humidity's ability to thwart temperature regulation, because warm air can hold more moisture than cool air can. According to the NOAA National Centers for Environmental Information, a 1-degree Fahrenheit (0.55-degree Celsius) rise in temperature equals as much as a 4% increase in atmospheric water vapor.
Why is water vapor lighter than dry air?
The water vapor molecules that displace some of dry air's nitrogen and oxygen are actually less dense, meaning that moist air is actually lighter than dry air; however, because water vapor ousts small amounts of these gases, there's less oxygen in humid air to breathe in.
Does humidity help sweat?
Humidity, however, prevents sweat from evaporating as readily , because the surrounding air already has a high moisture content and can't absorb much more. And the less that moisture evaporates from our skin, the more uncomfortably warm we feel.
What is Humidity?

How to tell if humidity is high?
There are a few ways to deduce if humidity levels are high or low without a specialized instrument: 1 Thermal discomfort. If you feel too hot when the temperature does not warrant it, humidity levels might be too high. In the same vein, if your skin, eyes, or nasal passages get dry and crack, humidity levels might be too low. 2 Condensation. It can be a sign of high humidity. Condensation may form when warm humid air contacts a cold surface. 3 Mold. Dampness in the air can supply enough moisture for mold growth. Also fungi and dust mites. 4 Static electricity. If you notice that your clothes cling or that dust particles stick to electrically-charged surfaces, it may be a consequence of low humidity levels.
How does humidity affect heat loss?
High relative humidity reduces people’s ability to lose heat through perspiration and evaporation. In other words, the human body uses perspiration as a way to self-regulate its temperature. If the air is damp, it takes longer for perspiration to evaporate.

Why does humidity fall?
For example, when outdoor humidity reaches 100%, the air cannot hold any more moisture and it starts to rain. In warmer temperatures , the atmosphere can hold more water vapor so, typically, turning up the heating in a room will cause relative humidity to fall. However, there are many different factors that cause these values to vary.
How to keep your house from getting condensation?
Try to maintain a relatively constant temperature, even if it means turning down the thermostat a little, but keeping the heating on for longer.

What does humidity percentage mean?
What It Means. The humidity percentage is based on a 100% scale. You will often read about humidity as it pertains to the weather. However, based upon the temperature indoors and various other factors, it will also describe the environment indoors.
What does it mean when the humidity is 100%?
If there is a reading of 100%, it means that the air is 100% saturated with water vapor. It is incapable of holding any more water vapor. To explain it even further, if the air is at 100% humidity, it is not going to allow for sweat to evaporate into the air.
Why does humidity feel cooler?
On the same note, when relative humidity is lower, we can actually feel cooler than what the temperature really is, because the sweat evaporates, thus providing a cooling effect.
How does humidity affect humans?
Within various industries, the level of humidity is critical as well. It can impact the amount of dust and other airborne molecules within the air. It can also impact whether there is any kind of puddling or pooling of water on various surfaces.
What does it mean when the air is 100% saturated?
Essentially, the hotter the air is, the more water the air can contain. Relative humidity becomes the ratio of highest absolute humidity against the current absolute humidity, which is dependent on current air temperature. If there is a reading of 100%, it means that the air is 100% saturated with water vapor.
