How To Use a Dehumidifier To Dry a Room
Publish time:2018-08-06 丨 View counts:1658

House dehumidifiers is very good useful to our health, and how to use the dehumidifier?

We are a professional supplier of Commercial Grade Dehumidifier in China. Here I recommend some of our most popular products as following:

The ideal relative humidity (RH) level for a room is between 45% – 55% though this may drop down to 40% during the winter months to avoid condensation on windows etc.

If the RH stays at over 65% for a prolonged period of time mould is likely to grow therefore a dehumidifier can help keep the air moisture level down.
Preferably you should use a hygrometer to detect the correct RH level for each room in your home as each room will most likely have a different reading.
During the cooking of food the kitchen should have a higher reading than the living room. Similarly when having a shower the bathroom will show a higher humidity reading than say the dining room.
“A good first step is to invest in a hygrometer to determine, and then monitor, the humidity level throughout your home. Once you identify the areas that would benefit from reduced moisture you can then build your plan to manage your in-home humidity.”
If you don’t have a hygrometer (or don’t want to buy one even though they are not expensive) then you can gauge the relative humidity level as follows:
Humidity Level Over 65%,  Air feels ‘close’ or ‘stuffy’;Skin feels moist & clammy;It gets harder to breathe;There could be a musty odor in room
Humidity Level Under 35%, Skin becomes dry, flaky and/or itchy;Lips become chapped and may crack & bleed;Paint may start peeling of walls & furniture;Wooden instruments and furniture may warp.
The above humidity levels lie outside of our comfort levels so a dehumidifier should be used well before symptoms of very high humidity levels occur.
Take The Ice Test,In order to check if the air is too dry you can take the ‘Ice Test’.
Simply fill a glass with water and place three ice cubes into the water. Stir and leave to stand for 3 minutes. If no water droplets have formed on the outside of the glass after this time then the air is too dry.
How To Use A Dehumidifier 
First of all there are two main types of full size dehumidifier.
They are:
  • Compressor dehumidifiers
  • Desiccant Dehumidifiers
Very basically a rough usage guide would be to use a compressor dehumidifier if the dehumidifier will be mostly used in temperatures above 20°C (such as a very warm house or during the summer).
You should use a desiccant dehumidifier if the dehumidifier will be used mostly in temperatures of below 20°C (if using the dehumidifier in areas of the house where the heating is turned off in winter for example).
Compressor dehumidifiers become more efficient in extraction as the temperature rises.
Desiccant dehumidifiers are more stable in efficiency than compressor units but become slightly more efficient as the temperature falls. Desiccant units can also operate at lower temperatures than compressor units which is worth bearing in mind if you are looking for a garage or shed dehumidifier.

Stand a Compressor Dehumidifier Before Use

Upon unpacking a compressor dehumidifier you should leave the unit to stand without operating it for at least an hour.
Different dehumidifier manuals give different time lengths to stand a dehumidifier
During transportation the oil in the compressor may have leaked into the system. If you let the dehumidifier (or fridge etc) stand the oil will settle back allowing the dehumidifier to function properly.
If the dehumidifier is used too soon then the system could get blocked which results in a system breakdown. It is likely that your warranty won’t provide cover if this happens.
Using a Desiccant Dehumidifier For The First Time
Unlike compressor dehumidifiers desiccant models lack a compressor component.
The lack of compressor makes desiccant dehumidifiers generally lighter and quieter than compressor models.
Also due to lack of compressor parts desiccant dehumidifiers can be used as soon as they are unpacked.
Smell From Desiccant Dehumidifier
When using a desiccant dehumidifier for the first time, and for a few times after, you may notice a slight burning smell coming from the dehumidifier.
This smell is perfectly normal as the Zeolite desiccant material absorbs smells from items such as cigarettes, hair sprays and cosmetics etc. When the desiccant material is heated these smells are then discharged back into the room.
The smell won’t last long and is not a cause for concern.
A common question is where to position a dehumidifier.
First of all ensure that the dehumidifier is placed on a solid, level flooring in an upright position.
Keep the dehumidifier away from walls, furniture and other objects that may impede airflow. Do not place any clothes etc on top of the dehumidifier.
Placing the Dehumidifier in a Room
When placing the dehumidifier in a room ensure that the appliance is placed on the floor. Placing the dehumidifier on top of tables or lockers can increase the chance of accidents.
Place the unit near a socket so that it can be plugged in without the aid of an extension lead.
Personally I’ve had the best result with placing the dehumidifier near the windows as a quick blast with the unit in Laundry Mode clears heavy condensation on the windows in around 5 – 10 minutes.
Placement is an individual decision as different problems require different solutions. For example you may have a damp wall which you may want to place the dehumidifier next to or you may want to clear the windows of condensation as mentioned above.
For single room use we strongly recommend this mini dehumidifier.
Placing the Dehumidifier in a Hall
The best place for a full size dehumidifier is in the hall or on a landing.
Ensure that all the doors leading to different rooms are open so that all the air in the house will migrate to the dehumidifier naturally.
Again keep the unit, and especially the air filter, free of any obstructions.
Using a Dehumidifier to Dry Laundry
When using a dehumidifier to dry laundry you should use the smallest room in the house.
Hang the clothes on a clothes horse or similar contraption but do not place any clothes on top of the dehumidifier. Keep the clothes away from the dehumidifier so that if they do fall down from the clothes horse that they won’t fall on top of the dehumidifier.
Keep the doors and windows closed and run the dehumidifier in Laundry Mode for several hours.
You will find that when dehumidifiers operate in Laundry Mode they generate a lot of heat which helps dry clothes quicker.
