How to Get Rid of Humidity from a Room by Using Salt

Excess humidity in our homes must be tackled as it can lead to unsightly wet spots on the walls and can lead to the appearance of mold that can have adverse effect on our health, especially for asthmatics or people with allergies. The saturation level of moisture in the air of our homes depends largely on the climate of the area in which we live. This often exceeds the optimum levels for our health, especially during the summer when the humidity increases. There are electric dehumidifiers you can buy from a store, but they can often be costly and you may not need something so powerful to provide a humidity solution. Keep reading oneHOWTO to see how to get rid of humidity from a room using salt and see if it works first.

Humidity in your home might just be the cause of many household problems without you even realizing it. It might be more noticeable in the summer, but it is a problem which can persist all year round. To know if you need to get rid of humidity in a room or home, look out for these signs:

  • you feel hotter: of course in warmer weather your body will feel hotter, but if the humidity is too high you may find it almost impossible to cool down. When you sleep you will feel sheets sticking to you and after a shower you may sweat even more, finding it difficult to get dry. The high humidity of the room causes your pores to clog which, in turn, makes it difficult to cool down, something not simply related to temperature.
  • increased mold: high humidity in a room will lead to a combination of heat and moisture which is a breeding ground for bacteria. This causes mold to appear on walls, fabrics and almost anything porous, destroying clothes and leading to potential health difficulties as breathing in this mold due to high humidity can be dangerous.
  • physical symptoms: the mold caused by high humidity in your room is usually accompanied by a fusty smell, something which can be hard to eradicate or even cover up. The bad smell caused by high humidity in a room might also transfer to yourself. If you find deodorant isn't quite covering up your natural musk, it could be a result of high humidity in your room clogging up pores.
  • changes in your room: it may not be just you or the room which smells bad, but pets also might become smellier than they otherwise might do naturally. High humidity in your room can cause wood to swell, something you might notice if your door sticks in the jamb. The water in the air can cause oxidization of metal objects, forming rust and making some things useless.
  • pools of water appear: if you see pools of water underneath your windows or thick droplets on the panes, this is usually due to high humidity in your room. You might find it difficult to cook as you will sweat more. If you have high humidity in your room you may even sweat just from eating hot food.

High humidity in your room can be a problem, but so can low humidity. It can make the air drier, cause your skin to lose moisture (resulting in cracked dry skin) and can increase the risk of contracting viruses or infections. The ideal humidity in your room should be 35-45%, although a little over or under this shouldn't cause too many problems.

How to Get Rid of Humidity from a Room by Using Salt - Step 1

If you are experiencing some or all of the above problems, then you might want to get rid of humidity in your room. The most basic way to get rid of humidity is to get a flat container with an open top and fill it with a kilogram of coarse salt. Set it in the room with high humidity and you will soon see that it has absorbed a lot of the excess moisture in the air. A wider container is better as it will allow for more exposure, but you may need to add more salt also.

After 2 days you will see that the salt will have already absorbed much of the excess moisture caused by high humidity in the room. This is because salt is one of the most absorbent natural products available, helping to combat moisture in the walls or to prevent mildew staining on clothing. This is the most basic method of making a homemade dehumidifier, but you can read this article on how to make a dehumidifier with rock salt to see a slightly more advanced method.


When the salt has blackened or is too wet it means it has already reached its maximum level of saturation. At this moment, you must change the salt and add new salt so it can continue to absorb more moisture from the room. If, for any reason, you don't want to use salt, there are other materials you can use. Cat litter, good for absorbing up the moisture your cat emits, is ver absorbent and can be used in the same way. However, it won't work well in large space so you might want to use it in smaller ones. Charcoal might also be useful, although perhaps not quite as effective. There are chemical ones you can find which often come in a small dehumidifier. While these essentially use the same process of absorbing moisture from the high humidity in your room, they are often too small and ineffective.

It's important to also know how you can prevent humidity at home, there are some simple tricks you can use in your room so you don't have mold stains or health concerns. If you have high humidity in your room, it's important to air it frequently so the air inside is renewed. This is as simple as opening a window to let air circulate.

  • If simply opening the window isn't enough, using extractors or vents when cooking or taking a shower will help to get rid of the saturated air caused by high humidity. Taking a colder shower will also help. It's one reason why we eat cool salads in summer, being in a hot kitchen with high humidity can be intolerable.
  • Using fans to move air around will also help, but nothing beats an air conditioner. Buying an air conditioner or electric dehumidifier should be done if the homemade dehumidifier has proved unsuccessful.
  • Dry your clothes outside or on a terrace as the moisture from the clothes will otherwise enter the air of your living space.
  • Check materials or objects which might be increasing the humidity. Carpets can hold a lot of moisture, so if you have high humidity in your room, you may want to consider laminate (untreated wood can also absorb moisture) or linoleum. Plants also release water vapor, contributing to the humidity. Although they are visually lovely, you may want to replace them at some point to help get rid of humidity in your room.
  • Exposed pipes or leaky pipes are also big causes of humidity, so check to see if they are secure and whether or not they need insulated. Check the roof, window seals and anywhere else which might be causing moisture to come into your room. This may require some professional advice.

To hide the humidity stains, you may have thought of painting your home walls. However, you must take into account different aspects of damp-proofing. For example, the paint you use for the wall must be anti-humidity sealant paint which will help protect you from moisture. However, be careful if you already have mold in the wall as just painting over with sealant paint might be good for the humidity in your room, but it may also cause rising damp or rotting. You will also have to clean the stain before painting or the result will be horrible. At oneHOWTO we can give you some tips on how to paint a damp wall.

Good suggestion.

Thanks for the advice. A/c is out of reach of common man. Moreover, a/c pollutes air which further resulted into global warming. Consumption of electricity by an a/c of one ton is equal to electricity consumes by nine fans. This being the fact, the use of salt to get rid of humidity is not only affordable but it is a contribution to the programme of minimization of global warming.

Mould* and a useful tip, you can also put the salt in oranges that have been cut in half and scooped out, it releases a scent along with taking away the moisture in the air.
