How to Naturally Dehumidify a Room

Not everyone has a dehumidifier at their disposal — and not everyone wishes to invest in one. Fortunately, there are numerous simple and cost-effective techniques to reduce humidity in your home. Let’s break each of these methods down.

Ventilating Your Rooms

Sometimes, the simplest methods are the most effective, and that’s certainly true for combating excessive humidity in the home. Basic ventilation — simply opening your windows and doors — can aid in reducing moisture levels, particularly in rooms where we produce a lot of moisture, like the kitchen, bathroom, or laundry area.

Fresh and dryer air from outside can replace the humid air inside your room, creating a healthier environment. When you cook or shower, use an exhaust fan to draw out the damp air and bring in drier air.

However, remember that this technique is useful only when the outside air is less humid than the wet air inside.

Using Rock Salt and Baking Soda

Rock salt dehumidifier is an efficient desiccant that pulls moisture out of the air. You’ll need two buckets of the same size to use this method. Drill several holes in the bottom and sides of one bucket, fill it with rock salt, and then place it into the undrilled bucket. Place this setup in the most humid area of your room and watch as the rock salt absorbs the moisture released into the bottom bucket.

Baking soda is also a natural dehumidifier. Simply put an open box of baking soda in small spaces like cupboards, wardrobes, or bathrooms to absorb the moisture. Don’t forget to replace the box every two months to keep the desiccant effect going.

Enlisting the Help of Dehumidifying Plants

Another natural solution to reduce humidity is dehumidifying plants. These indoor plants naturally absorb moisture from the air through a process called transpiration.

English Ivy, Peace Lily, Boston ferns, Reed Palm, and Tillandsia are a few examples that can effectively decrease relative humidity levels. They also purify the air and provide a pleasant aesthetic to your interior decor.

Other Natural Absorbents

Some everyday household items can act as natural absorbents to help you dehumidify your home or room. Charcoal briquettes are used to absorb moisture, like rock salt. Place a few briquettes in a bowl, or coffee can put the container in an area where you want to reduce moisture and let it work its magic.

Similarly, containers filled with cat litter or white rice also effectively absorb excess moisture in the air. These items can be placed in closets, cabinets, laundry rooms, or any room where you notice increased humidity. Just make sure to replace them regularly for a long-lasting effect of absorbing moisture.

How Ventilation Benefits Your Room

Well beyond mere dehumidification, mastering efficient ventilation can magnify the freshness and wholesomeness of your living space, mitigating the accumulation of indoor pollutants, odors, and airborne contaminants.

Techniques like cross-ventilation can moderate temperatures, distribute air evenly, and supplement your efforts on how to dehumidify a room without a dehumidifier. By skilfully wielding these natural processes, you defend your home against moisture’s destructive consequences, fostering a healthier, cozier, and more agreeable atmosphere.


Commercial Dehumidification Solutions

While natural methods can indeed help to reduce the relative humidity in your home, sometimes they may not be enough to control moisture, particularly in parts of the world with a high-humidity environment.

In such cases, you may have to consider commercial dehumidification solutions. Let’s take a closer look at three of the most effective ways to control humidity in your home: using a dehumidifier, incorporating an air conditioner, and using a ceiling fan.

Using a Dehumidifier

A dehumidifier helps pull moisture out of the room

Dehumidifiers are specially designed to extract moisture from the air. These electric appliances work in one of two ways.

  • Refrigerant-based dehumidifiers draw in air, cool it down, and collect condensation, which is removed into a water collection tank.
  • Desiccant dehumidifiers, on the other hand, use a moisture-absorbing material to dry the air, then reheat it before blowing it back into the room.

When choosing a dehumidifier, consider the size of your room and the humidity level. Keep in mind that dehumidifiers vary greatly in price, and higher-capacity models will typically cost more. For more information, please review our blog post about the best dehumidifiers in the Philippines.

Incorporating an Air Conditioner

Air conditioners do more than just cool down a room – they also act as dehumidifiers. Cooling the air inevitably reduces its moisture content, thus lowering humidity and helping to control the relative humidity. That is particularly true for regions with hot and humid climates since air conditioners can monitor both temperature and relative humidity levels.

However, like dehumidifiers, selecting an air conditioner suitable for your room’s size and conditions is important. An AC with a good energy efficiency rating will also save you money in the long run. For guidance on selecting an air conditioner, refer to our blog post about the best aircon in the Philippines reviews.

Using Ceiling Fans

While ceiling fans alone do not directly remove moisture, they can be a valuable addition to commercial dehumidification solutions.

By circulating and distributing air evenly across the space, ceiling fans can help increase airflow and improve the efficiency of dehumidifiers and air conditioning systems. This enhanced circulation promotes faster moisture evaporation on various surfaces, making the room feel cooler and more comfortable.

Moreover, using ceiling fans in conjunction with ventilation systems can promote better airflow within a room, facilitating better moisture regulation in the long run. Combining ceiling fans with existing commercial dehumidification methods can optimize space for maximum comfort and humidity control.


Maintaining a Dehumidified Room

Achieving a good level of dehumidification is only half the battle. Implementing a maintenance routine to sustain a comfortable and healthy environment in your room would be best. Let’s look closely at some ongoing tips, strategies, and preventive practices.

Ongoing Tips and Strategies

Installing vent fans helps dehumidify a room
  1. Regular Ventilation: Remember to keep the airflow going through your home or workplace. Regular ventilation is key in maintaining a dry environment where mold and mildew cannot thrive. Open windows daily, especially after showers or while cooking.
  2. Use of Vent Fans and Exhausts: A proper ventilation system uses fans and exhausts strategically. They help circulate air within a room and expel humid air outside. Bathrooms and kitchens should be equipped with exhaust fans when too much moisture is in the air.
  3. Regular replacement or emptying of your dehumidifiers: Regular maintenance is required for those using electric dehumidifiers or dehumidifying materials such as rock salt and charcoal. For electric dehumidifiers, empty the water collection tank regularly. For other dehumidifying materials, replace them periodically to ensure their effectiveness.

Preventive Practices

  1. Fix leaks promptly: One of the easiest ways to prevent excess humidity in a room is to manage the source. Immediate repair of leaks, whether from pipes, roofs, or windows, is crucial in preventing moisture buildup.
  2. Increase Plant Population: Plants can play a dual role in beautifying your space and regulating indoor humidity. Opt for plants that act as natural dehumidifiers, such as English Ivy, Boston Ferns, and Peace Lilies.
  3. Mind your Indoor Temperature: Since warm air holds more moisture, consider using air conditioning ceiling fans or any other energy-efficient fans during hotter months to keep room temperatures cool and control excess moisture.
  4. Strategic Use of Blinds and Curtains: By closing blinds and curtains on sunny days, you can reduce the amount of heat entering a room, thereby controlling the humidity levels.

Maintaining a dehumidified room can become an effortless routine through these tips and practices. By making just a few small changes to your habits and the setup of your room, you can enjoy improved indoor air quality, better health, and a more comfortable living or working environment.


Understanding Dehumidification
