Calcium chloride can soak up water more than twice its weight and is another potent moisture-absorbing material.

It’s a frequent ingredient in moisture-absorbing bags, which are great for damp areas like closets and basements. 


Charcoal briquettes are an environmentally beneficial choice for dehumidification.

Because of their porous composition, they are effective natural air purifiers that remove hazardous pollutants and eliminate disagreeable aromas.

Fact: Bamboo charcoal's remarkable absorption capacity and eco-friendliness have contributed to its rise in popularity as a sustainable alternative. 

Utilize Plants to Reduce Humidity in a Room

Plants are a beautiful and natural way to lower the humidity in a room.

The removal of pollutants and the release of oxygen by these plants makes for healthier air and makes it easier to maintain a pleasant relative humidity

Bringing elements of nature inside can also have a positive effect on your mental health and stress levels.

Here are some of the plants you can consider keeping in your room: 

The Peace Lily

Spathiphyllum, more often known as the peace lily, is an intriguing option due to its ability to flourish in low light.

It is well-documented that it may eliminate formaldehyde and benzene, two typical contaminants found in residential and commercial buildings respectively. 

The Spider Plant

The spider plant, or Chlorophytum comosum, can survive with very little attention and thrive in a variety of environments.

It can effectively reduce formaldehyde and xylene, two common VOCs, from the air, creating a healthier indoor atmosphere. 

Optimize Heating and Cooling to Reduce Humidity

Improving the efficiency of HVAC systems is essential for controlling humidity and keeping buildings at a suitable temperature.

Proper maintenance of these systems is vital because it also leads to other benefits, such as:

  • Better humidity control
  • Energy savings
  • System longevity

Air conditioners serve a dual purpose in regulating both temperature and humidity since they remove moisture from the air as they cool it.

If one is available, using the dehumidifier setting will help expedite the drying process. 

An Important Consideration

Never overlook the importance of routinely replacing filters.

Filters that aren’t clean can hinder the performance of the system, trap allergies and mold, and even lower the quality of the air within the house.

Fact: Filter replacement every three to four months can reduce energy consumption and save up to 15 percent of energy. 

Avoid Over-Watering Plants to Lower Humidity

If you don’t pay attention to how much water your plants actually require, you could end up accidentally contributing to higher-than-desired humidity levels in your room.

Avoiding over-watering helps in many ways.

For instance, it helps:

  • Keep the house at a reasonable temperature
  • Promote robust plant growth
  • Stop the development of mold, mildew, and root rot

Here, it is important to learn about how plant species, pot size, soil type, and interior environment may all affect a plant’s water needs.

Learning how often and how much to water your plants will help you get optimal results. 

An Important Consideration

Investing in moisture meters, which detect the soil’s moisture level can help you avoid over-watering.

Succulents and cacti, which are particularly sensitive to water conditions, benefit greatly from their use. 

Additional Ways to Reduce Humidity in a Room Naturally?

Besides trying some basic ways, you can always use many other tricks to significantly lower humidity levels in your room and home as a whole. 

Make Use of Fans

Whether from the ceiling or a portable fan, improved air circulation using a fan is key to lowering humidity levels.

A fan can draw hot, muggy air outside while drawing in fresh air.

Mold and mildew are less likely to grow because of the constant airflow, which helps prevent moisture from accumulating on surfaces.

Fact: It is always a good idea to position fans near open windows to improve their efficiency.  

Dry Clothes Outside

Drying clothing indoors on a line causes water to evaporate and humidify the air.

Hang your laundry outside or on a well-ventilated surface like a porch or covered balcony to avoid this. 

Stop Boiling Water Often

Prevent condensation by using lids and reducing the amount of time spent boiling water.

Use lids on pots and pans to trap steam and reduce moisture release during cooking. 

Correct Pipe Leaks
