Yes, baking soda can dehumidify a room by absorbing moisture, but it's only effective in small, enclosed spaces like closets, cabinets, or bathrooms, not large rooms, where it acts as a mild, natural dehumidifier and odor neutralizer, turning clumpy as it works, requiring replacement. You simply place bowls of baking soda in the damp area, and replace it when it hardens.
Baking soda is an inexpensive and versatile option that effectively dehumidifies small spaces, like cabinets.
To decrease humidity in a room, you may 1) Use rock salt, 2) Improve air circulation with fans or air conditioning,3) Run a space heater,4) Run a dehumidifier, use exhaust fans, open a window (if the air outside is dry), keep doors closed.
Blot to absorb excess moisture and leave to dry. Sprinkle with baking soda to let it absorb the remaining odours and dampness. Scrub in and leave for another few hours before vacuuming the area.
Use dehumidifiers and air conditioners, especially in hot, humid climates, to reduce moisture in the air, but be sure that the appliances themselves don't become sources of biological pollutants. Raise the temperature of cold surfaces where moisture condenses. Use insulation or storm windows.
Increasing ventilation can draw out excess moisture. Ventilation fans that vent the air and moisture outside of your home help. Install and run ventilation fans in bathrooms and in the kitchen. Opening windows can also help with ventilation.
Symptoms of excess home moisture include window condensation, mildew, mold, peeling paint and excessive dust mites. To control a moisture problem, first identify the source and remove it. If not possible, use ventilation or a dehumidifier.
Ways to Dehumidify Your Home Naturally
The most effective placement for baking soda is on a central shelf or near the source of odors. This allows for maximum air circulation and odor absorption. Avoid placing it in areas where it might be blocked by food items or in tight spaces with limited airflow.
High humidity can cause problems in your home if relative humidity regularly exceeds 60%. When the air contains water vapor above that level, mold and mildew start to grow, while excess moisture can cause rot, damaging your belongings.
Ventilation is Key
Improving airflow in your home is crucial for reducing humidity. Open windows in the early morning or late evening when the air outside is cooler and less humid. Use exhaust fans in your kitchen and bathrooms to expel hot, moist air and help prevent the buildup of humidity.
High humidity in a house can be caused by many things, but the biggest reason is poor ventilation—in other words, air isn't being circulated properly, which causes the air in your house to become stagnant and humid. The other major reason? Too much air exchange with the outside.
Use Baking Soda in Air Vents
Baking soda naturally absorbs odors, just like it does in your refrigerator. Leave it in the duct for several hours or overnight, then remove it. You can repeat this process as needed to help neutralize mild smells.
Baking soda makes our cakes rise, neutralizes fridge odors, softens the laundry, and scrubs out stains. You may have used it to freshen your plumbing, clean your appliances, and bring back the shine on your silver. These and so many more uses make the pantry staple a real jack-of-all-trades around the house.
Limited Effectiveness for Serious Clogs
The chemical reaction between baking soda and vinegar can break up some minor debris, but it won't dislodge or dissolve the heavier blockages caused by grease, hair, soap scum, or mineral buildup.
Mold needs 55% or higher humidity in order to grow. Also, remember that reducing humidity below 30% isn't a good idea, either.

Essential Components for a DIY Dehumidifier
7 Signs Of High Relative Humidity In Your Home
Opening windows promotes more airflow, which enhances ventilation inside the building. This guides in eliminating sticky, humid air and supplanting it with drier external air. Ventilation is essential in regions like kitchens, showers, pantries, and other rooms where dampness is delivered.
High humidity can cause bronchial constriction, which is when the airways narrow. Humidity can make it harder for all of us to breathe, but it can particularly aggravate symptoms in people with respiratory illnesses such as chronic obstructive pulmonary disease (COPD), allergies and asthma.
Take some scrap pieces of foam, or even cardboard, and cut 4 rectangular legs for the dehumidifier to stand on. Cut one of the short ends at a 45 degree angle and hot glue it to the fan as shown in the pictures. Since the heat sink on the bottom will collect water it might start dripping if the air is humid enough.
Open a Box of Baking Soda
Baking soda, while also effective at absorbing odors, can also absorb moisture. If one room is more humid than others, leave an open box of baking soda on a window sill. Rock salt and calcium chloride are also good at wicking up moisture.
