Reduce the Indoor Humidity: 11 Simple Ways to Follow!

When you have decided to keep your house’s interiors comfortable and cool during the summers, the pointers mentioned in this section can help you do that:

1. Rehome the Indoor Plants

Every homeowner likes to have indoor plants since they not only improve the home’s appearance but will also decrease moisture levels. Plants can easily emit moisture into the air inside. This contributes to home humidity. You can place the houseplants on the porch for a long weekend.

2. Opt for a Dehumidifier

Another method to lower the humidity in house is by employing a dehumidifier. This can help stop the moisture present in the air and will make the indoors cooler. You should get a dehumidifier, which is incorporated into the standalone devices or HVAC system, which will help lower the humidity for the entire house.

If the humidity inside the residence increases greatly and you don’t have a dehumidifier, you can also choose the chemical option. There are many substances like cat litter, rock salt, etc, which can eliminate the moisture of the indoor air.

3. Dry All Your Clothes Outside

The majority of homeowners place all their clothes in the dryer. During the winter, people utilize the indoor dryer racks to dry off all their clothes. However, during the summers, drying all the damp clothes inside the house will increase the indoor humidity.

The best option here is to dry all your clothes outdoors on the clothesline or drying rack. But before doing so, you should check the neighbourhoods. There might be some laws or restrictions. That way, you will not experience any unwanted legal problems.

4. Repair All the Leaking Pipes

You surely don’t wish to add more moisture when you’re planning to lower the humidity in house. This is what exactly all the leaking faucets and pipes do. You must repair/replace all the leaks that you find across your residence.

Wrap up the leaking pipes with insulators, which will prevent the condensation from forming. Some of the best ways you can spot leaks are when you have irregular water bills, wet spots, and stained drywall.

5. Improve the Home’s Ventilation

When it comes to ventilating the house, you should do so by turning on the exhaust fan. Doing so will get rid of the humid air present inside the house and reduce the indoor humidity levels.

Besides that, if you have an AC unit and a furnace, make sure to clean their filters periodically so that the airflow keeps running at an excellent pace. However, if the humidity’s source is from the rain in the summer, letting in outdoor air is not a great idea.

6. Improve the Ventilation in the Crawlspace

Crawlspaces can instantly collect moisture when it’s not ventilated correctly. According to the style of the house, the cellar might be totally enclosed, which assists in securing the moisture inside.

You can also put in a wall vent to increase ventilation in the crawlspace and stop moisture from getting stuck there. Furthermore, adding a ventilation system can lower the humidity in home during the summertime.

7. Prevent the Seepage

Keeping the gutters in excellent condition will redirect the water away from the residential property. However, if there is a seepage, it might occur because of landscaping problems or because the foundation has cracked.

All homeowners need to do is prevent seepage from occurring to lessen the humidity levels inside. The best way to get this done is by slanting the landscaping away from your house, opting for outdoor waterproofing and patching up all cracks on the foundation.

8. Cover Up the Pots When You Cook

The indoor humidity can increase because of a diverse range of sources, and one of them is “cooking.” The boiling water in the pots and the moisture that gets released into the indoor air when you fry food items can greatly increase indoor moisture levels.

However, you can lessen the humidity level by covering up the cooking pans and pots. By doing so, it will prevent moisture from getting out and also enable you to cook quickly.

9. Utilize Charcoal Briquettes

These days, people don’t use the charcoal briquettes for barbecues. They are also used as a dehumidification tool. This is not a joke! It does work! To use the charcoal briquettes, you have to place a few of them in a “container” – a can or a small basket will surely work.

The charcoal is pretty absorbent, and it will instantly suck in the moisture from the indoor air. To keep using charcoal, make sure to replace it every 2 months to 3 months.

10. Keep All the Surfaces Completely Dry

It’s crucial to wipe the surfaces of your washroom and kitchen after using it to stop the evaporating water from mixing with the indoor air. Wet towels and floor mats should be properly dried and washed to prevent them from becoming the actual source of indoor humidity levels.

11. Fill Up a Bowl with Baking Soda

In an empty bowl, add baking soda to it. After that, place the bowl in a spot where you’d like to minimize the moisture level. Baking soda will easily absorb the humidity present in the indoor air. You will know that the humidity levels decrease when baking soda becomes harder. When it becomes way too hard, remove it and replace it with new baking soda.
