8 Benefits of Dehumidifiers in the Home

The benefits of dehumidifiers can be vast! While they are easy to overlook, dehumidifiers should be a tool that you use to regulate the environment of your home.

Dehumidifiers draw moisture out of the air to reduce the humidity within the home and eliminate musty odours and replace the air with drier, fresher air. These may seem like simple devices, but they can significantly impact and benefit your home.

this article will provide you with 8 benefits of adding dehumidifiers to your home.

1. Reduces Mold and Mildew

Mould and Mildew can grow and become trapped under and within the carpet as well as behind wallpaper. These moulds and mildews are growing funguses that reproduce and spread within the piling of carpets and between the wallpaper and the wall. Shaggier carpets are especially prone to Mildew.

Mildew is recognizable by its musty and damp odour, which is a result of the trapped humidity. Mildew can be removed by eliminating the fungus that is reproducing, remove its source of enrichment (food), or remove it from its water source (humidity).

Mould and Mildew thrive in climates with over 60 percent humidity. Therefore, an indoor environment should be kept below 60% humidity.

Dehumidifiers are practical and simple solutions to control indoor humidity and reduce the likelihood of mould and Mildew forming and spreading.

2. Reduces the Amount of Dust (Mites) in the Home

Dust mites are tiny organisms that primarily feed on dead skin cells. They are related to spiders. While they do not directly harm or feed on humans, they can cause serious irritation to family members in the home.

Dust mites are a major source of allergens in the home, and they can incite asthma.

Not surprisingly, dust mites prefer warm and damp climates. They like to house themselves in bedding, upholstered furniture, mattresses, rugs, carpets, curtains, and stuffed toys of children.

An easy way to reduce the number and activity of dust mites in the home is to make the climate less hospitable for them. Reducing the humidity makes the humidity uncomfortable for dust mites. Dust mites do not like climates with humidity between 30 and 50 percent.

Set your dehumidifier near your bed, which houses the most dust mites, to reduce the amount of dust mite activity in your bedroom. To reduce the dust mites in other rooms, you will need to get a stand-alone dehumidifier for each room.

3. Less Skin and Lung Irritation (Asthma)

Irritants within your home’s environment can cause the skin to break out or increase the effects of eczema, rashes, and itching. Some skin rashes and irritation can be caused by dust mites, dander, or Mildew that is in the air.

Reducing the humidity in your home can reduce dust mite colonies, dander, and other irritants that collecting on furniture or under fabrics.

The same skin irritants, which can float in the air, can cause irritation to the lungs. Irritants in the air can cause an increase in cough, feelings of a closing throat, and tightening in the chest. Breathing problems can lead to more serious issues, such as heart palpitations, feelings of weakness and exhaustion, difficulty swallowing, chest pains, fevers, and changes in the voice that are permanent.

Dehumidifiers in the home can help remove irritants or reduce the activity of irritants in the air that cause lung trouble. It can also keep the air at a more comfortable temperature while regulating the moisture of the air. Therefore, the air does not feel heavy on the lungs.

4. Sleep Better

Humidity and moisture significantly impact your ability to sleep comfortably. Higher levels of humidity do not allow for the necessary evaporation of water and sweat on the body as you sleep. This makes you uncomfortable in your bed, and it makes you feel significantly hotter.

It is recommended that your bedding is a breathable fabric like cotton or silk because of increased airflow that allows your body to cool itself as you sleep. The same can be said for the environment of the air in which you sleep. You want the air to be less humid so that the sweat your body produces can evaporate quickly.

Keeping the air below 60 percent humidity allows for a comfortable rest that does not feel burdened by hot or heavy air. Moreover, the dehumidifier will control the dust must and allergens that may irritate a sleeper with asthma or allergies.

Keeping a dehumidifier in the bedroom can help with better and more restful sleep.

5. Increases the Life of Your Belongings

Aside from mould and Mildew, humidity in the home can produce rust spots and spoil grains (like bread) quickly. Reducing humidity in the home can increase the lifespan of several of your belongings, as well as the home itself.

Closets can become particularly humid, as moisture can collect in the walls, floors, carpets, and crevices. Linens and clothes that are placed in closets are at risk of forming mould or Mildew. This growth can be particularly irritating and harmful to the body when those linens are placed on a bed and the mould inhaled.

Closets and furniture next to bathrooms are at a high risk of experiencing mould or Mildew. Having a dehumidifier nearby can reduce the effects of increased humidity caused by a shower.

The constant flux and increase in humidity caused by showers can cause rust stains either in the shower or bathtub as well as the walls or fixtures around the shower. Dehumidifiers can help regulate moisture, which will reduce the risk of metals like tools, hinges, bathtubs, sinks, and toilets from experiencing rust damage.

As evident from the previous discussion of Mildew, dehumidifiers can reduce the buildup of Mildew in carpets and wallpaper. The avoidance of excess moisture will increase the longevity of your carpet or wallpaper and avoid the risk of continually replacing them due to excess moisture.

6. Reduces your Energy Bills

While it may seem counterintuitive, running a dehumidifier in the home can reduce some of your energy bills. When the dehumidifier runs, the air feels slightly cooler. More moisture causes the air to feel hotter. Drier air will feel cooler to the body.

Utility bills

This means that you will be less likely to turn up the air conditioning to a higher setting, reducing your bill for air conditioning. Moreover, the reduction of its use causes an increased lifespan for your air conditioning system.

Some may worry that the cost of running the dehumidifier will outweigh the cost saved in air conditioning. This is unlikely, as the average amount of volts needed to run a dehumidifier is significantly less than the amount of energy needed to run a compressor in an air conditioning system.

7. A Better-Smelling Home

Mould and Mildew, as well as their spores, can find their way into several different parts of the home. Mildew loves materials such as wood, leathers, paper, carpeting, and Mildew loves baseboards, walls, and sinks. After finding places to hide, Mildew and mould can cause bad odours in the air and around your home.

Good smelling home

A dehumidifier can take in the old air and replace it with drier, fresher air. You can even improve the smell of closets, dressers, cabinets by opening the drawers and allowing several days for the moisture to evaporate.

By removing and replacing moist air that carries the smell of Mildew or allergens, a dehumidifier can make your home smell better in a cost-effective and timely manner.

8. Prevents Damage to Expensive Electronics

Electronics are at a particularly specialized risk of damage from humidity. Electronics are sensitive to moisture in the air. While electronics can rust, their internal components can be damaged from moist air.

Moisture can gather in the electronics, and this can cause electronics to malfunction. Reducing moisture, especially in areas of your home where electronics are housed, can save your electronics from damage and extend their lifespan.

Getting a Dehumidifier for Your Home

Dehumidifiers can be expensive, but their benefits far outweigh their cost. Additionally, there are several different kinds of dehumidifiers available on the market. You can easily find one that suits your needs and your financial means.

Your belongings, your home, and your health will certainly benefit from placing a dehumidifier in your home.
