How Does a Wardrobe/ Closet Dehumidifier Work?

Most wardrobe/ closet dehumidifiers will use adsorbent materials like silica gel or charcoal to extract moisture in the air. The reason for silica gel popularity is because of convenience, compactness, and reusability. A renewable closet dehumidifier does not require a power outlet to drain the moisture in the air. You will only need to charge the dehumidifier to release the absorbed moisture out through heat. Once the dehumidifier is all charged up, just place it inside a closet and leave it be for 20-30 days. If the humidity problem is beyond what a silica gel can like take in, consider getting an electrical dehumidifier for a better moisture removal performance.

Do I Need a Dehumidifier In My Closet?

You will need a mini dehumidifier if the closet feels damp or there are mold patches spotted. A dehumidifier can maintain the dampness level in the closet under 50% to discourage the growth of mold. But not all closets need a dehumidifier. A hygrometer would come in handy to check the humidity level in the closet or look out for the following signs:

  • There is a scent of mustiness rushing out when you open the closets.
  • There are cracked and water stains in the closet.
  • Closet is located in high humidity places with poor ventilation like the basement, bathroom, laundry room, or garage.
  • Items in the closet are damaged by moisture, mold, or mildew. For example leathery goods, clothes, musical instruments, documents, sentimental/ vintage items, watches, or garage tools
  • Foods are stored in the kitchen closet.
  • The closet has moisture and mold problems in the past.

Should I Go With A Large Dehumidifier Instead?

A large dehumidifier is downright more effective than a mini dehumidifier as it can absorb more moisture per day. It can also manage the humidity level in the entire room rather than just restricted to the closet. But the issue is it cannot offer the same versatility as a renewable dehumidifier. First, you will need to find an electrical outlet to power the large dehumidifier. Second, it is also bulky that will not fit inside a closet or drawer. Third, a large dehumidifier is very noisy and you will need to empty the collected water in the bucket regularly. Lastly, expect to pay 10-20 times more than a mini dehumidifier.

Where To Place a Dehumidifier In The Closet

The ideal position for the dehumidifier would be as centrally as possible to the source of the dampness. That way, the entire wardrobe will get an equal amount of moisture removal from the tiny device. If your moisture problem is in the drawers or bags, place the dehumidifiers inside and keep it closed. For walk in wardrobe, place the dehumidifier at the center of the room.

Different Types of Dehumidifiers for Closet

Not every type of dehumidifier is suitable for closet or wardrobe use. Some are too costly, bulky, noisy, and plain inconvenient. Let's look at the few types of dehumidifiers in the market that can reduce excessive humidity and prevent mold/ mildew.

  • Rechargeable/ renewable dehumidifiers - Also known as a wireless, cordless, mini dehumidifier. It is compact, lightweight, eco-friendly where you can recharge and reuse the dehumidifier for many years. Some models even come with a built-in hook where you can hang it in the closet. Powered by silica gel that will slowly but steadily absorb moisture up to 30 days. Since it is a non-electrical dehumidifier, no battery or power outlet is needed. The best choice for the closet due to the quietness and versatility.
  • Battery-powered dehumidifiers - Similar to renewable in terms of size and functionality. A battery operated dehumidifier is also suitable for closet, car, or bathroom use as it can last up to a high 60 days. The downside is you have to constantly remove and change the batteries, unlike a renewable dehumidifier that can be recharged when needed.
  • Heated Rod - Another dehumidifying option that is placed underneath the closet, wardrobe, or locker. Heating rod electric dehumidifier works by heating the air to 150 degrees Fahrenheit. When the air is warm, there is better airflow circulation in the closet thus less moisture will linger around.
  • Electric refrigeration dehumidifiers - The most common type of electric dehumidifier in the market. A refrigeration dehumidifier works by drawing damp air into the coil to perform condensation. The water vapor in the air will be extracted out and either drip down to the reservoir or straight to the pump. The dry air will then disperse out as mist. If you want to effectively reduce the humidity level in the room rather than just the closet, this is the one. Be prepared to pay for a hefty price though especially on 70-pint model.
  • Thermoelectric - Commonly found in small dehumidifiers that offer efficient and silent operation. A Thermoelectric dehumidifier uses Peltier technology to pull moisture out of the air. The water vapor will be collected in the bucket and a person will have to empty it every 1-3 days. Because of that, thermoelectric is not the best solution for cabinet or wardrobe as you have to constantly manage the water level.

How Do I Get Rid of Humidity In My Closet?

A desiccant dehumidifier is the best way to get rid of humidity in the closet. We are not referring to those cheap, one-time use desiccant bag that contains charcoal, baking soda, chalk or calcium chloride salt. We are referring to a desiccant dehumidifier that uses silica gel to extract moisture in the closet through adsorption. It is far more effective than the disposable desiccant products and eco-friendly as it can be recharge and reuse many times.

How To Remove Mold From The Closet

Closet can be the perfect breeding grounds for mold as it is dark and damp. When your closet is already infested with mold and mildew, a desiccant dehumidifier won't do the trick in removing existing fungus. Instead, here are the things you could do to save your garment and wardrobe from mold attack.

  • Use mold control spray or other mold removal products to effectively kill off existing mold in clothes or closet. The applied surface will also act as an antimicrobial that prevents mold and mildew re-growth. Easily available in all local hardware stores or retailers.
  • You can use detergents like Chlorine, ammonia, talcum powder, or borax to kill off any surface mold. Just mix it with water and start scrubbing the mold-infested area in the wardrobe.
  • Hydrogen Peroxide is also a good alternative to get rid of mold and musty smell in the closet. Applied a few drops to the impacted area and start scrubbing in a circular motion.
  • Better yet, use toxic-free items like vinegar, baking soda, or lemon juice that is safer and is available in every household. Leave it for a couple of hours and wash it out with water.
  • The mixture of tea tree oil, cinnamon, thyme, or clove essential oil like will work as well in removing closet mold.
  • A mini dehumidifier will halt mold growth by reducing the humidity level in the closet.

Clean the affected area thoroughly until there are no signs of mold and mildew left in the closet. Remember to wear rubber gloves and a face mask to avoid direct contact with the fungus.

Is Mold in Closet Dangerous?

Many molds are not dangerous and non-toxic to humans or other living organisms. However, there are molds that can dangerous when exposed as they produce mycotoxins. Mycotoxins are toxic compounds that can trigger allergic reactions and even asthma. The most notorious one is black mold that can lead to many toxic side effects when inhaled. As it is very hard to tell the mold types in the closet, it is wise to treat the mold straight away to prevent further growth and damage.

Why Do My Shoes Get Moldy In My Closet?

Mold can very easily grow on your shoes in the closet due to excess moisture and poor ventilation. To make matter worse, a lot of people will leave damp shoes in the closet or indoor which is favorable to mold growth. If you scent a musty smell with wet and slimy patches on your shoes, you will need to treat the mold straight away. Spray mold removal protection or apply baking soda to scrub off existing mold and mildew. With no visible mold fuzz on the shoes or in the closet, here is some preventive measure to keep your shoes from molding in the closet. First, ensure the air does not get stagnant by installing a closet vent or desiccant dehumidifier. That way the closet will always be dry and there is space for your shoes to breathe. Second, make sure your shoe is completely dry before storing them. The excessive moisture in the shoes is beneficial to mold. Third, check your shoes for mold patches and always clean them before placing them in the storage. Lastly for leather shoes, you can apply a thin layer of wax that will act as antimicrobial protection.

Why Is There Moisture In My Closet?

The reason why clothes in the closet feel damp is due to condensation. Condensation occurred because of cold air from the outside causes warm air from the inside to lose heat. The temperature differences and cooling effect will form water droplets.

To keep moisture out of the closet, here's what you need to do.

  • Add insulation to walls, ceiling, or basement to stabilize temperatures and reduce condensation.
  • A desiccant dehumidifier will absorb excessive moisture in the closet or wardrobe.
  • Allow damp clothes, footwear, linens, or towels to dry completely before storing them in the closet.
  • Ensure clothes, garments, or other storage items are washed and mold-free before putting them away in a closet.
  • Never store worn or dirty clothes in the closet. Soil and dirt could be filled with biological contaminants like mold and will spread to your other clean clothes.
  • Avoid hanging clothes too tightly into a closet. Leave some space between the clothes for better airflow circulation.
  • Keep the closet door closed in a high humidity environment like a bathroom or basement.
  • Install exhaust fan, closet or cabinet ventilation to improve air circulation.
  • Avoid drying clothes indoors and close to the closet.

Why Do My Clothes Smell Musty In My Closet?

High moisture and stuffy air is the main cause of musty, smelly clothes in your closet. When you hang damp clothes, towels, or linens in the closet, the water vapor will be stuck inside for a long period of time. This creates a moist environment that fosters the growth of mold and mildew. As a result, you will smell a nauseating, musty odor every time you open the closet or wardrobe.

How Do I Get The Musty Smell Out of My Clothes Closet?

First, ensure there is no mold growing on your clothes in the closet. Next, keep the closet smelling fresh by placing an open container with baking soda to absorb the odor. Coffee ground, dried lavender, and potpourri are less effective but doable as well. For clothes that smell bad, re-wash it again but this time, add a tablespoon of white distilled vinegar and mix it with the detergent. Last but not least, use a renewable desiccant dehumidifier to absorb excess moisture in the closet.
