Factors To Consider When Buying Best Battery Powered Dehumidifier

a) Size and Capacity

There are essential specifications to consider when choosing a battery-operated dehumidifier. It's key to ensure that you select one that will suit what you're looking for. Dehumidifiers have a maximum moisture capacity they can absorb, and it's measured in ounces or milliliters.

It's worth noting that some dehumidifiers work best when placed in an appropriately sized area. Most dehumidifiers indicate what sized area the unit works best in, measured in cubic feet or square feet.

Cubic feet and Square feet are two different measurements, so it's vital to be precise when measuring your space. If you want to reduce the humidity level in a large room, a mini dehumidifier won't be ideal.

b) Design

It's always advisable to consider the design of a battery-operated dehumidifier before purchasing. The best battery-powered dehumidifier will be one that fits where you'd like it to.

Below are the different types of dehumidifiers:

  • Refrigerator-Style: This style tends to be the most common. They take in the humid air from a room and cool it, thus dehumidifying the air. They then release the cool air back into the room. However, they aren't suited for cold climates as they can only cool air to specific points.
  • Desiccant Dehumidifiers: Their dehumidification process involves taking in air and passing it over a desiccant material like silica gel crystals or silica gel beads, which absorb water. They work well for cold climates.
  • Mini Dehumidifiers: They are ideal for small spaces and are often more affordable and come in corded and cordless versions. The cordless versions are plugged straight into a power outlet or run-on batteries. Many use the same silica gel technology as their desiccant counterparts.
  • Portable Dehumidifiers: Though portable, many still need electricity or an outlet.

c) Recharge Time

The recharge time for a battery-operated dehumidifier varies by brand. It can take anywhere from two to fifteen hours to refresh silica gel beads. Therefore, it might be best to purchase multiple dehumidifiers so you never end up without one when you need it. This lowers the risk of developing mold and mildew.

d) Automatic Shut Off

An overflow protection causes the dehumidifier to switch off when the tank is full and needs to be emptied. This is a key feature to have when searching for the best battery-powered dehumidifiers. In addition, some feature indicator lights to show when the water tank is full.

e) Energy Efficiency

The best battery-powered dehumidifier that carries the energy star label allows you to save money on utility bills. In addition, it means the unit is energy efficient. Dehumidifiers certified with the government-sponsored label are assured to use less energy yet run efficiently.

f) Quiet Operation

If buying a dehumidifier for use with a baby or in a bedroom, it's best to consider those equipped with Peltier technology that guarantees low noise. Ideally, you want battery-operated dehumidifiers with two-speed fans as they run quietly at lower humidity levels. They also save on energy costs.

g) Humidity Control

The key reason for purchasing a dehumidifier is its humidity control.

Ideally, you want to look for one with automated controls for monitoring and setting relative humidity levels.

Homes must have an optimal humidity level of between 40% and 50% in summer and 30% and 50% in winter. A dehumidifier with a built-in hygrometer measures relative humidity and displays the number.

An adjustable humidistat allows you to dial the desired humidity level, and the unit will automatically maintain it.

If the battery-operated dehumidifier you select does not feature these settings, you may want to buy hygrometer to hang next to the dehumidifier.

h) Easy To Use

Rechargeable dehumidifiers should be easy to operate. However, you don't want a unit that will be complicated and hard to figure out. One way to figure this out is by reading other customer reviews.

Benefits Of Owning A Dehumidifier

1. Helps with allergies

Humid environments tend to be the best breeding ground for dust mites, mold, and mildew which trigger allergens. In addition, rooms where water is used or poor air circulation, like laundry rooms and bathrooms, can be especially prone to harboring allergy-causing substances that can spread throughout the house.

A dehumidifier can decrease the excess moisture that supports allergen growth, improve air quality, and aid in preventing some types of bacteria and virus growth.

2. Reduces pest related problems

Humidity also encourages the growth of pests such as spiders and roaches as they tend to gravitate towards moist environments. Having a dehumidifier can help lessen their visits. It's vital to pay attention to the room where you see the most pest activity, and if there are rooms where water is present or humidity is high, you may have found the root of the problem.

3. Controls moisture levels 

High levels of moisture can result in structural problems over time. This is because condensation can build up, causing mildew and mold to form and warping and deterioration. Furniture can also be damage from long-term humidity and high moisture. If you notice the paint or wallpaper peeling, unusual stains, or a musty or moldy odor, you may require a dehumidifier to help prevent additional damage.

4. Improves comfort

Generally, a good dehumidifier makes your life more comfortable. It improves the air quality, and the air stays cooler.

5. Reduces energy costs

A dehumidifier can help control energy costs by helping your air conditioner work more efficiently. It works to remove extra moisture from the air, meaning your air conditioner doesn't have to work so hard to maintain a cool and comfortable temperature. Thus saving energy use and as wear and tear on your cooling equipment.

Frequently Asked Questions About Best Battery Powered Dehumidifier

a) How Long Do Rechargeable Dehumidifiers Last?

Rechargeable dehumidifiers that are cordless and don't use batteries can last up to 10 years. However, it's worth noting that the relative humidity, recharging frequency, and the silica gel beads volume will significantly affect the longevity of the dehumidifiers.

b) How Do Rechargeable Dehumidifiers Work?

They work by collecting and holding moisture in the air through the tiny passages found in silica gel beads. There is no power switch, cord, and batteries needed as the dehumidification process happens naturally as long as the dehumidifier is charged.
