Factors To Consider When Choosing Best Small Dehumidifiers

a) Noise Level

If you’re a light sleeper or you sensitive to noise, this is a feature worth considering. It’s also worth considering if you have children, as some dehumidifiers can be quite noisy. Depending on where you want to place yours, it’s essential to pay attention to the machine’s noise level. If you plan to have it in your bedroom, you’ll want the best small dehumidifier that operates quietly, allowing you to have a restful sleep.

b) Size

When searching for the best dehumidifiers, one of the ways you can narrow down your selection is by focusing on the size. The size will be determined by the living space or room you want to place the machine in.

For a small space, you’ll be best suited with units capable of removing 25 to 35 pints of moisture per day. For medium to large rooms, you’ll require a 40- to 50-pint capacity per day. As for large or rooms with high humidity levels, you’ll require a large capacity unit rated at 65 to 75 pints per day.

c) Efficiency

Generally, the higher the energy efficiency of a dehumidifier, the less energy it will consume. This means that you can expect a lower electrical bill. The energy efficiency of dehumidifiers is measured in liters per kilowatt-hour. Hence, the higher the energy factor, the more efficient the unit. To increase your efficiency, choose a machine with a multispeed fan that slows down when moisture levels are relatively low to save energy.

d) Purification

Some dehumidifiers double up as air purifiers hence allowing you to not only have improved air quality but the reduction of moisture in the air. They also help with allergens, minimizing dust mites and pet dander.

e) Water Disposal System

The main purpose of dehumidifiers is to extract moisture in the air, thus improving its quality. Most units will feature a tank that you can remove and drain. These water tanks have a maximum capacity ranging from 10 to 75 pints. The larger the water tank, the more convenient it is for you as you won’t need to empty it often.

Some units feature a built-in pump that will automatically pump the moisture out through the tube to an external drainage point. At the same time, others come with a drain hose capability, thus allowing you to connect the unit to a compatible drain hose. This is great as it frees you from having actually to empty the water tank.

e) Portability

The beauty of a portable dehumidifier is its ease of convenience. You can move around with it, whether you’re on the road or you’re moving from room to room. However, it would help if you kept in mind that you’ll have to remove and carry the water tank every time it’s full, so look for a machine with a tank that is easy to remove, easy to carry, and equipped with a cover to keep water from spilling out as you move it.

f) Easy to Operate

It’s always important to invest in dehumidifiers that are easy to use. In addition, it should have controls that are user-friendly and simple to maneuver. Essentially, the best small dehumidifiers are those that come with as many features as possible.

For instance, water level indicator that lets you know when to empty the water to prevent the overflowing of the water tank, the capacity indicator that lets you know that it’s time to empty the reservoir, or even a handle that will allow you to carry it from one room to another easily.

4. Improved Air Quality
