Choosing a dehumidifier to suit your basement well can greatly help you to keep the area dry, cozy, and free of mold. It is important to keep in mind that not all dehumidifier models have the same features, and recognizing the main features can help you make the right decision.

1. Capacity and Coverage Area

Capacity is the first aspect that needs attention, and it is generally expressed in pints per day. A greater capacity unit is needed for larger basements or when there is moisture that cannot be removed easily. Be sure to follow the area of coverage suggested by the manufacturer to confirm that your basement is safe enough.

2. Humidity Control and Settings

It is advisable to invest in a dehumidifier with variable humidity features. In a majority of cases, it is automatically controlled by an integrated hygrometer that takes the humidity measurements and keeps the desired range. If we talk about the proper humidity, it keeps the mold off your furniture, the gadgets, and the stored items.

3. Continuous Drainage Option

New water is likely to be accumulated in the basement and constantly emptying the water from the tank is a very tedious process. If your dehumidifier is equipped with a continuous drainage or a built-in pump, the water will be transported directly through the drain to the outside of the room, thereby reducing the time of maintenance and the probability of overflow.

4. Noise Level

The noise emission from the dehumidifier should be taken into consideration in a situation where a basement is intended to be a living space or a home office. Find out if there are units that work at low decibel levels or have a "quiet mode" feature so that your dehumidifier is operating at maximum efficiency without interfering with daily routines.

5. Energy Efficiency

As a dehumidifier can be on for several hours or even all the time during hot and humid months, energy efficiency is a must. Energy Star–certified machines draw less power to the extent that the performance remains, thus contributing to the reduction of utility costs.

6. Additional Features

The contemporary dehumidifier may come with a smart control, a timer, a washable filter, and an auto-restart function after a power failure. All these features add to users' comfort and make the machine work better in the long run.

By carefully evaluating these factors, you can select a dehumidifier not only capable of dealing with your basement moisture efficiently but also providing you with long-term reliability and energy savings.

The most suitable dehumidifier for the basement of the house is the one which has the biggest capacity. These dehumidifiers are made especially in such a way so that they can remove a big amount of moisture from the air of the house in case of water-logged basements. It turns out that these dehumidifiers also become available with a reservoir that can store large amounts of water where you can empty it less often.

Should a dehumidifier be running all the time in the basement?

Of course, it is best to always have your dehumidifier running if the basement is prone to moisture or high levels of humidity. In this way, a dehumidifier will not only help to keep humidity under control but also inhibit the growth of germs and fungi which may be a result of the humidity. Also, if a dehumidifier is running all the time, it will contribute to the lowering of the total moisture in the air thus, a healthier environment will be made possible.

By the way, a basement dehumidifier, can, in addition to that, make basement odors disappear, thus, becoming a nice place to spend time in.

What is the best dehumidifier?

The best type of dehumidifier is the one that suits your needs and considers your surroundings. In general, it is more advisable to have a dehumidifier with more capacity, large water tanks, and with adjustable humidity settings. Portable dehumidifiers also are a good option for small places and for those who do not like to commit to a full-sized unit. Furthermore, dehumidifiers that have pumps are perfect for homes and businesses that have higher ceilings or basements as the water can be pumped away from there.

How do I choose a basement dehumidifier?

It is really important first to know how big your room is before thinking of a dehumidifier. Measure the size of your room so you can pick the right sized unit for you. You should also note the moisture level in your basement as some dehumidifying appliances work most efficiently in highly humid spaces.
