Best Dehumidifier for Basement: Buying Guide, Reviews With an Infographic

It is important to maintain the right level of humidity in the air inside your home and specifically in your basement. This is because underground basement is one of the places which is devoid of natural air. As a result, the air is always loaded with moisture which leads to the growth of mold, mildew, and allergens. Nevertheless, a good dehumidifier can help you maintain the right amount of moisture in the air.

Signs of a Humid Basement

  • Musty odor in the air

A humid basement is often characterized by a musty odor caused by the presence of mold and mildew in the air. One can easily identify mold as it leaves little dark spots around the walls. These are caused due to the excess levels of humidity in the air in the areas where there is no proper ventilation.

  • Condensation

Depending on the condition, you might also see signs of condensation on walls and floors. Signs of condensation show small drops of water or fog on the glass or on the walls. A good dehumidifier soaks all the moisture and keeps the place dry.

  • Water runoff

This is the most common problem often experienced in basements. This may be due to water seeping or due to poor water pipe fittings or accumulated water in the rainy season.

  • Rotting wood

If you find any rotten wood in your basement, it definitely needs a dehumidifier. Wood usually starts to rot when it retains moisture for a long time. A dehumidifier can help in removing the excess moisture out of the place.

Best Dehumidifier for Basement Buying Guide

  • Water removal

The dehumidifier should be able to remove at least 20 pints of moisture from the air every 24 hours. The pint capacity of the dehumidifier is the most important criteria. Make sure it is able to remove the right amount of moisture from the required sq. ft. area.

  • Tank capacity

The more water your tank can hold, the less often you would need to empty the tank. The collection tank or bucket should be appropriate and in tune with its pint capacity.

  • Control panel

The dehumidifier should have an easy to comprehend control panel. It would either have electronic controls or manual controls. Electronic controls are either digital or have a touch panel. However, electronic controls lose their settings in case of power cuts, whereas manual controls don’t. Nowadays auto power on-off is prevalent even in cases of an unexpected power cut.

  • Overall size

The dehumidifier should be portable enough that you can carry it from one room to another. Choose a dehumidifier with at least one handle and castor wheels for easy mobility.

  • Filters

Choose a filter which is capable of catching mold and mildew and can be washed at home. Make sure the dehumidifier has easy to remove, washable filters and pre-filters.

  • Noise

It is needless to say that you should choose a quiet dehumidifier over noisy ones. The continuous process of air filtration generates noise which can be quite distracting.

  • Low temperature

For a dehumidifier to be able to work suitably in the basement, it should be able to work well at even low temperature. It should be another important criterion to look for when buying a humidifier for the basement.
