Need For Dehumidifiers in Basements

In many developed countries, many houses have a basement. A basement can serve a number of purposes including providing storage for your belongings, furniture, and other household appliances. One important issue plaguing almost all basements is the quality of air and moisture control. These factors can determine the durability of the items stored there.

To meet these challenging needs, basement dehumidifiers have proved up to the task. These devices are made specially to counteract the environmental challenges posed in the basements as a result of the extra moisture present in these underground areas of the home.

While many blame heat for most noticeable structural damages in items stored in the basement, research has shown that heat alone may not be the problem, rather the circulation of air in your basement. What you need is a dehumidifier as it quietly reduces the humidity of your basement by extracting excess moisture from the air.

It doesn’t cost much to buy a dehumidifier, depending on its working capacity and its size. Keep in mind though that not all dehumidifiers are good for your basement.

The best indoor air humidity level for a healthy basement is between 30 and 50 percent. So when shopping, read the specifications to be sure the dehumidifier you are buying can provide this standard.

We understand it can be stressful combing the markets for the best quality, so we have done the homework for you. We present you with the best dehumidifier for a basement you can get.

Dehumidifier Features to Lookout for When Shopping

Some features come with all brands while other features are specially designed for special models. Here we take a look at some features you might want to check out before making a purchase.

Air filter — This feature is what helps to clean the air that the dehumidifier collects. As the air passes through the dehumidifier, the filter purifies the air for circulation.

Pint capacity — This is the number of moisture pints that it can remove from the air within 24 hours. This factor can be affected by the size of your room and the weather condition. The best dehumidifiers for your bedroom will have a pint capacity of around 70.

Collection tank — This is an internal removable tank that collects water for easy disposal. Ensure you empty the tank periodically.

Noise level — The purpose of buying a dehumidifier is to improve your sleep. Buying a noisy one defeats that purpose. It is recommended to buy one of 50 decibels or less.

Automatic restart — When power fails, having this feature will help it start again without your input.

Automatic shut-off — Thus helps the device to turn off even though it is still connected to a power outlet.
