Buying Guide For Dehumidifier For Large Basements

Why do you need a Dehumidifier: The first thing to consider when purchasing a dehumidifier is the reason you need to have one. Would there be a difference if you didn’t get one? To answer the question, yes there would be a world of difference. For starters, your basement would get to lose that musty dampness smell that comes with very humid basements. You’d also be safeguarding your health and that of every other person that frequents the basements. Health issues such as Asthma and other allergies can easily be triggered by the high levels of humidity. As long as there is a humidity problem, getting a dehumidifier for your basement is very much essential and necessary. However, if the humidity level in your home is perfect then you may not need a dehumidifier.

How large is your basement: Of course, the size of your basement is a major factor to consider when you need to get the best dehumidifier for large basements. A dehumidifier works by reducing the humid levels in the surrounding space so the size of the space is a major factor to consider. To ensure the efficiency of your dehumidifier, it’s best to select size of your dehumidifier based on the square foot of your basement. The capacity of a dehumidifier is measured in pints; that is, the calculated amount of moisture that can be removed from the air within 24 hours. For large basements, a 70-pint dehumidifier or larger commercial sizes are the best options to consider.

How will I eliminate collected water: During the process of dehumidifying, water is collected from the surrounding air and the air with less humidity is returned out. Some humidifiers come with a bucket or drain pan to collect the water. Once full, the appliance automatically shuts down to avoid spill or over flow. In most cases, the bucket would have to be emptied manually but a pipe can always be connected to the bucket to ensure ease of drainage. This is one of things to put into consideration when buying a humidifier. Be sure to ask how your selected dehumidifier eliminates the collected water.

Noise level: It can be a huge nuisance if you only find out how much noise the dehumidifier makes after it has been installed. So when buying a dehumidifier, you’ll need to ensure that the noise level is suitable for the space you plan on installing it. Of course a large dehumidifier for basement will most likely be a bit loud. But the noise level should still be as minimal as possible.

Useful additional features: Different models of dehumidifiers come with different features that may be quite useful to you. Consider if the model you’d like to purchase has some of these useful features. Some of which include; timer that allows for programming to specifications, adjustable humidistat, constant drainage that relieves you of the stress of manual draining by connecting your pipe to a drainage system, in built pump, auto restart and many more. Carefully decide on which features fit your purpose and are most beneficial to you.
