Dehumidifiers are required for making sure that high humidity doesn’t damage the house and its structure. While this statement might seem like a bit too much to many, but people living in climates with high humidity have to deal with such a situation pretty commonly. The worst place in the house to be hit with all this is the basement because it is the one place in the house which lacks natural ventilation of air and so have the highest chances of getting molds and other issues which can not only harm the house but also the people living in it.
So let’s talk about the types of the best dehumidifier for basement:
Heat pump dehumidifiers
These extract water from the surrounding air by using up a heat pump which is quite similar to a pump present in an air conditioner. Here, a fan present inside the machine pulls the indoor air across a very cold coil which inadvertently causes moisture to condense, then these droplets drip down into a bucket which is then pumped out through a hose. The dry air is warmed up by a heated second coil. These dehumidifiers are generally considered to be the most effective.
Chemical absorbent dehumidifiers
These use a chemical drying agent in a heat exchanging wheel so as to absorb up the water molecules present in the air. Then the damp air is sent outside using vents. You should note that these dehumidifiers use up a lot of energy and are most commonly used by industries. But these are also the best used in warm climates. So it’s a toss-up really between the climate you live in and how much energy you are willing to let it consume.
These dehumidifiers have a sensor controller as well as an exhaust fan. It works when the sensor controller activates up the unit as the humidity reaches a very specific level. But these are less effective in hot and muggy climates because they draw in outside air into the house. Yet these are pretty commonly used in basements even though they can depressurize the room and cause gas spillage. So if you have gas furnaces then make sure that they are properly vented.
This is not to say that any of the three types are bad or useless as the notes given here have been chosen keeping in mind the usefulness of the technology in regards to basement needs.
