Dessicant Dehumidifier - Reviews and Buying Guide

There are various ways dehumidifiers work in successfully removing humidity from a desired area. The most common would be the refrigerator coil dehumidifier. Also available are desiccant dehumidifiers. A desiccant dehumidifier is a great way to control your humidity levels.

Desiccant refers to a hygroscopic substance that stays in a state of dryness. The material works by absorbing water, which means that it can be used successfully to remove humidity. These types of dehumidifiers are made so that the air flow passes through the unit, through a chamber with the desiccant material. There is a second fan system that passes hot air through the desiccant material to extract the water into a reservoir.

Another great advantage of desiccant dehumidifiers is that they can work, and stay effective, at very low temperatures. The refrigerator coil style units can freeze and break or start becoming less effective when the temperature gets low. Conversely, desiccant dehumidifiers are not affected by low temperatures.

Desiccant dehumidifiers usually weigh quite a bit less than refrigerator coil units. This makes them ideal as one room solutions or portable dehumidifiers as they are very easy to move around.

One disadvantage of using a desiccant dehumidifier is that they cost a lot to operate. The way they are designed with producing heat to extract the water from the desiccant material means they’re about 50% less energy efficient then their refrigerator coil counterparts.

Desiccant dehumidifiers can be used everywhere, for example:

  • Basements (finished/unfinished)
  • Apartments/Condos
  • As room specific solutions
  • Insulated Garages
  • Weather proof cottages

There are many different desiccant dehumidifiers on the market today, from portable to stationary in most pint sizes. Here are the top rated options:
