Dehumidifier Reviews on Ionmax ION612 and ION632 by CHOICE

Ionmax ION632 and ION612

Last year, the Ionmax Ion632 desiccant dehumidifier was given an excellent review by CHOICE magazine’s dehumidifier review. This year, CHOICE has tested both the Ion632 and Ionmax Ion612 dehumidifier in their 2014 dehumidifiers review, and both our Ionmax dehumidifiers have been recommended again.

In the new report, CHOICE reviewed 22 dehumidifiers to reveal which dehumidifier would perform the best at removing water, are the most energy efficient, and are the easiest to use and clean.

Our Ionmax dehumidifiers were the only desiccant models available for the review, and as Choice mentions – “Because they don’t use cooling to extract the moisture, desiccant rotor models can be much more effective than refrigerant models in cold climates. In fact, their performance should be largely unaffected by the air temperature.”

The dehumidifiers were tested in a temperature- and humidity-controlled test chamber and three test ‘runs’ were conducted at different temperature and humidity combinations to reflect humid winter climates.

The Ion612 and Ion632 are desiccant rotor dehumidifiers, i.e. they work according to the adsorption principle, making them ideal for high humidity levels at low temperatures.   They are often used in various sectors in the industry because they can achieve humidity levels below 35%.

Desiccant dehumidifiers use a slowly rotating disc or belt of material that absorbs moisture from the air. The damp section then moves through a drying process (typically a heating element) that evaporates the water and collects it in the tank.

Because they don’t use cooling to extract the moisture, desiccant rotor models can be much more effective than refrigerative models in cold climates.

In fact, desiccant dehumidifiers’ performance are largely unaffected by the temperature of the air. As you can see in the graph below, their rate of dehumidification remains stable in low and high temperatures, making them suitable for all seasons.

Compressors, on the other hand, work better in summer when temperatures are higher, but not so much in cooler temperature.

Another great thing about desiccant dehumidifiers is that they don’t use any refrigerants and therefore are very low in maintenance. With a high extraction rate at all temperatures, portable and lightweight design, and quiet operation, desiccant dehumidifiers are fast becoming the top choice among buyers.
