Compressor dehumidifiers can save 50% more electricity than desiccant dehumidifiers when they work optimally in a warm climate. Desiccant dehumidifiers work much quieter compared to compressor dehumidifiers that have a running compressor. Compared to compressor dehumidifiers, the desiccant style is also very quiet. At lower speeds, they do not exceed much 40 dB.
The lack of a compressor also means that they are much lighter, about 10 pounds less than their compressor counterparts. Both types of dehumidifiers have their advantages and disadvantages. Desiccant dehumidifiers are better in areas that are already dry and cold, while compressor dehumidifiers are better during warmer seasons, where humidity levels are already high. If you prefer to keep certain parts of your house cool, nice and warm, in this case, the compressor dehumidifier is the best option.
However, if you have parts of your house that are always cold, then you should choose the desiccant dehumidifier as it produces more heat. The desiccant dehumidifier does the same job of removing moisture from the air in rooms, but in a different way. Instead of using a compressor and refrigerant arrangement, it absorbs moisture using an absorbent material known as a desiccant. Run the dehumidifier outside and away from the VOCs to clean the desiccant wheel and then you can return to many more years of dehumidification with Zambezi.
Internal heaters in a desiccant wheel can reach up to 140°F, so by the time air is blown out into the air, the overall ambient ambient temperature could be at least 10°F warmer than the air temperature in the room. The compressor dehumidifier is probably what you have in mind if your familiarity with appliances is from a decade or two ago or from childhood. Examples of these desiccants are the ProBreeze cordless dehumidifier and the EvaDry line of mini dehumidifiers. If you have slightly lower humidity levels in your home and you simply want to remove the edge of humid air, a desiccant model often fits the bill.
If the temperature is around 18°C, then a compressor machine would be fine and cheaper to operate than a desiccant dehumidifier. Desiccant dehumidifiers have many, many advantages, but if there are VOCs in the room, they can be introduced into the dehumidifier. The thermoelectric dehumidifier also enjoys great popularity, as they are generally smaller by design and are much quieter due to their compressorless operation. The lower end of that spectrum is where you will see compressor dehumidifiers being marketed with “whisper” technology.
Compressor dehumidifiers are very sensitive to ambient temperature and can sometimes appear to remove moisture inconsistently because of this. Desiccant dehumidifiers that can remove the same amount of moisture in rooms at about 60 to 75°F are lighter, typically weighing between 13 and 20 pounds. Compressors add about 6 kg to the weight of a dehumidifier, so carrying a desiccant dehumidifier is much easier than carrying a compressor dehumidifier. But if your indoor temperature is consistently below 20°C, consider the desiccant dehumidifier as an excellent choice.
