- Compressor Dehumidifier VS Semiconductor Dehumidifier VS Desiccant Packet
When rainy days come, dehumidifier would become a hot key word on shopping platforms. The large varieties make customers spoiled for choice. Before we cut to the chase, let’s first figure out: do I need a dehumidifier?
Proved by experiment, humidity of 70% is the most preferred range for molds. It’s highly possible that walls and clothes begin to mildew. Our close-fitting clothing will become uncomfortable to wear due to the increase of friction caused by additional water. Even if the temperature is at a comfortable level, we can still feel stuffy and hot. When the relative humidity (RH, refers to the humidity saturation percentage of the air in certain volume) keeps going up to 100%, excessive water in the air will condense into droplets, attached to almost every object indoor. Therefore, having a dehumidifier at home not only removes redundant moisture, but also keeps it fresh and healthy indoor.
Three typical dehumidifying product types are compressor dehumidifier, semiconductor dehumidifier and desiccant packet. Here we will study their differences by making clear their respective working principles.
Compressor dehumidifier is mainly composed of compressor, heat exchanger, fan, water container, casing and controller. The fan draws moist air into the machine. After passing through the heat exchanger, the water molecules in the air will be condensed into water droplets and discharged. At the same time, the treated dry air will be blown out of the machine. This is how a compressor dehumidifier keeps the indoor humidity at an appropriate relative humidity.

The scientific design results in high-efficient dehumidification effect, which covers of a relatively large area. However, with such components inside, the machine will not be much friendly to your bills for purchase and electricity. Also, it tends to be half-man tall and noisier. To sum up, compressor dehumidifier is suitable for spacious places such as shopping mall and library.
The key how a semiconductor dehumidifier removes moisture is through semiconductor refrigeration fins. After the fins are energized, they will form a cold end and a hot end. When the air with higher moisture flows through the cold end, part of the water vapor condenses on the surface of the cold end, precipitating water beads. Later the condensed water is collected and discharged through the collecting tank.

With an outstanding dehumidifying performance, it costs less electricity and occupies smaller space. Compared to the inside structure of compressor dehumidifier, this is simpler and quieter. Therefore, this kind of dehumidifier is more easily to come with a compact and fashion design, perfect for use at home, especially on the desk / beside the bed.
The working principle of a desiccant packet noticeable by its appearance - upper bag filled with porous material and the lower one is to collect water. The surface area of the porous material is used to absorb moisture from the air. Since the partial pressure of water vapor on the surface of the solid moisture absorbent is lower than that in the air, the moisture in the air is absorbed to achieve dehumidification effect.

The biggest advantage of using desiccant packet is that you can have a direct and quick perception of its dehumidification effect. No noise or power consumption - it costs a lot cheaper even you purchase in bulk. The only thing less satisfying is that one packet can only be used once and each for a short time. Anyway, its small body makes it easier to be placed in wardrobe or storage rack.
After overviewing three kinds of dehumidifying products as well as their pros and cons, you may now have a comprehensive understanding of what fits your need. The key to choose falls on the size of the area from which you want to remove excessive moisture. You also need to consider whether you have enough space to accommodate the machine and the sound will affect your work and life or not.
