Luckily, this article is here to help. Keep reading to find out the things to look for when buying a dehumidifier.


What Are The Types of Dehumidifiers?

So, before anything else, readers should know that there are three main types of dehumidifiers. Namely, these are the Refrigerant, Desiccant, and Whole House dehumidifiers. The difference between each of these lies in their size and the way it collects the moisture in the air.

Refrigerant Dehumidifiers

First is the refrigerant dehumidifiers. It makes use of the same processes used by your fridge at home. Moisture in the air is taken out through cooling coils or plates, the moisture is then extracted by condensation, with the extracted water is drained away. For some models, the unit would switch itself into standby mode once relative humidity in the room or home has been normalized and would turn itself back on if the need arises.

Refrigerant dehumidifiers are the most commonly in home set-ups. They are especially ideal for single room usage. It is worth noting that these dehumidifiers are most effective in spaces with average temperatures. Sadly, users would notice a decline in their efficiency and performance in cooler conditions. This is because ice crystals can form on its metal cooling coils in temperatures below 18°C.

Desiccant Dehumidifiers

This particular type of dehumidifier is the smallest and least bulky of the three. As the name suggests, desiccant dehumidifiers absorb water from the air by making full use of desiccants or drying agents. The moist air passes through a wheel made up largely of the desiccant which proceeds to absorb the excess moisture. As the rotation cycle continues, the desiccant is reactivated by warm air and the excess moisture is turned into condensed water. The ensuing by-product is excess water and warmer air. The former is then drained out through a tube for disposal.

The primary reason why you would want to make use of these desiccant dehumidifiers is their efficiency in colder temperatures. They are ideal in naturally damp and cool places like the garage or workshop. Just take note that they tend to consume more energy compared to refrigerant dehumidifiers.

Whole House Ventilation Dehumidifiers

The third type is known as the Whole House Ventilation Dehumidifier. It works by bringing in outdoor air into your space to control its humidity levels. As you may have surmised from its name, these dehumidifiers work to monitor and maintain the humidity levels in your entire home, and not just a single room. This would be the ideal choice if you wish to keep the humidity level consistent in all sections of your space. This way, you can rest assured that you will never have to deal with the problems that come with high humidity such as mold, rust, and warping.

Of course, like with all other types of dehumidifiers, a whole-home dehumidifier has its own drawbacks. Specifically, its cost as they are undoubtedly pricey. Moreover, these units also need regular maintenance which can also take time and money.



Features to Consider When Buying Dehumidifiers

When buying a dehumidifier, you must weigh your options carefully. Similar to buying a car, you need to look at what’s under the hood. The specific features would tell you whether a particular model is the one for you. Listed below are just a couple of the things you need to consider.

  • Size and Capacity – You need to take into account the power and size of the dehumidifier in relation to the area you plan to use it on. Consider the square footage of the room, office, or home you plan to use it on and look at the capacity of the model.
  • Auto-Restart Function – Look for a dehumidifier that has an auto-restart feature. It provides an additional level of convenience as you no longer have to worry about the device at all. This comes especially handy when the power goes off, as it will automatically start working again once the power outage is finished.
  • Integrated Humidistats – The Humidistats shows the moisture level in the surrounding air in real-time. This is crucial as you need to keep close track of the humidity level in your area.
  • User-Friendly Humidity Controls – Ideally, your dehumidifier should allow you to adjust the specific humidity level with ease. Look for models that make use of categories indicating different levels of dryness (i.e. dry, very dry, etc). On the other hand, if you are looking for something with more control, then look for dehumidifiers which allow you to adjust the actual humidity levels by percentage.
  • Timer Controls – Look for a dehumidifier that allows timer customization. This is a convenience that you must avail as it saves you the time and effort of having to manually set-up your dehumidifier time and again. When you find the right setting, you can simply forget that your dehumidifier is even there.
  • Constant drainage – Avoid the hassle of periodically emptying the dehumidifier’s water canister by choosing a model that sports the constant drainage capability. This way, you can ensure that the water collected goes straight down the drain.
  • Washable Air Filter – Invest in a dehumidifier that features washable air filters. This will save you money down the line as you no longer have to regularly purchase replacement filters.
