In addition, while you are here – why not take a closer look at popular Dehumidifiers by clicking on any of your preferred brands provided below…

Types of Dehumidifiers:

1, Refrigerant Dehumidifier – performs better at higher humidity levels and higher temperatures by bringing the air in across a series of cold coils when condensation occurs to a water container collector.

2, Desiccant Dehumidifier – more suited to lower temperature levels by bringing the air in across an adsorbent surface removing the moisture and after some heating the water then is collected in the water container collector.

Energy Consumption:

The level of energy consumed by the Desiccant Dehumidifier is higher than the Refrigerant Dehumidifier as the Desiccant Dehumidifier uses the heating process of the surfaces so take this into consideration also.


The best brands for Dehumidifiers are typically those that have been in the industry for the longest period so always use a brand that is well known and trusted and better still use a brand that you have used before that you can trust and ideally a brand that is manufactured in the US to support home grown industries.

Price levels:

The amount you spend will depend largely with the power level, the additional features it has to offer and also the capacity it can hold. Some prices can be got for $150 while other will be $500+ and the cheapest is not always the best as it may cause more problems in the long term so make sure you research wisely – don’t just pick the lowest price.


The size and capacity will also be important as it indicates how much water they are able to hold – the lower priced models will have a capacity around the 30 pint level while the larger and more expensive models will have a capacity of 70 pints and sometimes more. If there is just a small room that needs it, then choose a smaller 30 pint maximum capacity but if you wish to use it for the entire house then go for a 70 pint+ capacity model. There are 2 types of capacity – the first is the water tank capacity which is how much water it can hold and second is the Dehumidifier capacity which is how much water it can draw over the 24 hour time period so take note of the difference when doing your research.

Water Extraction Levels

The model you buy should indicate the level of water that can be removed over a 24-hour period in a condition of 60% to 80% relative humidity. The level of water extracted per day is generally a lot more than the water tank capacity so you will need to have it emptied manually or have one with a built-in pump or allow it to flow out in a low level drain.


How mobile do you need the appliance to be? If you intend to be moving it around your house frequently then make sure the model has castor wheels included so you don’t have to worry about lifting it from place to place.

Water Drainage:

Check where you plan to place the Dehumidifier in advance and see if there is a low level drainage for the water to flow. Some models only have the water tank which needs to be emptied manually while others have a pump included so that you don’t have to worry about the task of regular emptying. So, check out for these individual features depending on how you want to handle the water disposal.

Energy Rating:

The models that have received the energy star rating will also help save you some money with your power and electricity bills so choose a model that has this certification included as standard.

Timer Settings

Instead of having the appliance turned on all the time – you can also save money by using the timer settings so it will only operate at designated times of the day.

Cord Storage:

To avoid accidents like tripping over the cord or simply having it getting in the way, check out for dehumidifiers that have a cord storage included so that it can be put out of the way neatly and tidy without any fuss.

Self-Optimization – Auto Set

Some higher spec models will allow you to have the setting where it can be optimized naturally within its own environment without you having to continuously turn it on and off – it will increase or decrease automatically depending on the level of moisture in the air with its auto setting built in so again choose this feature if this is something you think you will need.

Speed and efficiency:

The speed at which the appliance can remove the moisture from the air - the more efficient it will be rather than models that are very slow and use a lot more energy and time to get the same job done.

Target Humidity Levels

The target humidity level in your home should be around 50% to prevent the onslaught of allergens such as mold and dust mites and for protecting the wooden structural integrities.  Anything over 60% is considered high and you should look at investing in a dehumidifier to reduce allergy symptoms and to make your overall living spaces drier, protected and more comfortable to live in.

If you are unsure, perhaps try something that requires little investment initially to test it out and perhaps go for an upgrade down the road when you are more confident and more comfortable with using them.
