If the humidity level is high, furnishings and insulation can be damaged due to the high humidity level. For those who live in an area that has a humid climate all year around, high humidity is not only present in springs but also in summers, autumns and winters.

It is recommended that the humidity level should be maintained between 35% to 45%. It is a little difficult to know the specific humidity level in the home, unless a very high humidity level is present. In order to get the accurate humidity level in your home, you can use a hygrometer to measure. On the other hand, if the humidity level is very low and a home is very dry, some problems will also happen. In this case, a humidifier is needed to add moisture in the air.

If a high humidity level is usually present, how to remove excess moisture must be taken into account. Any mold or mildew also needs to be removed and cleaned. Any damage should be repaired as soon as possible.

Maintain a proper humidity level in the home is very important. If excess moisture is present, we need to do something to remedy the situations, which can minimize health issues and damage. A dehumidifier is a great appliance to help reducing moisture as soon as possible.

Dehumidifiers are welcomed due to their convenience and ease of use. A portable dehumidifier only cost you from $100 to $600, while a whole-house unit will cost you more than $1,000. Mostly, we only need a portable unit and the following buying guide based on a portable unit.

How to Pick a Dehumidifier:


A dehumidifier capacity is measured with how many pints of water a dehumidifier can collect per day. Capacity is usually between 25 pints and 70 pints. Some large units are much higher. A dehumidifier with a capacity of 30 pints is sufficient enough and effective in 1400 sq.ft. scopes. If you need to dehumidifier a larger room, you can choose a larger unit with more capacity. Remember most dehumidifier requires emptying the water collect bucket manually. Therefore, you need to calculate how long you need to empty the bucket. This depends on the humidity level present in the air.


If you need to dehumidify a large area, choose a unit with a larger capacity. However, this doesn’t mean a unit with a high price tag has a greater capacity. Sometimes, 2 small units may be better than a large one. And the cost for 2 small units is less than 1 large unit. For example, if you have 2 rooms that are not next to each other and want to dehumidify them, you’d better buy 2 small ones.

Physical Size:

If you need to move a dehumidifier from one room to another, the portability should be taken into account. For someone who cannot lift heavy things, the physical size should be considered. General, the physical size has a relationship with the capacity. If you don’t have enough storage space or cannot lift heavy appliances, you don’t need to buy a larger size one and you can buy 2 or more small units that are easy to move and store in off seasons.

Caster Wheels

Besides the physical size, wheels are also essential. Caster wheels make it is easy to move it among different areas, empty the bucket and turn it around for easy maintenance.

Draining Option

If one has this feature, the full water bucket doesn’t need you to empty and it can drain water automatically. If you need a unit to work continuously, this feature is essential, because you don’t need to manually empty the bucket once it is full. Many units offer the drain option on their back, but the drainage hose may be not offered. Before making an order, confirm this if you want it to drain automatically. Or you need to buy one.

Position of the Water Bucket:

The bucket is used to collect moisture, so it should be easy to remove and access. You’d better choose a frontal place dehumidifier that is easy to access and remove, because you don’t need to turn it around each time. The size, weight, as well as the specific handling of a full bucket should also be considered, because it requires you to empty.

Other Special Features:

How to accurately control the humidity level? To solve this problem, the following features are essential. If a unit has a humidistat or humidity level settings which allow you to adjust, you can accurately and conveniently control the humidity level in your room. Some other appliances may also come with a dehumidifier function. If you need them to improve the comfort level in your home, you can choose these multifunction appliances that include a dehumidifier function.

Energy Star Qualified:

There are so many factors that can increase the moisture and we cannot remedy them one by one. Therefore, generally, we need a dehumidifier to run continuously. The continuously operating time may be several days. In this case, you might need to save energy and an Energy Star qualified dehumidifier can help.

Easy Maintenance:

Regular maintenance includes removing water bucket, placing a filter, etc. Therefore, it should be easy to access the water bucket and the filter and it is easy to remove them. In off seasons, we need to clean it. Make sure all the components are dry before storing.

Safety Features:

Once the bucket is full of water, it should be automatically shut off and a humidistat is also needed. Once the humidity level reaches the set level, it should turn it off automatically. If you need one to run in your living room or bedroom, the noise level should also be considered.
