What to Look for in a Good small Dehumidifier for Bathroom and Bedroom

What to Look for in a Good small Dehumidifier for Bathroom and BedroomHave your had the best Dehumidifier for bathroom and bedroom for your house?

The bathrooms are usually the dampest place in our house because of their nature of use. With hot showers and baths, it means that the humidity of your bathroom is always at a high number. If you use your bathroom, especially when it has bad ventilation, you can easily spot condensation and mold in this room.

When mold and spores start to develop in your bathroom, it will make you feel unpleasant and uncomfortable. It also poses a huge risk of unhealthy potential for your well-being as well.

This also applies to your bedroom. If there is over humidity and bad ventilation in your bedroom, you will also start to see mold and mildew as well. Of course having them in your bedroom is not a good sign. Especially when you are sensitive to allergens, they will cause trouble breathing and badly impact the quality of your sleep.

The most effective and efficient way to maintain an ideal humidity and combat over moisture in the bathroom as well as in your bed room is using a dehumidifier.

In this article, I will provide the types of dehumidifiers which are best for your bathroom/bedroom as well as reviewing some of the most common products currently available on the market.

High HumiditySigns that your bathroom/bedroom is over humid

  • You see mildews and molds in the callings and corner of the bathroom. They develop from very small, insignificant spots so make sure you check carefully.
  • You can also see hints of water on windows and mirrors.
  • Paint on the walls starts to fall off.
  • There is also a strange and odd smell coming from the bathroom as well.

As you can see from the introduction, the bathroom is the dampest with highest humidity level in your house. Over humidity will cause mold and mildews which can be spread to other rooms. Also the bad condition of the bathroom and bedroom will affect the health of people who use it, especially the respiratory system. Furthermore, you would not be able to enjoy a quality time taking a warm bath and having a good sleep, which will then affect your normal healthy lifestyle.

Last but not least, it will cost you a lot of money for maintenance and repair of the bathroom and the overall house if they are damaged by over moisture. Therefore, it is very important that you come up with a way to prevent and fight against moisture and over humidity in your bathroom.

Why should you choose a dehumidifier over other tradition ways?

A small dehumidifier offers more benefits to control humidity in our bathroom than other tradition methods (including using box fan and exhaust fan. Or simply open the door all the time)

  • Firstly, it can help to control the correct and ideal humidity level.
  • Also, it offers quick removal of excessive moisture in the air.
  • Lastly, it is more energy efficient than using an exhaust fan or a box fan.

Types of Small Bedroom/Bathroom Dehumidifier

There are two mains types of dehumidifiers which are a Refrigerant and Desiccant Dehumidifier.

A dehumidifier helps to maintain the correct humidity level and capture the air and squeeze out excessive moisture before releasing the air back to the room. These two types are different in the way they extract the moisture from the air.

With a refrigerant dehumidifier, a metal coil inside this device is responsible for cooling the air and extracting the water from the air. The amount of water which can be extracted from the air is based on the different temperature in the coil and the outside temperature of the bathroom. When the bathroom is hot, it can extract more water.

With a desiccant dehumidifier, the air will be absorbed into/ onto a drying material. The excessive water will be kept in that material, and air will be released back into the room. Sometimes when the water in the air is too much, the drying material cannot hold and extract that much water and can be broken.

Typically, a refrigerant dehumidifier is more capable of extracting a large amount of water.  Therefore, it is more suitable for a room with a higher level of humidity. A desiccant dehumidifier is better in a room with a lower level of humidity.

Also, a refrigerant model works better in a hot environment, and a desiccant one is better at low temperature.

Overall, a refrigerant dehumidifier is better for the moist and hot bathroom.

Size and Square Footage Chart

When choosing a dehumidifier, one of the most important features you need to consider is the size as well as the square footage the humidifier needs to cover.

The bathroom usually has a high level of humidity; therefore it is best if you look for a humidifier which can run well in that environment.

For a high level of humidity in the bathroom:

  • A 15 pint dehumidifier needs to cover up to the maximum coverage up to 300 square feet.
  • A 15-30 pint dehumidifier needs to cover the range from 400 up to 1100 square feet.

Furthermore, with a lower level of humidity in the bathroom, you will need a less powerful dehumidifier. To put it in other word, you will need one model which can collect a fewer number of pints in the same coverage.

Tips To Choose Dehumidifier Capacity For Your Bathroom

The first thing you need to know in order to choose capacity for your bathroom/bedroom is the size of the room. In most houses, the size of the bedroom/bathroom will fall from 300 square feet to 500 square feet. Bathroom often smaller than bedroom

The next thing to know is the condition of your room. You need to decide if your room is slightly, moderate or very damp. For a small room of slightly damp condition, you can choose a dehumidifier with a capacity of less than 15 pint. If it is moderately damp or very damp one with level of humidity above 80%, you need to go for a dehumidifier with a capacity to collect up to 25 pints of water.

How about a 500+ square foot bathroom? – With a bigger bathroom, you will need a stronger dehumidifier. Go for a 30 pint dehumidifier if your bathroom is damp or very damp and has the level of humidity around 70%.
