Buying Guide for Portable Humidifiers

The features that you need to consider when buying a humidifier unit will depend on the purpose for which you are buying it. Below is a list of the top features to look out for when purchasing a portable humidifier.

1. Size and Weight:

Portable humidifiers are usually lightweight and compact in size, making them easy to carry around. However, some machines may not be as compact as others so you have to check the size of your machine before purchasing it from the store. Smaller units tend to be more portable and easy to carry around while larger units can do more work and provide greater benefits but they may not be as easy to move around with if you are on the move all the time.

2. Power Source:

Portable humidifiers can run on power or batteries. You can purchase a machine that runs on batteries or you can go for a machine that runs on regular power sockets. The advantage of machines that run on batteries is that they are more portable and you do not have to worry about plugging them into an electrical outlet every time you need to use them. The disadvantage of battery operated units is that they tend to run out of power more quickly than machines with regular power sources and they may not be as powerful as the regular ones either.

3. Humidification Capacity:

The higher the capacity, the more moisture the unit will be able to produce which translates into better results in terms of comfort and health. It is therefore important to make sure that you purchase a unit with a high capacity so that you can enjoy the benefits of having one at home. Some portable humidifiers even come with their own reservoirs and this feature gives you more control over the amount of moisture in the air.

4. Filter:

Portable humidifiers come with different types of filters and it is important to make sure that you know what type of filter your machine has before purchasing it from the store. A unit with a HEPA filter will be able to remove more allergens from the air than other models without any filters and this means that your air will be cleaner and healthier if you have such a unit in your home or office.

5. Ease of Use:

Some portable humidifiers are easier to use than others and you will have to make sure that you invest in one that is easy to use. You should be able to fill the water tank, switch it on and adjust the settings without any issues. It should also be easy to clean and maintain so that you can be sure that your machine will last for a long time.
