How To Choose The Best Humidifiers For Allergies?
It's not easy to choose the best humidifier for allergies among a variety of models available on the market. Therefore, consider the following elements before buying:
Types Of Humidifiers
The humidifier has 4 types as follows:
Cool mist humidifier
Warm mist humidifier
Ultrasonic humidifier
Whole-house humidifier
Warm Mist Humidifier
- As the name suggests, this type of machine produces warm mist for smoothing the air. It creates clean air quietly, so I strongly recommend you use it in the bedroom. However, this model requires more time and effort on your end for maintenance.
Cool Mist Humidifier
- This machine is designed with a filter, which helps you trap all minerals and pollutants to produce a very fine and cool mist. In particular, it has better coverage than warm mist. Thus, you can use it in the baby room where it requires a high level of clean air. Although you need to replace the filters frequently, it's effortless to clean them.
Whole-House Humidifier
- This model is for heavy-duty tasks because it is able to cover a large space. Though the installation requires you to spend more time, the performance is very effective. It can help you humidify your whole house with minimal maintenance. This machine operates with a tank that just requires you to refill every few days.
Ultrasonic Dumidifier
- This is a safe choice for the baby room because it won't humidify by creating heat. Instead, the ultrasonic model will vibrate a metal diaphragm at an ultrasonic frequency, generating water to output into the air. Apart from safety, these machines are pretty quiet and easy to clean.
Coverage
- Before purchasing any humidifier, you have to determine your product's coverage capability in square feet. This feature tells you whether it works well in a small or big room. The majority of single-room humidifiers reach from 200 to 500 square feet. Meanwhile, you can expect some whole-house humidifiers to reach more than 4000 square feet.
Cleaning
- If you don't clean and maintain your humidifier correctly, the accumulated mold and bacteria will disperse into the air. In case you use a machine with UV or Silver Clean Protection technology, it can prevent the development of bacteria.
