Frequently Asked Questions

Why do I need a humidifier?
Many cold symptoms, itchy skin, dry eyes, allergies, or respiratory conditions are either provoked or intensified by low humidity. A humidifier increases the moisture in the air by releasing water vapors or extra-fine drops, thus creating a more comfortable environment.

What is the ideal humidity level?
Although humidity is important for your health and comfort, it should be kept between 30% and 50%. If the moisture in the air overcomes 50%, there is a high chance that mold, mildew, bacteria, and other dangerous pests breed and grow in your house. On the other hand, if it drops below 30%, flu viruses will be the ones invading and ruining the peace of your home.

What size humidifier do I need?
The main criteria is the size of the space you are looking to cover. The larger the space is, the bigger should the humidifier be. To be sure, you can check the product’s specification list, as the area of coverage is often included there.

Is cool mist better than warm mist?
When it comes to efficiency, there’s no notable difference between a cool mist and a warm mist humidifier. They both increase humidity, reducing the discomfort in the room. However, if you have kids, a cool-mist device is recommended, as the hot water in the warm-mist can spill and cause accidents.

How often should a humidifier be cleaned?
The ground rule is that you should never leave water in the tank and use it again the next day. The tank should be emptied when the humidifier has done its job and dried with a towel so the moist surface doesn’t become a breeding ground for bacteria. Moreover, if it’s used daily, it should go through a thorough cleaning at least once a week.

Should windows be closed when using a humidifier?
Keeping the windows closed while using a humidifier can cause the humidity to rise abruptly, reaching values that are dangerous for your health. It’s best to place it in a well-ventilated space, where the windows and doors can be kept open.

Can you put tap water in a humidifier?
Humidifiers can run on tap water. However, it is not recommended. Tap water contains plenty of minerals that tend to spread into the air with the mist. Moreover, in time, they deposit on the humidifier’s internal components, reducing their performance and lifespan.


For the clean, odor-free mist, it includes a microporous cartridge that catches microorganisms, thus increasing the safety of your home. For the best results, it is recommended to change the filter every 4 to 6 months.

When it comes to choosing the best warm mist humidifier, some specifications are worth to be considered. Depending on the space you are going to use this appliance, you may want to pay attention to its mist output, area of coverage, maximum run period, or integrated smart functions.
