To combat the cold, air conditioning and heating have become common heating methods, which can increase indoor moisture loss and make the indoor air dry.

According to a street survey, more than half of the respondents could feel the discomfort caused by dry air.

Dry air prevents the widely distributed cilia on the surface of the respiratory tract from eliminating bacteria or dust, which can lead to respiratory illness.

At the same time, too hot and dry air will accelerate the evaporation of skin moisture, wrinkles, and accelerated aging.

It's healthier to use a humidifier this way：

1. Choose a humidifier with a sterilization function

Common humidifiers on the market are divided into two main categories, namely, evaporative humidifiers and ultrasonic atomizing humidifiers.

Ultrasonic atomization humidifier, through the piezoelectric ceramic piece of high-frequency alternating current, produces small water droplets to achieve the role of wet air.

Evaporative humidification through the "let the water directly evaporate into water vapor" way to complete the humidification, carrying less impurities.

Advanced humidifiers have been equipped with more reliable sterilization antibacterial technology, such as ultraviolet sterilization, silver ion antibacterial, pasteurization, and so on.

Ultraviolet sterilization technologies can make the bacteria no longer have the ability to reproduce, compared to the role of stronger.

2. Humidifier water quality in the tank is particularly critical

As most consumers still tend to buy relatively low-priced ultrasonic humidifiers, this type of humidifier on the water quality requirements are higher.

It is best to use pure water, you can also use filtered water or boiled and cooled water.

Chlorine molecules and microorganisms in tap water have the potential to enter into the air with the water mist and cause contamination.

Regardless of the type of humidifier, do not add vinegar, disinfectant, or essential oils to the water, which may trigger asthma and other respiratory diseases.

3. Regularly clean the humidifier

Experiments show that placed a week of pure water and tap water, both in the cup wall appeared to be dirt, tap water, and even water quality yellowing.

It can be seen, that the humidifier must be used in the process of regular replacement of clean water and the humidifier itself for cleaning.

4. Real-time monitoring of indoor air humidity

The human body is comfortable with air humidity between 40% -70%.

Air humidity is too low and too high humidity will help airborne bacteria breed, and cause discomfort, but also may further affect people's health.

It is therefore advisable to use humidifiers along with humidity monitoring devices.
