The filter of the humidifier is mainly used to filter impurities in the water, reduce scale and bacteria, ensure the normal operation of the humidifier, and make the sprayed water mist cleaner. The specific functions are as follows:

1. Filter impurities in water

Tap water or ordinary water may contain minerals (such as calcium, magnesium), tiny particles or sediments. The filter can block these impurities, prevent them from being atomized and floating into the air, and reduce irritation to the respiratory tract after inhalation.

2. Reduce scale accumulation

If the water is hard (for example, there is white scale at the bottom of the kettle after boiling water), the filter can absorb some minerals to prevent them from scaling inside the humidifier (such as ultrasonic sheets or heating tubes), thus extending the life of the machine.

3. Inhibit bacteria and odors

Some filters contain antibacterial ingredients (such as silver ions), which can slow down the growth of bacteria and mold, and prevent mold or odor inside the humidifier. However, the filter cannot completely kill bacteria, so you still need to clean the water tank and change the water regularly.

4. Maintain humidification effect

If the filter is too dirty or clogged with scale, the mist output of the humidifier will decrease, affecting the humidification efficiency. Regularly cleaning or replacing the filter can make the humidifier work more stably.

Issues to note

• Clean or replace regularly: The filter will accumulate scale and bacteria after long-term use. It is recommended to clean it according to the instructions (white vinegar or citric acid can be used for descaling) or replace it.

• Water quality affects the life of the filter: If the water quality is poor (such as hard water), the filter will get dirty faster. It is recommended to use it with purified water or softened water.

• Some humidifiers do not have filters: For example, evaporative humidifiers may use other technologies (such as UV sterilization) to purify water, but the water tank should also be cleaned regularly.

Summary: The function of the filter is to make the water mist sprayed by the humidifier cleaner and reduce scale and bacterial problems, but the key is to maintain it regularly to avoid secondary pollution.
