Xiaomi Smart Humidifier 2 FAQ

Question

Accepted Answer

Overview
Q1：What is a humidifier?
A：A humidifier is a household appliance that can increase the humidity of a room. A humidifier can humidify a designated room, or it can be connected to a boiler or central air conditioning system to humidify the entire building.
According to the theory of heat and moisture exchange, humidifiers are divided into the following two types in practical engineering:
1. Iso-enthalpy humidifier: that is to use water to absorb the sensible heat of air for evaporative humidification, and its change on the enthalpy and wet map is an approximate iso-enthalpy process. (humidity increases, temperature drops), ultrasonic humidifiers belong to isenthalpic humidification.
2. Isothermal humidifier: that is, the use of heat energy to convert liquid water into steam and mix with air for humidification, and its changes in enthalpy and hygrogram are approximate isothermal processes. (Humidity increases, temperature does not change).
Humidifiers can be divided into three major categories: industrial humidifiers, commercial humidifiers and household humidifiers.
 
Q2: Are humidifiers harmful to the human body?
A: The risk of humidifiers is manifested in the humidity content in the air after use. Excessive humidity will affect the body. Indoor air humidification can be done by sprinkling water, placing water basins, etc., but the most convenient way is to use a humidifier.
When the humidifier is used, it should be cleaned regularly, otherwise the microorganisms such as mold in the humidifier will enter the air with the vapor and then enter the respiratory tract of the person, and it is easy to suffer from humidifier pneumonia. In addition, the humidity of the air is not as high as possible. In winter, the human body feels more comfortable humidity is about 50%. If the air humidity is too high, people will feel chest tightness and difficulty breathing, so it is better to humidify moderately.
 
Q3: What are the benefits of humidifiers? 
A: For your reference, here are the benefits of humidifiers:
1. Proper humidification in the living room can effectively prevent the wooden furniture from being deformed and the walls just painted from getting cracked.
2. Turn on the humidifier when cutting onions to avoid tears.
3. Reduce indoor dust and static electricity.

Q7: What to do if using the Xiaomi Smart Humidifier 2 at the same time as an air purifier and a PM2.5 detector causes both devices to display abnormal PM2.5 readings? 
A: Since the Xiaomi Smart Humidifier 2 will break up water into relatively small water mist particles, the diameter of water droplets is similar to that of various air dusts, such as PM2.5, but it is the same for the particle sensor of the Xiaomi Air Purifier, which mistakes smaller water droplet particles for airborne dust.
Therefore, in automatic mode, when the purifier detects high PM2.5 levels in the air, it will run at a higher power level, which is normal. The PM2.5 detector will also increase the PM2.5 reading, which is normal. Happening.
It is recommended to use the air purifier and the humidifier as differently as possible at the same time. If they need to be used at the same time, try to keep the air purifier, PM2.5 detector, and humidifier farther apart or out of the same room.

2. Check whether the router is correctly connected to the external network, and whether the webpage opens smoothly on the mobile phone or PC connected to the Wi-Fi.
3. Check if the distance between the router and the humidifier is too far (beyond 5 meters) or if there is a partition wall in the middle. If so, you can try moving the router to within 1~2 meters of the humidifier and reconnecting it.
4. You can use your mobile phone as a Wi-Fi hotspot and connect it to another mobile phone. If they can be connected properly, refer to (3) to perform troubleshooting. If the equipment fails to connect with the hotspot, you can contact the after-sales service center.
5. Check whether the router is connected to many devices, which can cause the network to jam or the router to become unresponsive. You can restart the router and try again.
6. The current humidifier is incompatible with EAP 802.1x networks, 5 GHz signal networks, or public Wi-Fi networks that require web authentication. You need to swap the network and try to connect to it.
7. The connection failure can also be attributable to the mobile phone. It is recommended to use another mobile phone to try the link, or download the Xiaomi Home App again. Try upgrading to the latest version.
8. When you need to reconnect the humidifier, it is recommended to reset the humidifier’s Wi-Fi and reconnect it. The humidifier can be reset using the method below: Press and hold the power button for 7 seconds. When the Wi-Fi indicator flashes orange, it has been reset successfully. After it is connected, open the App to reconnect the device with the Wi-Fi and bind it.

A: If you find water in the base after lifting the water tank and are worried about electrical leakage, please rest assured that this is normal. The humidifier is easy to use.
The water in the tank first flows into the base tank, then through the sterilization zone, atomizer, and other components to complete the water sterilization process. Finally, the atomizer atomizes the water into droplets, which are then sprayed out through the outlet to achieve humidification.
 
Q10: Is it normal that there is water in the Xiaomi Smart Humidifier 2 after opening the new device?
A: The reason why the Xiaomi Smart Humidifier 2 has a small amount of water droplets is that the product has been tested before leaving the factory. It is normal to see a small number of water droplets inside the device, and they will not affect the product's hygiene or safety performance.

Q12: Why is the humidity displayed on the Xiaomi Home App of the Xiaomi Smart Humidifier 2 inconsistent with that on the hygrometer?
A: The Xiaomi Smart Humidifier 2 is designed with humidity detection, and the sensor is located in the base.
If different humidity values are displayed on various devices, you can make judgments based on the points below:
1. The humidity measured by a hygrometer can vary widely depending on its location within the indoor environment. Therefore, the hygrometer can be placed near the humidifier to measure humidity for 10 minutes, until the value stabilizes.
2. For different products, the humidity detection method and working method may differ slightly, resulting in slight differences in the values reported by various measuring instruments. Each product undergoes strict quality inspection before delivery and also includes a product performance certification report issued by the national certification agency.
