PM2.5 monitoring: real-time understanding of air quality
The Wall mounted 300 CADR air fresh ventilation device is equipped with a PM2.5 digital display function, which can accurately detect the PM2.5 concentration in the indoor air and provide real-time feedback to the user through a digital display. PM2.5 concentration is one of the important indicators for measuring air quality. When the PM2.5 concentration in the indoor air is high, the device will automatically increase the wind speed for air purification, help reduce harmful particles in the air, and restore a fresh air environment.

Efficiently purify PM2.5 to ensure fresh indoor air
PM2.5, as one of the main components of air pollution, comes from external air pollution sources and indoor activities, such as car exhaust, smoke from combustion, kitchen fumes, etc. The Wall mounted 300 CADR air fresh ventilation device uses advanced multi-layer filtration technology to efficiently filter PM2.5 particles in the air. The device is equipped with a HEPA high-efficiency filter element inside, which can filter out 99.97% of tiny particles, including PM2.5.

The working principle of the HEPA filter is to capture fine particles in the air through an efficient fiber mesh to prevent them from entering the respiratory tract. Combined with the device's 300 CADR value (clean air delivery ratio), this device can effectively purify indoor air in a short period of time, reduce PM2.5 concentration to the level, and ensure that the indoor air always remains fresh and healthy.

Intelligent adjustment, automatic optimization of air quality
In addition to real-time monitoring and efficient purification of PM2.5, the Wall mounted 300 CADR air fresh ventilation device also has an intelligent adjustment function. Through the built-in sensor, the device can automatically adjust the wind speed according to the detected PM2.5 concentration. When the PM2.5 concentration is high, the device will automatically enter the high wind speed mode to increase air circulation and improve air purification efficiency; when the air quality improves, the device will automatically reduce the wind speed to maintain quiet and energy-saving operation.

Multiple display functions, real-time feedback of indoor air changes
The Wall mounted 300 CADR air fresh ventilation device can not only monitor PM2.5 concentration, but also display multiple air quality indicators such as CO2 concentration, negative ion concentration, temperature and humidity. Through the display of these real-time data, users can fully understand the changing trends of indoor air quality and take timely adjustment measures to ensure that the air quality is always in an ideal state.

Filter life reminder to ensure continuous monitoring and purification effect
The Wall mounted 300 CADR air fresh ventilation device is equipped with a filter life reminder function. When the filter element needs to be replaced, the device will automatically remind the user to perform maintenance to ensure that the device can continue to work efficiently. Regular replacement of the filter element not only helps to improve air purification efficiency, but also ensures the accuracy of the PM2.5 monitoring function.
