What is CADR value?
CADR (Clean Air Delivery Rate) is an important indicator of air purification equipment performance, which measures the efficiency of the equipment in purifying the air. The higher the CADR value, the faster and more efficiently the equipment can clean harmful substances in the air. The 300 CADR value of the Wall mounted 300 CADR air fresh ventilation device means that it can purify 300 cubic meters of air per hour. Compared with ordinary air purifiers, it has a stronger air processing capacity and is suitable for homes, offices and commercial spaces.

Efficiently purify PM2.5 and keep the air fresh
PM2.5 (fine particles with a diameter of less than or equal to 2.5 microns) is one of the dangerous substances in air pollution. Long-term exposure to high concentrations of PM2.5 can cause respiratory and cardiovascular diseases. The Wall mounted 300 CADR air fresh ventilation device can efficiently remove PM2.5 particles from the air.

Remove formaldehyde and volatile organic compounds (VOCs)
Formaldehyde and volatile organic compounds (VOCs) are common pollutants in the home environment, especially in newly renovated houses, the concentration of formaldehyde in indoor air may exceed the safety standard. The Wall mounted 300 CADR air fresh ventilation device has a built-in high-efficiency filter that can effectively absorb harmful substances such as formaldehyde, benzene, TVOC, quickly purify toxic gases in the air, and reduce the harm of indoor pollutants.

High-efficiency filtration system, fresh every inch of air
Wall mounted 300 CADR air fresh ventilation device adopts an advanced multi-layer filtration system, including a pre-filter, HEPA high-efficiency filter element, activated carbon filter element, etc. The pre-filter can intercept large particles of dust and impurities to prevent the filter element from clogging prematurely; the HEPA high-efficiency filter element can filter out 99.97% of tiny particles in the air, such as PM2.5, pollen, bacteria, etc.; and the activated carbon filter element specifically absorbs harmful gases and odors in the air, such as formaldehyde, carbon dioxide, etc.

Intelligent monitoring, real-time control of air quality
The Wall mounted 300 CADR air fresh ventilation device has multiple built-in intelligent sensors that can monitor the concentration of pollutants in the indoor air in real time and feed the data back to the device display. Through the functions of PM2.5 concentration display, CO2 concentration display, negative ion concentration display, etc., users can intuitively understand the changes in air quality. When the device detects a high concentration of air pollutants, it will automatically adjust the wind speed and operation mode to ensure that the air quality is always maintained in an ideal state.

Automatic mode, worry-free and labor-saving
The automatic mode of the Wall mounted 300 CADR air fresh ventilation device is a highlight. In automatic mode, the device can automatically adjust the working state according to the real-time detected air quality, including wind speed, air circulation mode, etc. Whether the PM2.5 concentration is too high or the carbon dioxide concentration exceeds the standard, the device can automatically adjust the operating parameters according to the preset standards to maintain the air purification effect.

Filter life reminder to ensure continuous purification effect
In order to ensure the efficient operation of the equipment, the Wall mounted 300 CADR air fresh ventilation device is equipped with a filter life reminder function. When the filter element is close to its service life, the device will automatically remind the user to replace or clean it. Regularly replacing filters can not only ensure the purification effect of the equipment, but also extend the service life of the equipment.
