The core function and principle of the sleep mode
Sleep mode is a special feature of the Medical Grade New Model 1200 CADR Air Purifier. In this mode, the air purifier operates at low wind speed and low noise to ensure that users are not disturbed during sleep. The core goal of this mode is to optimize the air purification effect while reducing the operating noise to create a quiet indoor environment.

1. Wind speed adjustment and noise control
In sleep mode, the air purifier automatically adjusts to the lowest wind speed (F1), which can not only continue to purify the air without generating obvious noise. When running at low wind speed, the air flow is relatively gentle, and the working sound of the equipment is greatly reduced, so that users can hardly feel the existence of the equipment when resting. For people who need a highly quiet environment, especially children and the elderly, this function provides vital help to ensure that they get undisturbed sleep at night.

In addition, the fan design under low-speed operation has also been finely optimized to reduce the vibration and noise that may be generated when the fan is running, which further improves the quiet effect of the air purifier. Even if the device is running for a long time, users will not be disturbed by uncomfortable noise and can enjoy quiet and fresh indoor air.

2. Intelligent adjustment and air quality maintenance
Although the device runs at a low speed in sleep mode, the Medical Grade New Model 1200 CADR Air Purifier still has a strong air purification ability. Its built-in intelligent purification mode can monitor the indoor air quality in real time and automatically adjust the operation mode. In sleep mode, when the air quality changes, the device can still adjust the wind speed or turn on other functions (such as UV light sterilization) to maintain continuous improvement of air quality.

3. Energy saving and extended service life
In sleep mode, the low-speed operation of the air purifier not only reduces noise, but also effectively reduces the energy consumption of the device. By reducing the wind speed, the air purifier can operate in a more energy-saving way, ensuring that the device does not waste energy and maintains good air quality when used at night or for a long time. In addition, long-term low-speed operation helps reduce wear and tear on the equipment and extend the service life of the air purifier.

The relationship between sleep mode and healthy sleep environment
Sleep quality directly affects physical health and mental state, and air quality is one of the important factors affecting sleep quality. The sleep mode of the Medical Grade New Model 1200 CADR Air Purifier creates a suitable sleeping environment for users by reducing noise and continuously purifying the air. Studies have shown that pollutants such as PM2.5, allergens, bacteria and viruses in the air can cause problems such as poor breathing and allergic reactions, thus affecting the quality of sleep. This air purifier can effectively filter these harmful substances, ensuring fresh air while reducing environmental noise, providing better protection for sleep.

1. Reduce harmful substances in the air
In sleep mode, the Medical Grade New Model 1200 CADR Air Purifier still effectively filters harmful substances in the air, including PM2.5, formaldehyde, smoke, allergens, etc. Continuous air purification not only provides users with fresh air, but also reduces the concentration of harmful substances in the room, making breathing smoother and helping deep sleep. In addition, the built-in UV light sterilization function of the device can further remove bacteria and viruses in the air, providing users with a healthier sleeping environment.

2. Improve comfort
The air purifier in sleep mode runs more smoothly, does not make disturbing sounds or generate excessive wind, and maintains appropriate air flow and humidity. This low-noise, stable working state allows users to enjoy a more comfortable breathing experience during sleep and helps improve sleep quality.
