AQI (AIR QUALITY INDEX)
AQI, or Air Quality Index, is a measurement of your overall air quality represented in a value. Generally, the lower the number, the better your air quality. Your air purifier’s AirSight Pro® smart sensor reads the concentration of particles and TVOCs in the air and uses an algorithm to accurately measure AQI.
AQI calculation is based on:

• The concentration of particles detected in the air, including PM1.0, PM2.5, and PM10*.
• The concentration of TVOCs (Total Volatile Organic Compounds) detected in the air, such as fumes from solvents, paints, and chemicals.
• The change in detected particles and TVOCs during purification.

*Refers to particulate matter (PM) less than or equal to 1, 2.5, or 10 microns (µm) in size (measured by the diameter of the particle). For example, PM2.5 refers to particulate matter that is 2.5 microns or smaller.
The air quality indicators will change colors according to your air quality:

AQI Value	Indicator Color	Air Quality
0–50	Blue	Very Good
51–100	Green	Good
101–150	Orange	Moderate
≥151	Red	Bad

AUTO MODE
Auto Mode uses AirSight® Pro, the smart sensor inside your air purifier, to adjust the fan speed automatically based on air quality. For example, if the air quality is bad, the fan will automatically adjust to level 4.

• Tap until the display shows “AU” (Auto Mode).

VeSync App Functions

The VeSync app allows you to access additional smart air purifier functions, including those listed below. As the app develops, more features may become available.
Remote Control

• Change any air purifier settings through the app, even while Display Lock is on.

Air Quality Updates

• View real-time air quality updates in the app.
• See your air quality history for the previous 4 weeks.

Schedules

• Create and customize schedules for your air purifier to match your routines.

Filter Replacement Info

• Keep tabs on the remaining filter life by checking the filter life percentage  in the app.
• Shop for replacement filters.

Auto Mode

• Access additional auto modes: Quiet Auto Mode and Efficient Auto Mode.
• Quiet Auto Mode uses medium fan speed (level 3) instead of the highest or turbo fan speeds, even when the air quality is poor, to avoid making too much noise.
• Efficient Auto Mode lets you choose the size of the area you want to purify. The air purifier will use the highest fan speed to clean the air for a designated amount of time. This time is based on 1 ACH and the size of the room, meaning how long it takes for the air purifier to clean all the air in your room one time, regardless of the air quality. After this, the mode will adjust the fan speed according to the actual detected air quality in the room.

Note: Efficient Auto Mode is useful for purifying odors from the air. The air purifier’s sensor can not detect smells. Efficient Auto Mode does not rely on the sensor, but the room size instead.

About the Filter

The air purifier uses a 3-stage filtration system to purify air. A. Pre-Filter

• Captures large particles such as dust, lint, fibers, hair, and pet fur.

B. HEPA Filter

• Traps at least 99.97% of airborne particles 0.1–0.3 microns in size.
• Traps 99.9% of airborne particles 0.01 microns in size.

C. High-Efficiency Activated Carbon Filter

• Physically adsorbs smoke, odors, and fumes.
• Filters compounds such as, benzene, ammonia, sulfur dioxide, nitrogen dioxide, and volatile organic compounds (VOCs).

COVID-19 DISCLAIMER
According to the CDC, portable HEPA filtration units that combine a HEPA filter with a powered fan system are effective at cleaning air within spaces to reduce the concentration of airborne particulates, including SARS-CoV-2 (COVID-19) viral particles.
