USING YOUR PURIFIER (CONT.)Sleep ModeSleep Mode operates quietly by using a fan speed lower than low speed. 1. Tap to turn Sleep Mode on/off. 2. Sleep Mode will turn off the display after3 seconds if no other buttons are tapped.Note: · When the display is turned off, tap anybutton (except ) to turn the display back on. If you don’t tap another button, the display will turn off again after 3 seconds. · The Check Filter Indicator will still turn on and stay on if it’s time to check your filter (see page 13).Auto ModeAuto Mode uses AirSightTM Plus, a smart laser dust sensor inside the air purifier, to adjust the fan speed automatically based on air quality. For example, if the air quality is bad, the fan will automatically be set to high speed.

Note:· The air purifier will take 5 seconds to detect the air quality each time it is turned on. During this time, the air quality indicator rings will be blue. After 5 seconds, the air quality indicator rings will change color based on the detected air quality.· Auto Mode does not use the turbo fan speed.· The VeSync app also supports additional auto modes: Quiet Auto Mode and Efficient Auto Mode (see page 10).PM2.5 DisplayThe PM2.5 value on the display shows the amount of airborne particles (µg) that are detected per 1 cubic meter (m³) of air volume.PM2.5 refers to particulate matter (PM) that is less than or equal to 2.5 microns (µm) in diameter. These particles, also known as “fine particles”, are so small that they can only be detected with an electron microscope, and they stay in the air longer than heavier particles such as dust and mold.Your air purifier’s AirSight Plus Laser Dust Sensor detects the amount of PM2.5 particles that are in a given space (µg/m³). Generally, the lower the number, the better your air quality. A number above 115 indicates that there is an unhealthy amount of fine particles in the air.

Standby ModeThe air purifier is in Standby Mode when it is turned off, but plugged in.Note: Display Lock can be used while the air purifier is in Standby Mode to keep the air purifier from being turned back on. The laser dust sensor will still detect the surrounding air quality and give you updates in the VeSync app.Memory FunctionWhen the air purifier is plugged in and turned off, it will remember its previous fan speed, Sleep Mode, Auto Mode, Display Lock, and Display Off settings. When the air purifier is unplugged and turned off, it will only remember its previous fan speed, Sleep Mode, and Auto Mode.Note: The air purifier will remember the last timer setting chosen (1­12 hours), but it will not automatically resume the timer. You will need to restart the timer after the air purifier is turned back on.

Auto Mode· Access additional Auto Modes: Quiet Auto Mode and Efficient Auto Mode.· Quiet Auto Mode uses medium fan speed instead of the high 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 (turbo) to clean the air for a designated amount of time. This time is based on ACH 1 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 only detect particles in the air, not smells. Efficient Auto Mode does not rely on the sensor, but the room size instead.

A B O U T T H E F I LT E RThe air purifier uses a 3-stage filtration system to purify air.A



A. Pre-Filter· Captures large particles such as dust, lint, fibers, hair, and pet fur.· Maximizes the filter’s life by protecting it.B. H13 True HEPA Filter· Captures at least 99.97% of airborne particles 0.3 microns (µm) in size.· Traps small particles such as fine dust, smoke particles, and allergens such as pollen and pet dander.

C. Custom High-Efficiency Activated Carbon Filter· Physically adsorbs smoke, odors, and fumes.· Customized using Levoit’s exclusive ARC FormulaTM to be especially effective for cooking smells and pet odors in a multi-pet household.· The ARC Formula extends the life of the filter by chemically decomposing molecules trapped within the Activated Carbon Filter, which prevents oversaturation and secondhand pollution.· Filters compounds such as formaldehyde, benzene, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).

Note: Levoit air purifiers filter airborne particles 0.3 microns in size. Arovast Corporation makes no claims that this air purifier helps reduce the COVID-19 virus.11


Clean Air Delivery Rate


This air purifier has a Clean Air Delivery Rate of 260 cubic feet per minute (CFM), or 442 m³/h.Clean Air Delivery Rate (CADR) measures the efficiency of an air purifier by indicating the volume of clean air that an air purifier produces per minute. This is based on removal of dust, pollen, and smoke, which are the 3 most common indoor air pollutants. The higher the CADR, the more particles the air purifier will remove and the larger the area it can clean. The rating is measured at the air purifier’s highest speed.

Moisture may damage the filter. This air purifier should be used in an area with a humidity level below 85% RH. If you use the air purifier in excessively humid areas, the surface of the filter may become moldy.Note: Water or moisture will allow mold to grow. To solve a mold problem, get rid of the source of the moisture and clean up the mold.Essential Oils

Air Change Per HourThe air change rate is how many times all of the air in a room can be purified (or “changed”) by the air purifier in 1 hour. Air changes per hour (ACH) are calculated with the recommended room size assuming 8 ft / 2.4 m ceilings. For smaller rooms, the air change per hour will increase. This air purifier has an air change per hour of 5, which means it can change air 5 times per hour at the max speed in a single, closed room up to 403 ft² / 37 m². The air purifier is effective for larger rooms, but air purification will take longer, with fewer air changes per hour.Note: To effectively clean air, keep windows and doors closed while the air purifier is on.

Do not add essential oils to the air purifier or filter. The filter will become damaged by the oil and will eventually release an unpleasant smell. Do not use diffusers near the air purifier.



Cleaning the Smart Air Purifier

Cleaning the Filter

· Unplug before cleaning.· Wipe the outside of the air purifier with a soft, dry cloth. If necessary, wipe the housing with a damp cloth, then immediately dry.· Vacuum the inside of the air purifier.· Do not clean with abrasive chemicals or flammable cleaning agents.Check Filter Indicatorwill light up as a reminder to check the filter. Depending on how often you use the air purifier, the indicator should turn on at about 12 months. You may not need to change your filter yet, but you should check it when turns on.When your air purifier is set up with the VeSync app, you can also check the app to see your remaining filter life. You will also receive a notification from VeSync when it’s time to check your filter.The VeSync app uses a scientific algorithm to determine your filter life based on air quality, amount of use, and other factors. The filter life percentage is based on 12 hours of daily use.

The outer pre-filter should be cleaned every 2­4 weeks to increase efficiency and extend the life of your filter. Clean the pre-filter using a soft brush or vacuum hose to remove hair, dust, and large particles. Do not clean the filter with water or other liquids.
