Please follow the in-app   instructions to set up your voice assistant.   Note: You must create your own VeSync account   to access voice assistants.   Figure 2.1   7 USING YOUR PURIFIER (CONT.)   Sleep Mode   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.   Sleep 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 after   3 seconds if no other buttons are tapped.   • • Auto Mode does not use the turbo   fan speed.   Note:   The VeSync app also supports   additional auto modes: Quiet Auto   Mode and Efficient Auto Mode   (see page 10).   • • When the display is turned off, tap any   button (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).   PM2.5 Display   The PM2.5 value on the display shows the   amount of airborne particles (µg) that are   detected per 1 cubic meter (m³) of air volume.   Auto Mode   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.   Auto Mode uses AirSight™ 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.   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.   Air Quality Indicator Chart   Indicator Color   Blue   Air Quality   Auto Mode Fan Speed   PM 2.5 Range   0–35 ug/m3   36–75 ug/m3   76–115 ug/m3   > 115 ug/m3   Very Good   Good   Sleep Mode   Low   Green   Orange   Red   Moderate   Bad   Medium   High   8 USING YOUR PURIFIER (CONT.)   Timer   Display Off   You can set a timer for 1–12 hours.   This turns off the display lights on the air   purifier, including button lights and indicator   lights (except the Check Filter Indicator).   1.

The laser dust sensor will still detect   the surrounding air quality and give you   updates in the VeSync app.   • 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.   Memory Function   When 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: 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.   Note: The air purifier will remember the last   timer setting chosen (1–12 hours), but it will   not automatically resume the timer. You will   need to restart the timer after the air purifier   is turned back on.   Schedules   Create and customize schedules for   your air purifier to match your routines.   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.   Timer Function   • • Set a timer between 1–24 hours.   Remote Control   Easily view the exact time remaining   on a timer.   • Change any air purifier settings   through the app, even while   Display Lock is on.   Filter Replacement Info   • Keep tabs on the remaining filter life   by checking the filter life percentage   in the app.   Air Quality Updates   • • View real-time PM2.5 updates in the app.   See your air quality history for the   previous week.   • Shop for replacement filters.   10   ABOUT THE FILTER   The air purifier uses a 3-stage filtration   system to purify air.   A B C C. Custom High-Efficiency Activated   A. Pre-Filter   Carbon Filter   • Captures large particles such as   dust, lint, fibers, hair, and pet fur.   • • Physically adsorbs smoke, odors,   and fumes.   • Maximizes the filter’s life by   protecting it.   Customized using Levoit’s exclusive   ARC Formula™ to be especially   effective for cooking smells and pet   odors in a multi-pet household.   B. H13 True HEPA Filter   • Captures at least 99.97% of airborne   particles 0.3 microns (µm) in size.   • • The ARC Formula extends the life of   the filter by chemically decomposing   molecules trapped within the   Activated Carbon Filter, which   prevents oversaturation and second-   hand pollution.   • Traps small particles such as fine   dust, smoke particles, and allergens   such as pollen and pet dander.   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   ABOUT THE FILTER (CONT.)   Clean Air Delivery Rate   Humidity   This air purifier has a Clean Air Delivery Rate of   260 cubic feet per minute (CFM), or 442 m³/h.   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.   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.   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   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.   Air Change Per Hour   The 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.   12   CARE & MAINTENANCE   Cleaning the Smart Air Purifier   Cleaning the Filter   • • Unplug before cleaning.   The outer pre-filter should be cleaned every   2–4 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.   Wipe the outside of the air purifier   with a soft, dry cloth.
