USING YOUR SMART AIR PURIFIER

Note: Using the VeSync app allows you to control your air purifier remotely and access additional functions and features.

1. Plug in and tap ~ to turn on the air purifier. The fan will start on low speed.
   [Figure 2.1]

2.  Optionally, tap ,%’ to change fan speed between low, medium, high, and turbo.
   Note:
   The fan speed indicators will light up when active. 1 indicator will light up for low, 2 for medium, 3 for high, and 4 for turbo.
   Turbo speed is the loudest, but cleans air the quickest.
   For best results, or to address a specific air quality issue such os smoke, run the air purifier at turbo speed for 15-20
   minutes before using a lower speed.
   To effectively clean air, keep windows and doors closed while the air purifier
   is on.

3. Tap ~ to turn off the air purifier.

Sleep Mode
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.

Note:

• 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).

Auto Mode
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.

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 opp also supports additional auto modes: Quiet Auto Mode and Efficient Auto Mode (see page 10).

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.

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.

Timer
You can set a timer for 1-12 hours.

1. Tap  The display will switch from showing the PM2.5 reading to the time you’ve selected.

2. Tap  repeatedly to select a time in 1-hour increments. If you don’t touch any buttons for 5 seconds, the display will
   switch to showing the PM2.5 reading and the timer will start automatically.
   Note: Press and hold for 2 seconds to cycle through timer options automatically in 1-hour increments.

3. The timer will count down from your selected time.
   Note:
   While a timer is active, tapping will show the remaining time, rounded up to the nearest hour. Tap <::) again within
   5 seconds to add more time in 1-hour increments.
   You can see the exact remaining time in the VeSync app.

4. When the timer is finished, the air purifier will turn off.

5. To cancel a timer, tap repeatedly until the display reads “–H”.

Standby Mode
The 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 opp.

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: 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.

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 PM2.5 updates in the app.
• See your air quality history for the previous week.

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.

Filter Replacement Info

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

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.
  • 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 Fainter
  • Physically adsorbs smoke, odors, and fumes.
  • Customized using Levoit’s exclusive ARC Formula™ 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 second-hand pollution.
  • Filters compounds such as formaldehyde, benzene, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).

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

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.

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 can change air 5 per up to 403 ft2 / 37 m2 . This is measured at ACH 5. The air purifier is effective for larger rooms, but air purification will take longer, with fewer air changes per hour. For example, the
air purifier’s effective range is 990 ft2 / 92 m2 based on 2 ACH, or purifying the air in the room 2 times per hour.

Note: To effectively clean air, keep windows and doors closed while the air purifier is on.

Humidity
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 mouldy.
Note: Water or moisture will allow mold to grow. To solve a mold problem, get rid of the source of the moisture an 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.

CARE & MAINTENANCE

Cleaning the Smart Air Purifier

• 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 Indicator

will 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 •lul• 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.

Cleaning the Filter
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.

When Should I Replace the Filter?
The filter should be replaced every 12 months. You may need to replace your filter earlier or later depending on how often you
use your air purifier. Using your air purifier in an environment with relatively high pollution may mean you will need to replace the filter more often, even if •lul• is off. You may need to replace your filter if you notice:

• Increased noise when the air purifier is on
• Decreased airflow
• Unusual odors
• A visibly clogged filter

Note:

• To maintain the performance of your air purifier, only use official Levoit filters.
• Remember to reset •lul• after changing the filter (see page 13).

Cleaning the AirSight Plus Laser Dust Sensor
The AirSight Plus Laser Dust Sensor can be blocked by dust, which affects the sensor’s accuracy. Clean the sensor every 3 months. Using your air purifier in an environment with more dust may mean you will need to clean the sensor more often.

1. Unplug the air purifier.
2. Place the end of a vacuum cleaner over the sensor openings. [Figure 3.3]
3. Turn the vacuum on for at least 10 seconds to clean out dust.

Replacing the Filter

1. Unplug the air purifier. Flip the air purifier over or turn it on its side. Remove the filter cover (see Getting Started, page 6).
2. Remove the old filter.
3. Clean out any remaining dust or hair inside the air purifier using a vacuum hose. Do not use water or liquids to clean the air purifier. [Figure 3.2]
4. Unwrap the new filter and place it into the housing (see Getting Started, page 6).
5. Replace the cover. Plug in the air purifier.
6. Reset the Check Filter Indicator (see page 13).

Storage
If not using the air purifier for an extended period of time, wrap both the air purifier and the filter in plastic packaging and store in a dry place to avoid moisture damage.
