Air Quality Indicator Chart
Indicator Colour	Air Quality	Auto Mode Fan Speed
Blue	Very Good	Sleep Mode
Green	Good	Low
Orange	Moderate	Medium
Red	Bad	High

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 colour 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.

PM2.5 Display

The PM2.5 value on the display shows the amount of airborne particles (µg) that are detected per 1 cubic metre (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 mould.
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.

Tap . The display will switch from showing the PM2.5 reading to the time you’ve selected.
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.
The timer will count down from your selected time.
Note:

- You can see the exact remaining time in the VeSync app.
When the timer is finished, the air purifier will turn off.
To cancel a timer, tap repeatedly until the display reads “–H”.

Note:

You can change the fan speed at any time while the timer is on.
The timer will restart if the time is changed.
The air purifier will remember the last timer setting while turned off, but the timer will be cancelled and need to be restarted.

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, fibres, hair, and pet fur.
Maximises 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 mould spores, fine dust, smoke particles, bacteria and viruses*, and allergens such as pollen, dust mites, and pet dander.
C. Custom High-Efficiency Activated Carbon Filter
Physically adsorbs smoke, odours, and fumes.
Customised using the ARC formula to be especially effective for cooking smells and pet odours in a multi-pet household.
Filters compounds such as formaldehyde, benzene, ammonia, hydrogen sulphide, and volatile organic compounds (VOCs).

The H13 True HEPA Filter can remove most viruses and bacteria from the air, but cannot fully remove them from your environment. Air purifiers cannot prevent an infected person from spreading an infection, and cannot remove bacteria and viruses from surfaces. Please use this air purifier together with other precautions.

Clean Air Delivery Rate
This air purifier has a Clean Air Delivery Rate of 400 m³/h or 235 cubic feet per minute (CFM).
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 2.4 m / 8 ft ceilings. For smaller rooms, the air change per hour will increase. This air purifier has an air change per hour of 2, which means it can change air 2 times per hour at the max speed in a single, closed room up to 83 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.

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 mould to grow. To solve a mould problem, get rid of the source of the moisture and clean up the mould. Air purifiers cannot solve an existing mould problem, and can only remove airborne mould spores and reduce odours.

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 and 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 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. [Figure 3.1] Do not clean the filter with water or other liquids.

Filter	When to Clean	How to Clean	When to Replace
Pre-Filter	Every 2–4 weeks	Use a soft brush or vacuum hose [Figure 3.1]	12 months
True HEPA & Activated Carbon Filter	Do not clean		12 months

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 is off.
You may need to replace your filter if you notice:

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

Note:

To maintain the performance of your air purifier, only use official Levoit filters. To buy replacement filters, go to Amazon and search B08SQQK6K7.
Remember to reset after changing the filter.

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.

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

Replacing the Filter

Unplug the air purifier. Flip the air purifier over or turn it on its side. Remove the filter cover (see Getting Started, page 6).
Remove the old filter.
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]
Unwrap the new filter and place it into the housing (see Getting Started, page 6).
Replace the cover. Plug in the air purifier.
Reset the Check Filter Indicator.

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.
