Air Quality Updates

View real-time air quality updates in the app.

See your air quality history for the previous 4 weeks.

Pet Mode

• Pet Mode is efficient at filtering allergens from the air while conserving energy.
• When Pet Mode is on, the air purifier runs for 15 minutes at high speed (3 indicator lights), then 60 minutes at medium speed (2 indicators), and cycles between the two fan speeds. The corresponding fan speed indicators and on the air purifier's display will light up.
• When Pet Mode is on, and the light sensor detects the room is dark, the display will turn off and limit Pet Mode to medium fan speed (2 indicators), to avoid making too much noise. When the light sensor detects that the room is lit again, Pet Mode will no longer be limited, and the air purifier will run at medium fan speed (2 indicators) for 30 minutes, then run at high (3 indicators) for 15 minutes. After this, the normal Pet Mode cycle will start (15 minutes at high speed, then 60 minutes at medium speed).
• To turn off Pet Mode, tap Auto Mode, Sleep Mode, or select a fan speed on the air purifier's display or in the VeSync app.

Note:

• The corresponding fan speed indicators will light up depending on which fan speed is currently running.
• Pet Mode will stay on unless you select a different mode or fan speed.

Auto Mode

Access additional auto modes: Quiet Auto Mode and Efficient Auto Mode.

• Quiet Auto Mode uses the medium fan speed (2 indicator lights) 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 turbo 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 dust sensor can only detect particles in the air, not smells. Efficient Auto Mode does not rely on the dust sensor, but the room size instead.

Display Lock

• Turn the Display Lock on/off.
• Display Lock prevents current settings from being changed on the air purifier.
• will flash to indicate that the display is locked.

Schedules

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

Timer Function

• Easily view the exact time remaining on a timer.

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.

1. Washable Pre-Filter
   • Captures large particles such as dust, lint, fibers, hair, and pet fur.
   • Maximizes the filter's life by protecting it.
   • Removable and washable to increase filtering efficiency (see Cleaning the Pre-Filter).
2. H13 True HEPA Filter
   • HEPASmart™ Technology uses statically charged fibers to capture viruses and bacteria with greater efficiency.
   • Traps at least 99.97% of airborne particles 0.3 microns in size.
   • Filters small particles such as fine dust, smoke particles, and allergens such as pollen and pet dander.
3. High-Efficiency Activated Carbon Filter
   • Physically adsorbs smoke, odors, and fumes.
   • Filters compounds such as formaldehyde, benzene, ammonia, hydrogen sulfide, 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.

Note: Levoit has not tested its air purifiers for effectiveness against SARS-CoV-2 and makes no claims that these air purifiers help reduce the spread of COVID-19.

Clean Air Delivery Rate

This air purifier has a Clean Air Delivery Rate of 141 cubic feet per minute (CFM), or 240 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 are calculated on 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 times per hour at the max speed in a single, closed room up to 219 ft² / 20 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 548 ft² / 50 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 85% RH or below. 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

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 after about 9 months. You may not need to change your filter yet, but you should check it when lights up.

When your air purifier is set up with the VeSync app, you can also check the app to see the remaining filter life. You will also receive a notification from VeSync when it's time to check your filter.

Note: 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.
