General Safety

  • Only use your air purifier as described in this manual.
  • Do not use without removing the plastic wrap from the filter. The air purifier will not filter air and may overheat, causing a fire hazard.
  • Do not use the air purifier outdoors.
  • Keep the air purifier away from water, and wet or damp areas. Never place it in water or liquid.
  • Do not use in excessively humid areas.
  • Keep the air purifier away from heat sources.
  • Do not use where combustible gases, vapors, metallic dust, aerosol (spray) products, or fumes from industrial oil are present.
  • Keep 5 ft / 1.5 m away from where oxygen is being administered.
  • Supervise children when they are near the air purifier. Do not allow children to play with the air purifier.
  • Do not place anything into any opening in the air purifier.
  • Do not sit on or place heavy objects on the air purifier.
  • Keep the inside of the air purifier dry. To prevent moisture buildup, avoid placing in rooms with major temperature changes or underneath air conditioners.
  • Always unplug the air purifier before servicing (such as changing the filter).
  • Do not use the air purifier if it is damaged or not working correctly, or if the cord or plug is damaged. Do not try to repair it yourself. Contact Customer Support
  • WARNING: To reduce the risk of fire or electric shock, do not use this air purifier with any solid-state speed controls (such as a dimmer switch).
  • Children should not clean or perform maintenance on the air purifier without supervision.
  • • This air purifier is not to be used by persons (including children) with reduced physical, sensory, or mental capacities, or lack of experience and knowledge.

Power & Cord

  • Keep the air purifier near the outlet it is plugged into.
  • Never place the cord near any heat source.
  • Do not cover the cord with a rug, carpet, or other covering. Do not place the cord under furniture or appliances.
  • Keep the cord out of areas where people walk often. Place the cord where it will not be tripped over.
  • This appliance has a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician. Do not attempt to defeat this safety feature.
  • This air purifier uses standard North American 120V, 60Hz outlets. If using outside the US or Canada, check for compatibility.
  • If the power supply cord is damaged, it must be replaced by Arovast Corporation or similarly qualified persons in order to avoid an electric or fire hazard. Please contact Customer Support.

If you are not planning to use the air purifier for a long period of time, we recommend keeping the filter clean by leaving it inside its plastic packaging until it is ready to be used.


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.


  • 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, Efficient Auto Mode, and ECO Auto Mode.

Memory Function
The air purifier will remember its programmed settings when turned off and will resume these settings when turned back on.

Note: The air purifier will not remember timers.

Air Quality Indicator

Indicator Color Air Quality Fan Speed

The air purifier uses a 3-stage filtration system to purify air.

Levoit LV-H134 Pro HEPA Air Purifier User Manual fig 6

  1. A. Pre-Filter 
    • Captures large particles such as dust, lint, fibers, hair, and pet fur.
    • Maximizes the filter’s life by protecting it.
  2. 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.
  3. C. Custom High-Efficiency Activated Carbon Filter
    • 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 secondhand pollution.
    • Filters compounds such as formaldehyde, benzene, ammonia, hydrogen sulfide, and volatile organic compounds (VOCs).

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.

Clean Air Delivery Rate
This air purifier has a Clean Air Delivery Rate of 212 cubic feet per minute (CFM), or 360 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 the 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

For smaller rooms, the air change per hour will increase. This air purifier has an air change per hour of 3.4, which means it can change air 3.4 times at the max speed in a single, closed room up to 463 ft² / 43 m². The air purifier is effective for larger rooms, but air purification will take longer, with fewer air changes per hour.

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 will 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 filters will become damaged by the oil and will eventually release an unpleasant smell. Do not use oil diffusers near the air purifier.


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
Levoit 600S VeSync Core Air Purifier User Manual fig 13

will light up as a reminder to check the filter. If you use your air purifier consistently (24 hours of daily use), the indicator should turn on after about 6–12 months. You may not need to change your filter yet, but you should check it when Levoit 600S VeSync Core Air Purifier User Manual fig 13 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.

Cleaning the Sensor Cover 

If the air quality indicator does not seem to be accurate, clean the sensor cover.

  1. Remove the sensor cover. [Figure 2.1]
    Note: The sensor cover has a sponge inside to protect the air quality sensor from large particles.
  2. Wipe the cover with a dry cloth. Wash the sponge with clean water, then dry.
  3. Replace the sponge with the sensor cover, and then replace the sensor cover.
    Note: Do not throw away the sponge. If the sponge is not in the sensor cover, the air quality sensor may not work correctly.

Levoit LV-H135 True HEPA Air Purifier Manual fig 8

When Should I Replace the Filter?
The filter should be replaced every 6–8 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 change the filter more often, even ifLevoit 600S VeSync Core Air Purifier User Manual fig 13is off. You may need to replace your filter if you notice:

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


  • To maintain the performance of your air purifier, only use official Levoit filters. To buy replacement filters, visit Levoit’s online store. Go to levoit.com for more information.
