General Safety

  • Only use your air purifier as described in this manual.
  • Do not use your air purifier outdoors.
  • Keep your air purifier away from water, and wet or damp areas. Never place in water or other liquids.
  • Keep your air purifier away from heat sources.
  • Do not use where combustible gases or 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 place anything into any opening on the air purifier.
  • Do not sit 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.
  • Always unplug your air purifier before servicing (for example, changing the filter).
  • Do not use your 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 (see page 17).
  • WARNING: To reduce the risk of fire or electric shock, do not use this air purifier with solid-state speed controls (such as a dimmer switch).
  • Not for commercial use. Household use only.

Plug & 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.
  • Your air purifier has a polarized plug (one prong is wider than the other), which fits into a polarized outlet only one way. This is a safety feature to reduce the risk of electric shock. If the plug does not fit, reverse the plug. If it still does not fit, do not use the plug in that outlet. Do not bypass this safety feature.

PM2.5 Value & Air Quality
The PM2.5 value on the display shows the amount of particles (µg) that are detected within 1 cubic meter (m³). PM2.5 refers to particulate matter (PM) that is less than or equal to 2.5 micrometers (µm) in diameter. These particles, also known as “fine particles”, are so small that they can only be detected with an electron microscope, and stay in the air longer than heavier air particles such as dust and mold. Your air purifier is equipped with a laser dust sensor that 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 135 indicates that there is an unhealthy amount of fine particles in the air.

You can set a timer between 1– 12 hours.

  1. Tap repeatedly (or press and ) to set a time.
  2. Once you choose a time, the timer will flash 5 times and start counting down.
  3. The air purifier will automatically turn off once the timer is finished.
  4. To cancel a timer, tap repeatedly until the timer reads “- – – -”. The timer will flash 5 times to confirm cancellation.
    • You can change the fan speed at any time while the timer is counting down. The timer will work with any mode.
    • Pressing or unplugging the air  purifier will cancel the timer.

Memory Function
The air purifier will remember its programmed settings when turned off, and will resume these settings when it is turned back on. The air purifier must remain plugged in for the memory function to work.
The air purifier will not remember timers.

The True HEPA Combination Filter uses a 3-stage filtration system to purify air.

  • Nylon Pre-Filter
  • Captures large particles such as dust, lint, fibers, hair, and pet fur.
  • Maximizes the life of the True HEPA Filter by protecting it.
  • H13 True HEPA Filter
  • Removes at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter.
  • Filters small particles such as fine dust, smoke particles, and allergens such as pollen and pet dander.
  • 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).
    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.


Cleaning the Air Purifier

  1. Wipe the outside of the air purifier with a dry cloth. Do not clean with water or any other liquid to avoid risk of electric shock.
  2. Clean the outside of the filter with a brush or vacuum hose each month to prevent buildup of hair or dust. Do not clean the filter with water or other liquids.

Check Filter Indicator

  2. Turn on the air purifier.

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 if the 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

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

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

  2. Remove the old filter. [Figure 3.2]
  3. Clean any dust or dirt from inside the housing. [Figure 3.3]
