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.

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

Levoit Core 300 True HEPA Air Purifier Manual fig 8

  1. A. 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.
  2. B. H13 True HEPA Filter
    • Captures at least 99.97% of airborne particles 0.3 microns (µm) in size.
    • Filters small particles such as fine dust, smoke particles, and allergens such as pollen and pet
  3. C. Custom 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.

Clean Air Delivery Rate
This air purifier has a Clean Air Delivery Rate of 410 cubic feet per minute (CFM), or 697 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

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 times per hour at the max speed in a single, closed room up to 635 ft² / 59 m². This is measured at 5 ACH. 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 1588 ft² / 147 m² based on 2 ACH, or purifying the air in the room 2 times per hour.

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

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 moldy.

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.


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 13will 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.

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.

When Should I Replace the Filters?

The filters should be replaced every 6–8 months. You may need to replace your filters 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 filters more often (even if the Check Filter Indicator is off). You may need to replace your filters if you notice:

  • Increased noise when the air purifier is on
  • Decreased airflow
  • Unusual odors
  • Visibly clogged filters.

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.

Replacing the Filters

  1. Unplug the air purifier. Flip the air purifier over and remove the filter cover.
  2. Remove the old filters.
  3. Clean any remaining dust or hair inside the air purifier using a vacuum hose. Do not use water or liquids to clean the air purifier.
  4. Unwrap the new filters and place them into the housing.
  5. Replace the cover and plug in the air purifier.
  6. Reset the Check Filter Indicator.

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