SAFETY INFORMATION

To reduce the risk of fire, electric shock, or other injury, follow all instructions and safety guidelines.

General Safety

• Only use your air purifier as described in this manual.
• Do not use without removing the plastic wrap from the filter. The purifier will not filter air, and may overheat, causing a fire hazard.
• Do not use your air purifier outdoors.
• Keep your air purifier away from water, and wet or damp areas. Never place in water or liquid.
• Do not use in excessively humid areas.
• Keep your 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 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 or underneath air conditioners.
• Always unplug your air purifier before servicing (such as 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.
• 
  Do not use this air purifier with solid-state speed controls (such as a dimmer switch).
• Not for commercial use. Household use only.

Power & Cord

• Keep 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 US 120V, 60Hz outlets. If using outside of the US, check for compatibility.

ABOUT THE FILTER

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

1. Pre-Filter
   • Captures large particles such as dust, lint, fibers, hair, and pet fur.
   • Maximizes the filter's life by protecting it.
2. True HEPA Original Filter
   • Removes at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter.
   • Filters small particles such as mold spores, tiny dust particles, parts of smoke, and allergens such as pollen, dander, and mites.
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).

Clean Air Delivery Rate

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. The Core 300 has an air change per hour of 5, which means it can change air 5 times at the max speed. This purifier is suggested for use in a single, closed room up to 219 ft² / 20 m².

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 will become moldy.

Note: Water or moisture will allow mold to grow. Air purifiers cannot solve an existing mold problem, only remove mold spores and reduce odors.

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 oil diffusers near the purifier.

Cleaning the Filter

The outer pre-filter should be cleaned every 2–4 weeks to increase the 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 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 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

• Unusual odors
• A visibly clogged filter

Note:

• 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.
