PM2.5 Display

The PM2.5 value on the display shows the number of airborne particles (µg) that are detected per 1 cubic meter (m³) of air volume.
PM2.5 refers to particulate matter (PM) that is less than or equal to 2.5 microns (µm) in diameter. These particles, also known as “fine particles”, are so small that they can only be detected with an electron microscope, and they stay in the air longer than heavier particles such as dust and mold.
Your air purifier’s AirSight Plus Laser Dust Sensor 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 115 indicates that there is an unhealthy amount of fine particles in the air.

Description

The Levoit True HEPA Air Purifier LAP-C601S-WUS features a three-stage filtration system. The pre-filter captures large particles like hair and dust, the True HEPA filter traps 99.97% of particles as small as 0.3 microns, and the activated carbon filter eliminates odors and gases. This comprehensive system ensures that the air in your space is clean and fresh.

The device is equipped with an auto mode that adjusts the fan speed based on the air quality detected by the built-in sensor. It also includes a pet allergy mode that boosts the fan speed to handle pet dander and odors more effectively. The night light feature provides a soft glow, making it suitable for bedrooms.

VeSync App Functions

The sync app allows you to access additional smart air purifier functions, including those listed below. As the app develops, more features may become available.

Filter Replacement Info

Keep tabs on the remaining filter life by checking the filter life percentage in the app.
Shop for replacement filters.

Auto Mode

Access additional auto modes: Quiet Auto Mode, Efficient Auto Mode, and ECO Auto Mode.
Quiet Auto Mode only uses low and medium 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 highest fan speed (turbo) 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 model 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 sensor can only detect particles in the air, not smells. Efficient Auto Mode does not rely only on the sensor, but also the room size.

ECO Auto Mode allows the fan speed to turn on/off intermittently when air quality is Very Good, to save electricity. When air quality is poor, the fan speed will be increased like standard Auto Mode.

ABOUT THE FILTER

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

A. Pre-Filter

Captures large particles such as dust, lint, fibers, hair, and pet fur.
Maximizes the filter’s life by protecting it.

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.

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).

Note: 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.

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 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.
