Overview

Understanding Plasma Technology

Plasma is a material form consisting mainly of free electrons and charged ions, often considered to be the fourth state of matter, called the plasma state. Plasma has very high conductivity and strong coupling with electromagnetic fields. Strictly speaking, plasma is a gas mass with high energy and dynamic energy, which contains a large number of reactive oxygen ions. High-energy free radicals and other components can easily react with bacteria, molds, spores, and proteins and nucleic acids in viruses to denature them and cause various microorganisms to die.

The product generates a small amount of ozone while generating plasma. This amount is not sufficient to be harmful to the human body, and the internal 3G filter can effectively filter any trace amount if present.

Main sterilization: Plasma technology

Sterilization strength: Plasma density 3.46x10¹⁴ m^-3

Effective against type of microorganisms: Common bacteria in the air

Sterilization rate for staphylococcus albus (8032): ≥99.9%

Ideal Use

It is suitable for use in enclosed environments such as libraries, museums, office buildings, and homes, where the air is confined within a space. The LAS302 can eliminate bacteria and viruses with 99.9% efficacy.

How does the LAS302 work?

A. Sterilization function: Plasma Generator

B. Through the rotating of fan blades, the product pumps indoor air from the bottom and releases it out from the top, allowing the air to filter via prefilter, plasma generator, and 3G filter. This three-step filtration sterilizes and eliminates bacteria completely as the machine continues to circulate clean air.

C. The operating principle is illustrated as below:

Features

Control Buttons and Indicators:

• Photosensitive sensor/OLED display screen: Displays air quality, filter status, and mode information.
• Touch control buttons: Located on the top of the unit.

Air Quality Indicator Levels:

• Good
• Moderate
• Unhealthy for sensitive people
• Unhealthy
• Very unhealthy
• Hazardous

After successful connection, the network icon shows the current signal strength. Remote upgrade (OTA) can be performed if necessary.

3G filter/pre-filter lifespan check and reset:

• Press once to display the 3G filter lifespan.
• Press twice to display the prefilter lifespan.
• Press and hold the respective button to enter the lifespan reset interface and then press and hold again to reset the lifespan.

Standard Selection: Select the air quality standard (Chinese or American) as the operating standard. If the American standard is selected, the product will operate at higher levels, especially at night.

Device Information: Press and hold the [ℹ️] buttons simultaneously to check device information.

Note: Do not block the sterilizer's opening.

Do Not Tilt

Note: Use with caution and avoid tilting the product! When it is tilted, a built-in sensor will turn off the unit, so as to avoid damage to the product and its parts.

Manually Control Fan Speed

Easy to operate:

• Touch the top circle of the main unit and rotate clockwise to increase the fan speed.
• Touch the top circle of the main unit and rotate counterclockwise to decrease the fan speed.

Meanwhile, the display screen will show the current indoor PM2.5 and PM10 value and prefilter lifespan.

The product has a reminder feature. When the "Prefilter Lifespan" or "3G Filter Lifespan" indicated by the display screen reaches below 5%, the APP will alert you to clean or replace soon.

Check Manually:

Press the [?/?] button once to check 3G filter lifespan.

Press the [?/?] button twice to check prefilter lifespan.

Filter Lifespan Reset:

After replacing the 3G filter: Press the [?] button once to display the 3G filter lifespan, then press and hold the [?] button to enter the 3G filter lifespan reset interface, and press and hold again to reset the 3G filter lifespan, so as to restart the smart monitoring for the 3G filter lifespan.

After cleaning the prefilter: Press the [?] button twice to display the prefilter lifespan, then press and hold the [?] button to enter the prefilter lifespan reset interface, and press and hold again to reset the prefilter lifespan, so as to restart the smart monitoring for the prefilter lifespan.

Confirmation Prompts: "Reset 3G Filter? Press and Hold to Confirm" and "Reset Prefilter? Press and Hold to Confirm" are shown, followed by "3G Filter Reset Successful" and "Prefilter Reset Successful".

Warning: To minimize error, do not remove the prefilter. If it is damaged, please replace it from authorized dealers only.
