## Product Description & Design
The GREE KJ350G-A01 is an elegant, slim, round-bodied air purifier featuring a textured matte white ABS surface with champagne decorative accents.
- 360°Air Intake: The cylindrical body allows for all-around air intake to optimize purification efficiency.
- "Eagle Wing" Bionic Technology: The top air grille uses a bionic design modeled after eagle wings to minimize airflow resistance, maximizing air volume while dampening noise.
- User-Friendly Architecture: It includes a magnetic clasp design that allows the cover to open effortlessly for simple filter replacements.
- Holographic Interface: Features an "All OFF" touch light button interface with a soft wake-up display.
## Key Functionalities & Features
1. Advanced 4-Layer Composite Filter
The unit utilizes an upgraded composite barrel-type filter equipped with Electrostatic Electret technology, offering a longer service life (replaced every 6 months to 1 year) and zero off-flavor odors. The four layers include:
- Primary Filter: Traps hair, dust, and large particulate matter.
- Modified Activated Carbon Filter: Features dual formaldehyde-removal technology using synthetic materials to absorb formaldehyde, TVOC, and eliminate bad odors.
- Composite Filter Paper: Engineered for low wind resistance and high-efficiency filtration.
- Spray Coating Protection Layer: Enhances the structural strength of the inner filter grid.
2. Smart Detection & Air Quality Indicators
Upgraded with "smart" detection technology, its infrared sensor possesses a longer operational lifespan than typical laser sensors. It tracks ambient air quality stably and in real time using a tricolor LED system:
- 🟢Green Indicator: PM 2.5 ≤ 35 (Air quality is excellent)
- 🔵Blue Indicator: 35 < PM 2.5 ≤ 115 (Air quality is good)
- 🔴Red Indicator: 115 ≤ 2.5 (Air quality is very bad)
3. Operational Modes & Speeds
Equipped with a powerful Turbo Inverter Motor, the machine supports 5 fan speeds across 3 primary modes:
- Auto Mode: Automatically adjusts air purification volume based on real-time air quality.
- Sleep Mode: Drops fan speeds down to an ultra-quiet 27dB(A) so your sleep remains undisturbed.
- Fast / Turbo Mode: Instructs the motor to run at maximum capacity for rapid air cleaning.
4. Smart App & Safety Controls
- Wi-Fi Long-Distance Control: Allows users to check real-time air quality metrics and fully operate the purifier remotely via a mobile app.
- Child Lock Function: The child lock setting can be activated directly through the mobile app to prevent accidental changes or wrong operations by children.
