Core Features

▶ 1. Smart "Breathing", Fully Automated Purification

Equipped with a high-precision laser sensor to detect subtle changes in PM2.5/PM1.0 in real-time. Like an intelligent housekeeper, the main control board makes autonomous decisions to dynamically adjust airflow: automatically accelerating purification when pollution hits, and quietly returning to low speed once the air is clean. Users enjoy continuous pure air without any operation, achieving ultimate energy savings.

▶ 2. Peaceful Sleep, Guarding Quiet Moments

One-touch activation of exclusive Sleep Mode. The fan runs at the lowest speed, and all screens and indicators turn off, achieving "zero light and zero noise interference" to guard a comfortable night's sleep with gentle breathing.

▶ 3. Comprehensive Protection, Safe & Secure

Built-in multiple hardware-level safety lines (Over-current/Over-voltage/Short-circuit protection, Surge protection, Door detection), acting like a "safe box" for the device, significantly improving lifespan and reliability. The Child Lock function effectively prevents accidental touches, giving families with children peace of mind.

▶ 4. Visible Purity, Transparent Interaction

Supports various colorful displays to clearly present Air Quality, Temp/Humidity, and Filter Life. Making "purification effects visible" greatly enhances user trust. Smart filter reminders are calculated based on actual usage, prompting timely replacement to ensure consistent performance and prevent secondary pollution.

▶ 5. Whole-House Intelligence, Response on Call

Reserved standard Wi-Fi/Bluetooth interface for easy App remote control, scheduling, and OTA upgrades. Compatible with mainstream voice assistants (e.g., Google Assistant, Alexa), allowing users to control via voice commands, seamlessly integrating into the smart home ecosystem.

▶ 6. High Efficiency & Silence, Powered by Strong Core

Utilizes advanced Brushless DC (BLDC) motor drive technology, supporting stepless precise speed control. Compared to traditional motors, it significantly reduces energy consumption while delivering powerful airflow, operating quieter and lasting longer—perfectly balancing performance and efficiency.

▶ 7. Proven Quality, Reliable Promise

Adopts industrial-grade components and optimized PCB design to ensure long-term stable operation in complex home environments. This not only lowers after-sales costs but also serves as a solid endorsement for product durability and a premium brand image.
