Air Purifier for Large Rooms with HEPA Filter and PM2.5 Sensor

Precision Air Monitoring for Large Spaces This air purifier is built to handle spaces up to 1400 sq ft, making it suitable for living rooms, bedrooms, and open-plan areas. It includes an integrated PM2.5 sensor that continuously measures airborne particle levels and displays the data in real time. A visual indicator shows air condition levels for quick monitor during use. Its internal airflow system cycles air through the filtration chamber at a steady rate. Automated Filtration with Multi-stage System The purifier uses a 3-stage filtration structure that captures common airborne particles such as dust, pollen, smoke, and pet dander. The HEPA filter layer works alongside pre-filter and secondary filtration layers to trap particles at different sizes. In auto mode, the system adjusts fan speed based on detected air conditions, increasing airflow when particle levels rise. The unit circulates indoor air through repeated cycles to maintain airflow in large spaces. Users can select from three fan speed settings using the button control panel. The display provides ongoing feedback so adjustments can be made when needed. Low-noise Operation This unit operates at a minimum noise level of 20 dB in sleep mode, making it suitable for nighttime use in bedrooms. The control panel uses clearly labeled buttons for adjusting fan speed, activating auto mode, and enabling child lock. The child lock function helps prevent unintended changes during operation. The filter requires replacement every 3 to 6 months depending on usage. Product Benefits Real-Time Monitoring: PM2.5 sensor displays current airborne particle levels during operation.
