Blue 3210 Particle filter + Carbon sheet
Designed for Small Rooms
Filters the air approximately 4.8 times per hour (every 12.5 minutes) in a 17 m² room, effectively removing over 99% of particles such as dust, pollen, mold, and pet dander — all common allergy triggers.
Clean Air With One Touch
The one-touch auto mode is designed to help maintain a comfortable and safe home environment.
When activated, this function automatically adjusts the fan speed based on real-time conditions detected by the integrated particle sensor.
Stay informed with the LED indicator, which changes color to indicate whether your air quality is good, moderately polluted, or polluted.
Three-Stage Filtration
The pre-filter acts as the first filtration layer, capturing larger particles and extending the lifespan of the main filter.
A combination of particle + carbon filtration using activated carbon helps filter light household odors from pets, cooking, and smoking, while the main filter removes airborne particles like pollen, dust, pet dander, and more.
The Secret Behind Powerful Filtration
Our unique combination of electrostatic and mechanical filtration, known as HEPASilent™ technology, sets us apart.
This approach allows the use of lower-density filters than traditional True HEPA filters without sacrificing performance — resulting in quiet and energy-efficient purification.
