Blue Pure 231

Completely filters the air in a 50m² room every 12,5 minutes

Clean air for a healthier, happier space

The fabric pre-filter provides a first layer of protection by pre-catching large particles, thus extending the life of the main filter.
The particle + activated carbon composite filter is an activated carbon layer that can filter out odors caused by pets, cooking and smoking in the home, while the particle main filter can be used to remove particles suspended in the air, such as pollen, dust, pet dander, etc.
Customizable pre-filter The pre-filter is available in a variety of colors, allowing you to choose the color that matches the space environment. These colorful fabrics double as pre-filters, capturing large particles and extending the life of the main filter. If cleaning is necessary, simply vacuum it or throw it in the washing machine. After removing the pre-filter, the machine has a fresh Scandinavian look. Sleep soundly and peacefully In the lowest fan speed mode, you can enjoy a virtually silent noise level (32 dB), while in the highest operating mode, the noise level is only comparable to that of rainfall (56 dB). Place as you like Unlike other air purifiers with strict placement criteria, Blue Pure 211+ features a 360-degree air inlet design, allowing you to place it anywhere without affecting its performance. Low energy consumption This air purifier is rated as the best energy-saving product (30-61 watts) by Energy Star. Certified air purifiers use 40% less energy than ordinary models, so you can run it 24 hours a day without worrying about power consumption.

Designed for large rooms

In a 15.2 square meter room, the industry-recommended air exchange rate of 4.8 times per hour (or approximately once every 12.5 minutes) can be used to thoroughly purify the indoor air, effectively reducing the concentration of particles, creating a comfortable environment for you in large living rooms, family rooms and game areas.

The secret behind the superb filtration performance

Our unique combination of electrostatic and mechanical filtration technologies, HEPASilent filtration technology, sets us apart in the industry. This combination of technologies allows us to use a lower density filter material, which requires lower air pressure than traditional HEPA filters without sacrificing performance, resulting in ultra-quiet operation of the air purifier and greater energy efficiency.
