Research shows that indoor air is up to five times more polluted than outdoor air. Blue Pure 221 cleans the entire volume of air in a 50 m² (540 ft²) room completely five times per hour – and keeps it perfectly clean. Creating your personal safe haven, with air as clean as at the greatest outdoor locations on earth. If your room is smaller, the air gets cleaned even faster and more often.
Intuitive one-button control makes the Blue Pure 221 really easy to use. Just plug it in and turn it on. Your first touch on the single button automatically sets it to the recommended operating speed. Furthermore, Blue Pure 221 is whisper silent.
The entire bottom half of the Blue Pure 221 consists of an advanced filter. Millions of ultra-thin fibers of different layers make it less dense than ordinary filters. Resulting in less clogging, higher airflow and lower noise. Using both mechanical and electrostatic filtration, the filter catches virtually every airborne contaminant down to a virus in size: pollen, dust, pet dander, mold spores, smoke, allergens and bacteria. When you finally have to replace the filter, you don’t have to be an engineer. All you need is two index fingers and one click.
Thanks to optional fabric pre-filters in different energizing colors, you can easily redecorate your room in seconds. Bonus: The pre-filter catches larger particles, extending the life of the main filter. Just gently vacuum it or put it in your washing machine when it requires cleaning. If you prefer the look of our high-quality steel mesh, you can of course use your Blue Pure 221 without any pre-filter.
