Like all Blue models, the Pure 221 is whisper silent and energy efficient (just 30 – 61 W, depending on fan speed). With the one-button speed control it’s also super easy to use. A light alerts you when it’s time to change filters, and when you do, you don’t have to be an engineer – just lift off the top, take the old filter out and pop in the new one.
The bottom part of each Pure 221 air purifier mainly consists of an advanced mechanical filter with the fan. Using this advanced combination of mechanical and electrostatic filtration, the Pure 211+ catches airborne contaminants down to the size of viruses, plus pollen, dust, pet dander, mold spores, smoke, allergens and bacteria. The combination filter with active carbon even removes odors, gases and VOCs. And thanks to the unique 360° air intake, every Blue model is fully efficient wherever you place it.
Blue air purifiers can even help you redecorate your room in seconds, thanks to fabric pre-filters in different energizing colors. As a 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.
