The bottom part of each Pure 121 air purifier mainly consists of an advanced mechanical filter with the fan. Using this advanced combination of mechanical and electrostatic filtration, the Pure 121 catches airborne contaminants down to the size of viruses, plus pollen, dust, pet dander, mold spores, smoke, allergens and bacteria. The carbon mesh filter even removes odors, gases and VOCs. And with its unique 360° air intake, every Blue 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.
