At Blueair, we go to any length to increase cleaning efficiency – even if it means putting spandex on our air purifiers. The fabric pre-filter catches larger particles, extending the life of the main filter. Just vacuum it or put it in your washing machine when it needs cleaning.
Instead of making our pre-filter in only one color, you can choose from three vibrant fabrics. That’s way more fun! Match your personality or redecorate your room. Or buy all three and change colors according to your mood? All it takes is a few seconds!
