How It Works:

  • [Pre-Filters]: Capture larger particles like dust and pet hair before the air goes through the main filtration system, prolonging the life of other filters.

This dynamic combination of electrical charging and a strong air draft also neutralizes viruses and bacteria, providing you with a healthier and fresher living environment.
