  • Replacing the carbon filter

    To keep your carbon filter working effectively, we recommend changing it at least every 8,760 hours, or sooner if necessary.

  • Replacing the HEPA filter

    The fully sealed HEPA filter only needs replacing every 21,900 hours of use.¹ Located in the outer cover, it’s quick and easy to change.

¹Filter life is determined by dividing total dust load capacity by annual dust load. Annual dust load was calculated using GB/T 18801 daily mass formula. Results may vary in practice.
