Dual-Stage High-Efficiency Filtration

This replacement set utilizes a specialized two-stage approach to provide clinical-level air purity:

• True HEPA Filter: Captures 99.97% of ultra-fine airborne particles as small as 0.3 microns. It is highly effective at removing pollen, dust, pet dander, smoke, and other common allergens that can trigger respiratory discomfort.

• Activated Carbon Filter: A high-capacity adsorption layer designed to reduce VOCs and neutralize unpleasant household odors from heavy cooking, cigarettes, and pets, ensuring your air stays fresh and crisp.

• Flagship Performance: Engineered to meet the demands of the 400 series, providing consistent, powerful protection against both microscopic particles and gaseous pollutants.

For optimal performance and to maintain the highest air quality, it is recommended to replace the filter set every 12 months, or as prompted by your device’s smart air quality indicators.
