Description
Dust in indoor spaces is not just something that settles on surfaces; it also remains in the air, circulating throughout the room. This can make the space feel less clean over time, even after regular cleaning. Replacing the filter helps your DustMagnet™ 5440i continue capturing airborne dust effectively while maintaining consistent air quality and performance.
- Genuine Blueair ComboFilter for DustMagnet™ 5440i: Designed specifically for the 5440i to ensure correct fit, balanced airflow, and reliable long-term performance. Using an original filter helps maintain the purifier’s ability to capture airborne dust efficiently.
- DustMagnet™ technology for capturing dust before it settles: Uses dual air intake and vortex airflow to keep airborne dust particles moving, while electrostatic charging clusters them together. Once inside, particles attach to charged pre-filters, helping reduce dust settling on surfaces.
- Dual filter placement for optimal performance: Includes filters positioned at both the top and bottom of the unit, allowing more effective air intake and improved particle capture from different directions within the room.
- Particle and carbon filtration combined: Integrates a particle filter for dust, allergens, and fine particles with an activated carbon layer that absorbs VOCs, smoke, chemicals, and light household odours from pets, cooking, and indoor air.
- Efficient removal of everyday pollutants: Helps reduce dust, pollen, pet dander, smoke particles, bacteria, and airborne contaminants commonly found in indoor environments affected by pollution and daily activity.
- HEPASilent™ filtration support: Combines mechanical filtration with electrostatic particle charging to improve air cleaning efficiency while maintaining lower noise and energy use compared to traditional HEPA-only systems.
- Smart filter tracking and replacement support: Works with the purifier’s system to track usage and notify when replacement is needed, ensuring consistent performance without guesswork.
- Long filter lifespan for convenience: Designed to last up to 1 year depending on air quality and usage conditions, reducing the need for frequent replacements.
- Optimised airflow and filter efficiency: Designed to maintain airflow over time while capturing particles effectively, preventing early clogging and ensuring consistent purification performance.
- Certified performance and safety: Independently tested for air cleaning performance, with AHAM verification for CADR and CARB certification for ozone safety, including zero ozone emissions.
- Practical usage guidance: Replace when notified by the purifier or app to maintain dust capture efficiency and overall air quality. Using genuine filters ensures proper fit and long-term reliability.
