Description
Keeping your air purifier performing at its best requires the right filter. Over time, dust, pollutants, and odours build up inside the filter, reducing airflow and efficiency. Replacing it with a genuine SmartFilter ensures your HealthProtect™ 7470i continues to deliver consistent air cleaning and balanced performance.
- Genuine Blueair SmartFilter: Designed specifically for the HealthProtect™ 7400 Series, including HealthProtect™ 7470i and HealthProtect™ 7475i, it ensures proper fit, stable airflow, and reliable long-term performance. Using an original filter helps maintain the purifier’s intended efficiency without performance drops.
- HEPASilent Ultra™ filtration technology: Combines electrostatic charging with mechanical filtration to deliver up to 50% more clean air than traditional HEPA filters while using 55% less energy and producing 10% less noise. Engineered in Sweden for efficient and quiet operation.
- Multi-layer filtration for particles, gases, and odours: Integrates particle filtration with activated carbon to capture dust, pollen, pet dander, mould spores, smoke particles, bacteria, and airborne pollutants, while also reducing VOCs, exhaust smells, chemicals, and indoor odours.
- High-efficiency removal of airborne contaminants: Designed to capture up to 99.97% of particles, including fine dust, allergens, bacteria, and viruses, down to very small sizes. Helps maintain cleaner air in spaces affected by pollution and everyday indoor contaminants.
- GermShield™ technology for continuous protection: Supports GermShield™ functionality that helps deactivate up to 99% of germs captured on the filter. Continues working even when the purifier is on standby, using low airflow and plasma charge.
- SmartFilter with RFID tracking: Includes a built-in RFID chip that communicates directly with the purifier. Automatically resets filter life status and allows easy monitoring through the app without manual input.
- Accurate filter life tracking based on real usage: Uses an algorithm that considers fan speed, pollutant levels, and operating conditions to calculate filter lifespan. Ensures timely replacement without guesswork.
- Long filter lifespan for convenience: Designed to last approximately 6 to 12 months, depending on air quality and usage. Maintains stable performance while reducing the need for frequent replacements.
- Optimised booklet-style filter design: Increases surface area for improved particle capture and airflow. Helps trap pollutants inside the filter and prevents early clogging during removal and use.
- Advanced filter composition: Made from polypropylene fibre media without chemical binders, combined with activated carbon infused with magnesium dioxide and copper oxide for enhanced gas and odour absorption.
- Quiet, energy-efficient performance support: A less dense filter structure allows efficient airflow at lower fan pressure, reducing energy use and helping maintain quieter purifier operation.
- Certified performance and safety: Independently tested for filtration performance and meets recognised standards, including HEPA-grade filtration performance and zero ozone emissions.
- Developed for high-performance environments: Filter technology is based on systems used in industries such as healthcare, pharmaceuticals, aerospace, and electronics manufacturing, where air purity is critical.
- Simple replacement and maintenance: Switch off and unplug the unit, open the side panel, remove the used filter using the fabric handles, and replace it with a new one. Regular replacement helps maintain airflow and extend the purifier’s life.
