Features
1. Multi-Layer HEPA Filtration (H13 Grade): The filter integrates a true H13-grade HEPA layer, capturing 99.97% of particles as small as 0.3 microns, including PM2.5, allergens, and airborne pathogens. Independent lab tests confirm a particle retention efficiency of ≥99.95% at 0.1–0.2 microns, exceeding standard HEPA benchmarks.
2. Activated Carbon Layer for VOC Adsorption: A 450g/m² high-density activated carbon mesh neutralizes volatile organic compounds (VOCs) like formaldehyde (adsorption rate: ≥92% @ 1h exposure) and odors. The carbon’s iodine value exceeds 1000 mg/g, ensuring superior chemical adsorption capacity.
3. Antibacterial Coating (Ag+ Ion Technology): The filter’s polypropylene framework is infused with silver-ion antimicrobial agents, inhibiting bacterial growth (tested 99.9% reduction against E. coli and S. aureus per ISO 22196). This extends filter lifespan while preventing secondary pollution.
4. Low Airflow Resistance (≤28 Pa @ 200 m³/h): Engineered with a pleated design (120% expanded surface area), it maintains a static pressure drop below 30 Pa at rated airflow, reducing energy consumption by ~15% compared to conventional filters.
5. Long Service Life (6–8 Months): With a dust holding capacity of 18,000 mg (per EN 779:2012), the filter operates optimally for 6,000+ hours in moderate pollution (PM2.5 ≤75 µg/m³). An integrated RFID chip tracks usage and alerts replacements via the Mijia app.
6. Precision Fit & Leakage Prevention: Laser-cut gaskets and a ±0.2mm tolerance frame ensure a seal efficiency >99.8%, verified via ASTM F3502-21 testing. Compatible with Mijia models AC-M6-SC, V1, and V3 without airflow bypass.
Whether in your home, office, restaurant, hotel or medical institution, this air purifier filter can provide clean indoor air for a healthier and more comfortable environment for yourself and others.
