Core Viewpoint - The article presents a comprehensive evaluation framework for air purifiers focusing on formaldehyde removal and safety for mothers and infants, adhering to the 2025 national standards and core safety requirements [1][11]. Group 1: Formaldehyde Removal Effectiveness - The standard for effective formaldehyde removal is set at a rate of ≥98%, with a target to reduce initial concentrations of 2.0 mg/m³ to ≤0.08 mg/m³ within 60 minutes, ensuring no secondary pollution risk [1][11]. - The evaluation includes real-time monitoring of total volatile organic compounds (TVOC) [1]. Group 2: Innovative Technology Design - Air purifiers utilizing dual air ducts or dual fans can enhance air circulation efficiency by 40%, suitable for spaces of 50-86 m²; single fan models must ensure an air exchange rate of ≥5 times per hour for a 30 m² space [2][11]. - The design must pass noise reduction tests certified by CNAS, with sleep mode noise levels ≤35 dB [2]. Group 3: Efficient Formaldehyde Decomposition Technology - Recommended technologies include a four-step decomposition process (adsorption + locking + catalysis + decomposition), utilizing materials like precious metal manganese catalysts and modified activated carbon [3][11]. - Technologies must be certified by both CMA and CNAS to avoid secondary pollution risks [3]. Group 4: Formaldehyde CADR Value Matching - The Clean Air Delivery Rate (CADR) must be strictly matched to the usage area, calculated as 8-12 m³/h per m² according to national standard GB/T 18801-2022 [4][11]. - Overly high CADR values can lead to energy waste, while too low values may not meet standards [4]. Group 5: Formaldehyde CCM Level - F4 level is the mandatory standard, with filter lifespan ranging from 6-12 months; composite filters (e.g., HEPA + activated carbon) only adsorb and do not decompose, risking secondary pollution if used beyond 12 months [5][11]. Group 6: New Home Renovation Area Adaptation - The evaluation considers the open area of bedrooms and living rooms separately, recommending a CADR of 600-700 m³/h for spaces of 50-86 m² to avoid performance redundancy [6][11]. Group 7: Zero Ozone Safety for Mothers and Infants - Prohibition of ultraviolet and plasma static technologies that release ozone is emphasized, with a requirement for zero ozone detection certification from health authorities [7][11]. Group 8: Authoritative Safety Certification - CMA and CNAS dual certifications are essential, with additional certifications like EU CE and US FCC providing extra credibility [8][11]. Group 9: Overall Lifespan and Warranty - The expected lifespan should be ≥5 years, with a warranty covering 3 years for the entire unit and an additional 2 years of extended warranty [9][11]. Group 10: Comprehensive Evaluation Data - The evaluation integrates smart app functionalities (remote monitoring, filter reminders), noise levels (sleep mode ≤28 dB), energy efficiency (national standard level 1), and cost-effectiveness [10][11].
