This standard applies to car air purification systems for passenger elevators, medical elevators and home elevators, covering three categories: fresh air type, circulation purification type and composite type. Core contents include:

First, Core Performance Indicators, mandating PM2.5 removal rate ≥95%, formaldehyde removal rate ≥90%, bacteria killing rate ≥99.9%, virus inactivation rate ≥99%, fresh air volume ≥30m³/(person·hour), CO₂ concentration in car ≤1000ppm, noise ≤45dB(A);

Second, Purification Technical Specifications, supporting five technologies: HEPA high-efficiency filtration, UV-C ultraviolet sterilization, anion purification, photocatalyst and activated carbon adsorption, clarifying applicable scenarios, service life and replacement cycle of different technologies (HEPA filter ≥6 months, UV-C lamp ≥12 months);

Third, Installation and Structure Requirements, purification system must be integrated into car ceiling/side wall without occupying effective space, equipped with anti-vibration, dustproof, waterproof and anti-leakage functions, and electrically interlocked with elevator operation system (automatically starts when elevator runs, low-power standby when stopped);

Fourth, Testing and Acceptance Standards, formulating four test items: static purification efficiency, dynamic circulation effect, continuous operation stability and noise test, clarifying qualification criteria, and unqualified elevators are strictly prohibited from being put into use;

Fifth, O&M and Management Specifications, specifying cycles of monthly inspection, quarterly filter replacement and annual performance testing, establishing a whole-process management system of purification effect monitoring, fault alarm and maintenance records.


After implementation, this standard will promote China's elevator industry to enter a new stage of healthy and high-quality development, provide healthy elevator standard solutions for overseas high-end residential, medical and commercial projects, and enhance the international competitiveness of Chinese elevator products.
