For office buildings, shopping centers, hotels, airports, museums and other commercial spaces, Yiran® provides multi-stage combined filtration solutions to effectively address Sick Building Syndrome (SBS), high-energy HVAC operation, IAQ compliance and other core challenges. Referencing the ISO 16890 international standard, we create healthy, comfortable and energy-efficient indoor air environments for building occupants.
Modern people spend over 90% of their time indoors. Commercial building air quality directly impacts occupant health, comfort and work efficiency, while also being a major factor in HVAC system energy consumption.
Insufficient fresh air and low filtration efficiency lead to accumulation of indoor pollutants. PM2.5, VOCs, CO₂ concentrations exceed limits, causing headaches, fatigue, respiratory discomfort and other symptoms. WHO data shows approximately 30% of office buildings worldwide have varying degrees of SBS issues, resulting in reduced attendance and 15-20% productivity loss.
Traditional low-efficiency filters create high resistance, forcing fans to operate at higher power to maintain set airflow. In large commercial buildings, HVAC systems consume 40-60% of total energy, with fans accounting for 30-40%. Every 50Pa increase in filter pressure drop adds tens of thousands in annual energy costs.
Low dust-holding capacity filters have short lifespans and require frequent replacement, increasing procurement costs. Multiple shutdowns disrupt building operations. Large commercial buildings can incur hundreds of thousands in annual filter replacement costs, with elevated work also posing safety risks.
LEED, WELL, BREEAM and other green building certifications impose quantified indoor air quality requirements. GB/T 18883 Indoor Air Quality Standard strictly mandates PM2.5 ≤35μg/m³ and CO₂ ≤1000ppm. Compliant filtration solutions must balance efficiency, pressure drop and service life holistically from the design stage.
Yiran® standard commercial building solution employs a three-stage filtration configuration, with optional enhanced final-stage filtration where required, achieving a complete chain from coarse interception to high-efficiency purification.
