YIHSZLC air filtering installations

Primary filter (polyester fiber): Captures large particles (≥5μm) like hair and dust, ≥90% efficiency.​
HEPA filter (H13 grade): Traps fine particles (≥0.3μm) such as PM2.5, pollen, and bacteria, ≥99.97% efficiency.​
Activated carbon filter (coconut shell carbon, iodine value ≥1000mg/g): Adsorbs formaldehyde, TVOC, and odors, adsorption capacity ≥800mg/g.​
Suitable for 20-100㎡ spaces, with CADR values 300-800m³/h. Reduces indoor PM2.5 from 150μg/m³ to below 35μg/m³ within 30 minutes.​
2.Smart Wind Control for Various Scenarios​
Features 3-5 wind speeds: low speed (≤35dB) for quiet bedroom use at night; high speed (≥3m/s) for heavy pollution like smog or renovation fumes. Some models have auto-sensing mode with PM2.5 sensors (±5μg/m³ accuracy), adjusting wind speed based on air quality. Automatically switches to standby when concentration ≤35μg/m³ for energy saving​
3.Durable Materials & Structure for Long-Term Stable Operation​
|Body made of cold-rolled steel (≥1.2mm thick) or ABS flame-retardant plastic (UL94 V-0), corrosion-resistant and anti-aging, with ≥8-year service life. Filter replacement cycles: primary filter (1-3 months, washable); HEPA filter (6-12 months); activated carbon filter (3-6 months). Operates at -10℃ to 40℃, ≤90%RH, suitable for homes, offices, laboratories, etc.​
