Moisture-absorbing, dust-removing, and odor-decomposing air purifier | Color-changing silica gel + activated carbon + photocatalyst

🌀 Three-stage purification system → 1. Color-changing silica gel quickly absorbs moisture | 2. Activated carbon adsorbs fine dust and odors | 3. Photocatalyst decomposes formaldehyde and TVOC 🎨 Intelligent humidity visualization → Silica gel particles change color with humidity | Blue (dry) → Pink (saturated) for easy viewing ♻️ Renewable and reusable → After saturation, microwave heating for 3 minutes or sun exposure will restore activity Suitable scenarios: Moisture-proof and odor-removing | Bathroom and toilet antibacterial | Car air conditioning odor removal | Pet area air purification | Study and document mold prevention
