About This

• ✅ 99.97% High-Efficiency Filtration： Captures microscopic particles as small as 0.3 microns—ideal for pet hair, pollen, and everyday dust—keeping your home air fresh and clean without triggering respiratory sensitivity.
• 🔇 Ultra-Quiet HEPASilent Technology： Combines electrostatic charge and low-density filters to purify air at a whisper-quiet 17 dB (lowest setting), perfect for bedrooms, nurseries, or offices where silence matters.
• ⏱️ 10-Second Swap, No Tools Needed： Simply twist off the purifier’s top cap, drop in the new filter, and secure. Pre-fitted frames ensure perfect alignment—even first-time users can replace it effortlessly.
• 🌿 2-in-1 Particle + Carbon Defense： Dual-layer design: HEPA traps airborne particles while activated coconut carbon absorbs cooking odors, pet scents, and VOCs. Breathe deeply in kitchens, dorms, or small apartments (up to 161 sq ft).
• ♻️ 6-Month Lifespan & Eco-Conscious： Optimized for 24/7 operation. Replace every 6 months (red indicator light reminder). Recyclable materials reduce waste—healthier air shouldn’t cost the Earth.
