KNKA Air Purifiers for Home Bedroom Up to 1,695 Ft² in 1 Hr, APH4000, Black

About this item

The KNKA APH4000 is a black AHAM-certified air purifier built for bedrooms and larger living areas. Its dual-intake design pulls air from front and back, running through two 3-stage filter cartridges (pre-filter, HEPA-type, and carbon) to remove dust, pet hair and odors. It reads air quality in real time, adjusts automatically, and switches to a near-silent 22-24 dB Sleep Mode at night.

• AHAM-certified with CADR of 226 CFM (384 m³/h) for smoke/dust/PM2.5 and 244 CFM (415 m³/h) for pollen
• Dual front-and-back intakes with side outlets clean air 4.8x/hour in rooms up to 350 ft², or once per hour in spaces up to 1,695 ft²
• Two 3-stage filter cartridges (washable pre-filter, HEPA-type filter, activated carbon) catch pet hair, dust and fine particles
• PET Mode boosts airflow for pet hair and odors in 30 minutes; ECO Mode auto-pauses when air is clean to save energy and filter life
• 4 fan speeds plus Auto and Sleep Mode (22-24 dB) for quiet nighttime use
• Real-time AQI display with color-coded lights, plus a filter-change reminder (replace every 3-6 months, model APH4000)
