KNKA APH4000
If you're a pet owner who has ever walked into a room and smelled the evidence of your furry friend's presence, the KNKA APH4000 is designed for you. This air purifier tackles pet odors and dander head-on with a dedicated Pet Mode that boosts airflow to refresh a room in just 30 minutes. The dual front-and-back intake pulls in air from both sides, capturing hair and particles before they settle.
What sets this unit apart is how it balances power with quiet operation. In Sleep Mode, it runs at only 22-24 dB, so it won't disturb your lightest sleepers. The real-time AQI display and color-coded lights let you know your air quality at a glance, and the ECO Mode automatically stands by when the air is clean, saving energy and extending filter life. With a CADR of 244 CFM for pollen, it's AHAM Verified, meaning it performs as promised. The washable pre-filter cuts down on maintenance, and the filter replacement indicator ensures you never forget when it's time for a change. For whole-home coverage up to 1,695 ft², this is a smart, practical choice for breathing easier.
