Condition: NEW- Functional?: Yes Missing Parts?: No UPC: 769016330562 ASIN: B0FNDG2TNK Color: White Certified by the Association of Home Appliance Manufacturers, this air purifier provides reliable performance with a Smoke/Dust/PM2.5 CADR of 226 CFM (384 m /h) and a Pollen CADR of 244 CFM (415 m /h). AHAM certification ensures effective, high-speed air purification for your home. Engineered with dual front-and-back air intakes and dual side outlets, this purifier maximizes circulation for faster air exchange. It refreshes the air 4.8 times per hour in rooms up to 350 ft , reaching up to 80% purification efficiency, while still delivering 1 full air refresh per hour in larger spaces up to 1695 ft with about 45% efficiency, helping maintain cleaner, fresher air throughout your home. Equipped with dual front-and-back cartridges, each featuring a three-stage filtration system: a washable pre-filter for larger particles, a High-Efficiency filter, and an activated carbon filter. 3-in-1 filter system traps everything from pet hair to microscopic particles, ensuring thorough purification. (Please remove the filter's plastic packaging before installation.) PET Mode increases airflow to tackle pet hair, dander, and odors, refreshing the air in just 30 minutes. ECO Mode saves energy and extends filter lifespan by entering standby when air quality is excellent, then restarting automatically when purification is required. Includes Sleep Mode with noise levels as low as 22-24 dB for ultra-quiet nights, Auto Mode for effortless adjustments, and four fan speeds for personalized comfort. Select the setting that suits your needs any time of day. A built-in sensor monitors indoor air and displays the AQI in real time. Color-coded lights make it easy to check your air quality in an instant. The filter replacement indicator notifies you when it's time for a change. For optimal performance, replace the filters every 3 6 months. Use genuine KNKA filters (search B0FQNYGVZF, B0GCMV5JGF or B0GCNPGMYM on Amazon).
