Details
𝐀𝐇𝐀𝐌 𝐕𝐞𝐫𝐢𝐟𝐢𝐞𝐝 & 𝐇𝐢𝐠𝐡 𝐂𝐀𝐃𝐑 𝐕𝐚𝐥𝐮𝐞: 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 m³/h) and a Pollen CADR of 244 CFM (415 m³/h). AHAM certification guarantees effective, high-speed air purification for your home.
𝐄𝐟𝐟𝐢𝐜𝐢𝐞𝐧𝐭 𝐀𝐢𝐫𝐟𝐥𝐨𝐰 𝐃𝐞𝐬𝐢𝐠𝐧: 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 ft², reaching up to 80% purification efficiency, while still delivering 1 full air refresh per hour in larger spaces up to 1695 ft² with about 45% efficiency, helping maintain cleaner, fresher air throughout your home.
𝐃𝐮𝐚𝐥 𝐅𝐢𝐥𝐭𝐞𝐫𝐬 & 𝟑-𝐒𝐭𝐚𝐠𝐞 𝐃𝐞𝐬𝐢𝐠𝐧: 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 & 𝐄𝐂𝐎 𝐌𝐨𝐝𝐞𝐬: 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.
𝐌𝐮𝐥𝐭𝐢𝐩𝐥𝐞 𝐌𝐨𝐝𝐞𝐬 & 𝐅𝐚𝐧 𝐒𝐩𝐞𝐞𝐝𝐬: 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.
𝐑𝐞𝐚𝐥-𝐓𝐢𝐦𝐞 𝐀𝐢𝐫 𝐐𝐮𝐚𝐥𝐢𝐭𝐲 𝐃𝐢𝐬𝐩𝐥𝐚𝐲: 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.
𝐇𝐚𝐬𝐬𝐥𝐞-𝐅𝐫𝐞𝐞 𝐌𝐚𝐢𝐧𝐭𝐞𝐧𝐚𝐧𝐜𝐞: 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).
