【Double-sided Air Inlets Design & Compact yet Powerful】LUNINO air purifier features an innovative dual-side air intake design, purifying air simultaneously from both sides, resulting in a 40% faster purification speed compared to single-side intake models. Despite its compact size, this dual-filter air purifier boasts powerful purification capabilities. Suitable for large rooms up to 2800 ft² while consuming only 18W of power, ideal for living room, office, bedroom, dormitory, pet area, basement, kitchen, children’s room. 【Intelligent Connectivity & Real-time Sensing】Through the Tuya app (compatible with Alexa/Google voice control), users can schedule operations, enable automation, and remotely control the air purifier with app—like turning it on high speed before you arrive home. The smart air purifier features a PM2.5 particulate sensor with a color-coded real-time air quality indicator (Green/Orange/Red) and an auto mode that adjusts the fan based on real-time readings. (Auto mode is toggled by a long-press of the power button.) 【High Efficiency HEPA Air Filter & Washable Pre-Filter】The true HEPA air purifier uses a 3-stage filtration system (washable pre-filter + HEPA filter) to capture 99.97% of fine particles as small as 0.3 microns, including pet dander, smoke, and odors. It is effective for sensitive households. The washable pre-filter (the white filter on the machine’s cover) should be cleaned monthly. Regular maintenance ensures peak performance, extends the HEPA filter’s lifespan, reduces replacement needs, and improves long-term efficiency. 【2-in-1 Purifier+ Fan&Quiet Operation Every Season】This 2-in-1 air purifier and fan features three adjustable airflow angles (30°/60°/90°), providing both purification and air circulation for comfort in any season. In Sleep Mode, the quiet air purifier runs at a near-silent 15dB with dimmed indicators and lights off, delivering fresh air throughout the night without disturbing light sleepers. 【Filter Replacement Reminder】The home air purifiers have a filter replacement reminder function. When the filter reaches the end of its service life, the indicator light will light up to remind you that it needs replacing. Please use official LUNINO replacement filters to ensure optimal performance. (The official replacement filter can be purchased on Amazon by searching B0DSBS5LHQ.) 【Reliable After-sales Support】ETL/FCC/CARB Certified, LUNINO provides more than 1-year warranty and lifetime technical support for this air purifier.
