[Dual-Side Filtration for Homes with Pets]Engineered with dual side air intake technology, this pet air purifier efficiently captures pet hair, dander, and odors through a HEPA filtration system. It cleans air in spaces up to 2400 sq. ft., working twice as fast as single-inlet models. It captures over 99.9% of airborne particles, including dust and pet hair, allowing you and your furry friend to enjoy a comfortable home environment.[99.9% HEPA Filter: High Efficiency & Magnetic Design]The HEPA air purifier features 360° circulation and dual air intake, effectively filtering 99.9% of particles as small as 0.1 microns. Compared to single air inlet systems, it delivers greater efficiency and captures more impurities. The magnetic design allows for effortless filter replacement-simply remove and insert the new one within seconds, no tools required. Built-in reminders alert you when it's time to change the filter (with a 6â8 month lifespan under 12 hours of daily use). For best performance, vacuum the filter regularly to extend its service life.[Sleep Mode with 15dB Ultra-Quiet & Operation]Ideal for light sleepers, this bedroom air purifier operates at a whisper-quiet 15dB in sleep mode-quieter than rustling leaves-while consuming minimal power. The display dims completely, leaving only a subtle sleep icon, and the fan speed adjusts to balance purification and energy efficiency. Perfect for nurseries or noise-sensitive environments, it ensures fresh, clean air while you rest undisturbed.[Smart App Control & Air Quality Sensor]Control this HEPA air purifier from your smartphone via the app: set a 1-12 hour timer, switch between sleep, auto, and manual modes, and track filter life. You can activate sleep mode from bed for quiet, gentle purification. Equipped with a real-time PM2.5 sensor that updates every 0.1 seconds, the purifier displays air quality via a color-coded light (e.g., red for poor air quality). It automatically adjusts fan speed based on pollution levels for optimal performance.[3 Fan Speeds, 12-Hour Timer & Suitable for All Spaces]Customize airflow with 3 adjustable fan speeds. The air purifier boosts intake efficiency at higher speeds, and the 12-hour timer fits seamlessly into your schedule. Suitable for various living spaces such as bedrooms, living rooms, offices, dorms, basements, or kitchens, this HEPA filter adapts easily to any room size.[Real-Time Air Quality Display & Smart Auto Mode]: The built-in PM2.5 sensor continuously monitors air quality and clearly displays the results on the screen. In Auto Mode, the fan speed adjusts automatically based on detected air quality to ensure optimal purification performance.
