This pet air purifier features dual-side air intake technology and a HEPA filtration system, effectively capturing pet hair, dander, and odors, covering an area of up to 2400 square feet.

The magnetic filter design allows for instant replacement and includes a filter replacement reminder (approximately every 6-8 months with 12 hours of daily use). In sleep mode, it operates at a low noise level of 15 decibels, with the panel light off, making it suitable for use in nurseries or bedrooms at night. It supports smart app control, allowing users to set a 1-12 hour timer, switch between sleep/auto/manual modes, and monitor air quality every 0.1 seconds using a real-time PM2.5 sensor, displaying the pollution level via color indicator lights. The auto mode adjusts the fan speed according to the pollution level, with three adjustable fan speeds.
