• Patented TPA Filtration Destroys 99.9% of Particles: Patented TPA Active Filtration: A high‑pressure ion filter that destroys harmful particles instead of merely trapping them. Our washable TPA filter captures 99.9% of particles down to 0.0146 μm—over 20× more effective than HEPA (0.3 μm). Experience true air purification for easier breathing and relief from allergens and asthma triggers.
• Lifetime Washable Filter: Eco & Cost Friendly: Unlike standard HEPA filters, our patented TPA filter is washable and reusable, making it more sustainable and affordable over time. While HEPA filters are made from plastic, the washable filter of the X3 air purifier is made from Graphene, which is more durable and recyclable. The Airdog air cleaner is eco-friendly and saves on the maintenance cost of the HEPA filters year by year.
• Purifies 942 ft² /hr with 360° Airflow: The air purifier with washable filter is perfect for bedrooms and small-to-medium rooms. Its 360° air intake purifies up to 942 ft² (87 m²) per hour (CADR 120 CFM/204 m³/h). Third-party tested, it destroys 99.9% of particles down to 0.0146 μm, eliminating dust, pet dander, pollen, allergens, smoke, odors, TVOCs, and formaldehyde.
• Real‑Time AQI Sensor with Smart Auto Mode: With the built-in air quality sensor, the Airdog X3 air purifier can read the real-time AQI (Air Quality Index) and reflect it with its indicator light. (Green: Excellent: AQI≤50, Yellow Green: Good: 50＜AQI≤100, Yellow: Moderately Polluted: 100＜AQI≤150, Red: Hazardous: AQI＞150.) The Auto Mode allows the Airdog air purifier to adjust wind speed according to the AQI, ensuring purification efficiency and reducing energy consumption.
• Whisper‑Quiet 22 dB Sleep Mode for Undisturbed Rest: Our Airdog X3 ionic air purifier uses a vertical tray design to resist clogging and cut noise—even after prolonged use. It offers 4 purification speeds and two modes (Auto and Sleep) to suit any environment. In Sleep mode, the X3 runs at just 22 dB—quieter than a whisper—so you can enjoy fresh, clean air all night without disturbance.
