Airdog X3 Home Air Purifier with Washable Filter: Patented TPA filtration technology up to 20X more effective than HEPA
For families managing allergies or pet dander, the Airdog X3 Home Air Purifier offers more than just cleaner air—it provides a break from the constant worry about indoor air quality. While most air purifiers focus on basic filtration, this device delivers peace of mind by tackling particles so small they often slip through other systems, like the lingering smoke after cooking or microscopic allergens that trigger sneezes.
Its patented TPA technology captures 99.9% of particles down to 0.0146μm, making it up to 20 times more effective than standard HEPA filters. You will notice the difference within minutes as it cleans rooms up to 942 square feet per hour, quietly removing odors and irritants without the hassle of filter replacements. The washable filter saves you from yearly costs and waste, while the real-time AQI display and auto modes adjust fan speed to keep your air fresh effortlessly. In sleep mode, it runs at just 22dB, so silent you might forget it is there, ensuring restful nights for you and your loved ones.
