Key features

• •2020 ULTIMATE DESIGN: The AGH550 has a CADR rating of 324 CFM, making it best for large spaces around 750 sq ft. In a 30'x25' open floor plan on high speed, the air will be completely circulated and refreshed in less than 19 minutes, or more than 3 times per hour.
• •TRUE HEPA FILTER: Originally designed for the US Army, HEPA filters are the gold standard of residential air purification by filtering out 99.97% of airborne particles 0.1 microns or larger. Human hair has a diameter of 50 microns, which is 166 times larger than airborne particles removed by your purifier.
• •SILENT OPERATION: Tired of lying in bed at night listening to the hum of your air purifier? No more! The max operating noise in sleep mode is only 25 decibels making the AGH550 quieter than a whisper or rustling leaves on a crisp fall day.
• •REAL-TIME MONITORING: The AGH550 has a PM2.5 laser sensor that uses a laser beam to count and determine the size of airborne particles, resulting in cleaner air and efficient operation. Traditional air purifiers use cheap infrared sensors, which can give a quick good/bad overview of air quality but can't count or determine the size of particles, leading to inaccurate air quality readings.
• •ENERGY SAVING: The AGH550 is rated at 40W. If ran 24/7/365 your air purifier would use about 350 kWh of power per year. Multiply 350 times your local energy cost per kWh (US average: $0.12/kWh) to get the total yearly cost to run your purifier, which should be around $45. Clean air can be yours for less than 12 cents per day!
