Dyson Big+Quiet Formaldehyde Purifier - Prussian Blue & Gold

The quietest, most powerful and advanced air purifier. Purifies large spaces and projects air over 32 feet. And cools you in warmer weather.

- Engineered to purify large spaces: Fully-sealed to HEPA H13 standard to capture 99.95% of pollutants as small as 0.1 microns.4 Purifying rooms up to 100m², evenly - Acoustically engineered: The Helmholtz silencer traps sound energy and reduces low frequency noise, while the motor mount reduces vibration full power. so the little noise you hear, is quiet even at - Powerful and quiet: The high-velocity, low-pressure system produces low noise levels of just 55.6dB - Senses and reports CO2 levels: 1.44 inch LCD screen displays carbon dioxide readings and airflow mode – senses and reports air quality levels in real time - The filtration system within the Dyson purifier: Whole-machine HEPA 13 filtration. Three phases of purification draw pollutants in from all directions. And the whole machine is fully sealed to HEPA H13 standard – so what goes in, stays in - A formaldehyde molecule: Destroys formaldehyde, continuously. The solid-state formaldehyde sensor works simultaneously with a selective catalytic oxidisation filter, to destroy formaldehyde molecules 500x smaller than 0.1 microns - HEPA filter: The HEPA filters contain 21 metres of borosilicate microfibres, pleated over 450 times, and lasts 21,900 hours - Activated carbon filter: 430,000m² of activated carbon captures microscopic particles, and lasts 8,760 hours - Single button operation: Two airflow speeds to increase or decrease airflow when needed
