Dyson Business Case Study

Engineered to purify large spaces, with performance and wellbeing in mind. The Dyson HEPA Big + Quiet Formaldehyde purifying fan creates a cleaner, more comfortable working environment.

It’s Dyson Business to Understand Air Pollution, So Yours Doesn’t Suffer

Workspaces can harbour pollutants such as viruses, bacteria, Volatile Organic Compounds (VOCs), pollen and formaldehyde. Everyday items such as cleaning products and printers, furniture and flooring, can release potentially harmful microscopic particles, and remain in the air for many years.[3]

Dyson Purifiers Remove These Common Pollutants From Commercial Environments

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 100m[2], evenly.[1]

Senses, Captures and Destroys

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.

Whole-Machine HEPA 13 Filtration[2]

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.

Destroys Formaldehyde, Continuously[3]

The solid-state formaldehyde sensor works simultaneously with a selective catalytic oxidisation filter, to destroy formaldehyde molecules 500x smaller than 0.1 microns.

Powerful and Quiet

The high-velocity, low-pressure system produces low noise levels of just 55.6dB.

Acoustically Engineered

The Helmholtz silencer traps sound energy and reduces low frequency noise, while the motor mount reduces vibration – so the little noise you hear, is quiet even at full power.

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.

What’s in the Box:

• Activated carbon filter
• HEPA filter

Notes

• 1. Test completed in a 100 m2/1000ft2 (12.7m x 7.9m) room with the purifier placed in one corner and source of pollution in opposite corner. The room had 36 sensors to determine PM2.5 distribution and purification. Results may vary in practice.
• 2. Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.95%.
• 3. Third party full machine testing based on GB/T 18801-2022 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.
• 4. Tested for filtration efficiency at 0.1 microns (EN1822, ISO29364).

Product Features:
