Dyson launches new purifier range

Dyson formaldehyde

The Dyson HEPA Cool Formaldehyde integrates solid-state formaldehyde sensors and sealed HEPA 13 standard filtration.

The new range is also 20 percent quieter than previous models.

It’s designed to tackle indoor pollution. Conventional ventilation, air circulation and air-conditioning systems may not have adequate HEPA filtration. Dyson’s latest purifiers are engineered to provide high-quality filtration and powerful projection to support existing HVAC (heating, ventilation and air-conditioning) systems and provide cleaner, purified air.

Dyson re-engineered the machine airflow pathways to achieve sealed HEPA 13 standard filtration, according to a product release. This not only ensures no air bypasses the filter, but also blocks any potential leak points through which dirty air may enter the air flow. A solid-state formaldehyde sensor works alongside Dyson’s unique algorithm to precisely monitor formaldehyde levels – ignoring other gases, which are detected by a dedicated VOC (volatile organic compound) sensor.

Formaldehyde is a colourless gas pollutant released by furniture and wooden products that use formaldehyde-based resins. Thus, it is common in new or refurbished spaces. Formaldehyde is 500 times smaller than 0.1 microns, making it particularly difficult to capture, but it leads to long-term exposure if left undetected due to off-gassing.

Formaldehyde sensors can be gel-based and may deteriorate gradually as they dry out over time. Using a solid electro-chemical cell, the Dyson formaldehyde sensor doesn’t not dry out and its unique algorithm cross-checks data every second, selectively sensing to avoid confusion with over VOCs.

Dyson’s selective catalytic oxidation (SCO) filter continuously destroys formaldehyde at a molecular level. The catalytic filter has a unique coating, with the same structure as the Cryptomelane mineral. Its billions of atom-sized tunnels are the optimal size and shape to trap and destroy formaldehyde, breaking it down into tiny amounts of water and carbon dioxide. It then regenerates from oxygen in the air to keep destroying it continuously without ever requiring replacement.

Other features include:

  • tested in Dyson’s Malaysia Development Centre’s acoustics chamber and re-engineered to be 20 percent quieter
  • Dyson Link App and voice control activation help avoid touch points and possible contamination, and
  • Dyson Air Multiplier Technology helps the machine project purified air to every corner of the room.

Available this May, the Dyson HEPA Cool Formaldehyde is designed for businesses and commercial spaces, with other benefits including longer cable, an additional one-year warranty and a spare remote control.
