Dyson has announced a new air purifier and fan model that adjusts its settings based on the ambient environment.

The Pure Cool Link tower replaces the previous purifier and fan model and includes sensors that monitor the air quality surrounding the unit.

The device is then able to automatically adjust its settings based on changes in the air quality.

The Pure Cool Link also has an automatic night-time mode that dims the unit’s LEDs and reduces the fan speed to minimise interruption to the user’s sleep.

A companion smartphone app for iOS and Android allows owners to check on indoor and outdoor air quality and modify settings remotely. An analogue remote is also provided as a control alternative.

Air filtering duties are handled by a 360 degree Glass HEPA filter, which is capable of removing 99.95 percent of allergens and pollutants of sizes as small as 0.1 microns, the company said.

According to Dyson, the Pure Cool Link "will be available in Australia later this year", but no price has been set.
