While much focus on clean air centres around outside pollutants, you’d be surprised to discover the quality of the air indoors. From pollen entering your home to harsh chemicals in cleaning products, the air quality in your home can be rather unhealthy. This is where an air purifier such as the Dyson Pure Cool Tower comes in.

Designed as both a regular fan and an air purifier, this is Dyson’s second-generation air-cleaner. Improvements over the original Pure Cool Link include a more detailed display, showing you the level of pollutants in your home, and a purifier-only mode that stops cold air being blown at you.

The Dyson Pure Cool Tower uses Dyson’s now-distinctive bladeless design. It remains as impressive today as it did at launch. Dyson’s Air Multiplier technology directs airflow up and through the thin blade around the outside edge of the fan, creating a smoother blast of air.
