SingaporeDyson is a technology company founded in the United Kingdom in 1991 and headquartered in Singapore since 2019, known for bagless vacuum cleaners, bladeless fans, hair care and air treatment products. Its purifiers seal the whole machine to HEPA H13 standard and pair a solid-state formaldehyde sensor with a catalytic filter that destroys formaldehyde instead of trapping it. Readings for particles and gases appear on the on-board LCD and in the MyDyson app, with Amazon Alexa and Google Home support.
