Q: Does this model, BP03, have a heat/cool temperature control function?
A: Hi there, this is Jenifer with Dyson. The Dyson Purifier Big + Quiet Formaldehyde BP03 quietly purifies large spaces while it detects and destroys formaldehyde, permanently. It removes gases and odors. This model does not feature a heat function. Our purifiers and fans do not have refrigerants, so they are not an air conditioner but do work better than standard fans. Dyson fans use Air Multiplier technology to create a powerful stream of uninterrupted airflow. Air is accelerated through an annular aperture, creating a high-velocity jet of air. This passes over an air foil-shaped ramp, channeling its direction and creating areas of low pressure behind and around the fan. The change in pressure forces surrounding air to be drawn into the airflow, resulting in a powerful stream of smooth cooling air. Please feel free to email us at [email protected] with any additional questions as we are happy to provide you with support. Best wishes, Jenifer Voice of the Customer
Q: what does Quiet Formaldehyde mean?

Giving you reassurance that what goes inside, stays inside. It auto detects and destroys the harmful Formaldehyde fumes present in the air.
