About this item
Dyson's latest purifiers combine intelligent sensing with an advanced filtration system. Three phases of purification sit within a fully sealed filtration and airflow system. So what goes inside, stays inside. A solid-state formaldehyde sensor and a unique catalytic filter detect and continuously destroy formaldehyde¹, an activated carbon filter removes gases and odors and a HEPA filter captures 99.97% of particles 0.3 microns in size. Then powerful Air Multiplier technology purifies, heats the whole room and cools you.²

Q: QuestionDoes it have any plastic part? Does it have a California Proposition 65 warning?(2 answers)
A: AnswerHello Gedys, this is Kelly with Dyson. There are plastic components within the Dyson Purifier Hot+Cool Formaldehyde HP09. Prior to 2019, Dyson made the decision to redesign our machines so that a Prop 65 label is no longer needed. Therefore, all Dyson products produced in 2019 and later do not require the prop 65 label. To provide you with additional confidence in our products, in 2018 Dyson developed a new comprehensive Prop65 assessment program in collaboration with 3rd Party laboratories. The assessment included full product evaluation & testing on high risk parts/materials and a toxicological risk assessment process by US board-certified toxicologists to evaluate the chemicals identified in our finished product. Only after passing the assessment, are the products made available for sale. We hope this puts your mind at ease and removes any reservations about the use of our machines. Best Wishes, Kelly Dyson Customer SupportAnswered by DysonProductExpert

Q: QuestionDoes this unit release ozone when in use?(2 answers)
A: AnswerHello MM, this is Kelly with Dyson. Typically, purifiers utilize an ionizer which releases charged chemicals into the air, which bond with particulates and assist in removing those particles. However, this generates Ozone in the home. Dyson purifiers do not use ionization to purify the air and do not generate any ozone. Best Wishes, Kelly Dyson Customer SupportAnswered by DysonProductExpert
- A: AnswerHi there, this is Kelly with Dyson, and this is a fantastic question. Our current Hot+Cool products do not contain Teflon/PTFE as a part of the heating element. We hope this helps! Best wishes, Kelly Dyson Customer Support
Answered by DysonProductExpert
- A: AnswerHi there Sparky, this is Tia from Dyson. What you have described is the continuous monitoring option which is used for air quality, temperature and humidity data and is relayed to the machine and app at all times, even when you have turned the purifier off. The sensors have small fans that maintain airflow for continuous monitoring, but this should not cause any audible noise interference. To control this feature, press and hold the Auto mode button on the remote control for 5 seconds to turn it on. The LCD screen will indicate when continuous monitoring is on or off. Thanks for your support of Dyson technology! Best wishes, Tia Dyson Customer Support
