Product Overview

Dyson Purifier Hot+Cool Formaldehyde HP09 is a flagship air purifier that doubles as an air heater. As its name suggests, the HP09 features Dyson's proprietary formaldehyde-capture technology.
Naturally, the Purifier Hot+Cool Formaldehyde features the company's 360˚ sealed filter with HEPA and activated carbon filters that are able to remove harmful gases and capture 99.97% of particles down to 0.3 microns.
Its formaldehyde capture panel, debuted last year with the PH02 Humidify+Cool, features billions of microscopic tunnels that trap and destroy formaldehyde, breaking it down to water and CO2.
As usual, the device continually monitors the quality of the air with its range of sensors to adapt its program automatically.
The HP09 is able to oscillate at 350-degrees angle and features Night mode that is quieter and gentler.
For those who do not need the formaldehyde-destroying feature, Dyson also markets the HP07.

Reviewer score 85% (normalized by Neofiliac)
Reviewers from techradar have found:
The Dyson HP09 detects and traps formaldehyde in its catalytic filter, which then breaks it down into tiny amounts of water and CO2 that are released back into the air. The base houses two filters: one for formaldehyde and the HEPA H13 filter that Dyson says captures 99.95% of dust and allergen particles as small as 0.1 microns. The purifier can be controlled via the compact remote, which allows adjustment of the temperature, speed and setting a timer.
Pros
  • Works with Alexa, Google Assistant and Apple HomeKit
  • Easy to set up and use
Cons
  • Doesn’t work with Alexa or Google Assistant
