DYSON OFFICIAL OUTLET - HP09 Hot+Cool Formaldehyde Air Purifier - Refurbished with 1 year Warranty (Excellent)

Description

Our latest purifier detects and destroys formaldehyde, continuously

It combines a precise solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde.

HEPA and activated carbon filters also capture dust, allergens, gases² and other pollutants.

And Dyson purifiers have powerful Air Multiplier™ technology to purify the whole room.³

Senses and reports, automatically

Integrated sensors constantly analyse your air, while our unique algorithm cross-checks data every second. It diagnoses pollutants at a molecular level, displaying live results on the LCD.

Captures gases and ultrafine particles

The HEPA filter captures 99.97% of particles as small as 0.3 microns. A layer of activated carbon also removes odours and gases including VOCs.²  

Destroys formaldehyde, continuously

The Dyson catalytic filter continuously traps and breaks down formaldehyde¹ molecules into water and CO2. And it never needs replacing.

Purifies the whole room³

Dyson purifiers have Air Multiplier™ technology. It generates the circulation power to draw even distant pollutants into the machine, projecting purified air throughout the room.³

Fully sealed to HEPA H13⁴

In our latest purifiers, it's not just the filter that meets HEPA H13 standard, it's the whole machine.⁴ So what goes inside, stays inside.

Precisely detects formaldehyde

Our latest purifiers use a solid-state sensor to detect formaldehyde molecules – 500 times smaller than 0.1 microns. Maintains precision for the lifetime of the machine.

Heats in winter

With long-range projection, it’s quick to heat the whole room evenly.³

Cools you in summer

In warmer weather, a powerful stream of purified airflow can cool⁷ you down.

Backward airflow mode

Diverts airflow through the back of the machine. To purify, without cooling you.

App control

Control and monitor your air quality from anywhere using the Dyson Link app.⁵

Oscillates up to 350 ̊

Adjustable oscillation projects purified air around the whole room.

Voice control

Control it hands-free with compatible voice services.⁶

Night mode

For lighter sleepers. Monitors and purifies using the quietest settings, along with a dimmed display.

Easy filter care

The filter is quick and easy to change. With automatic filter-life notifications on the LCD or Dyson Link app.⁵

¹ Third party full machine testing based on GB/T 18801-2015 formaldehyde cumulative clean mass testing with continuous injection until plateau of formaldehyde CADR is achieved. Results may vary in practice.

² Gas capture rates may vary.

³ Tested for air projection (DTM801), purification coverage in a 2860ft³ room (TM-003711), and heating performance in a 1236ft³ room (DTM961).

⁴ Particle challenge by DEHS oil specified in EN1822 within a chamber specified in ASTM F3150. Tested in Max Mode at IBR US, for whole machine efficiency above 99.97%.

⁵ Requires device to run app, Wi-Fi or mobile data, Bluetooth 4.0 support, and iOS version 10 or Android version 5 (or above). Standard data and messaging rates may apply. App control doesn’t apply to heating. 

⁶ Refer to the Dyson Link app for compatible voice services.

Quality refurbished by Dyson with a 1 year Dyson warranty

Note: Colour may vary

Dyson refurbished machines are different. Each machine has passed a detailed inspection and hundreds of tests, to meet the same standards as a new machine. Units may have some minor cosmetic blemishes that do not affect functionality. So when Dyson say they're 'like new', they mean it.
