Dyson Purifier Humidify & Cool Formaldehyde – PH04

The HEPA filter captures 99.97% of particles 0.3 microns in size. A layer of activated carbon also removes odors and gases including VOCs.

Automatically Purifies And Hygienically Humidifies for a Healthier, More Comfortable Environment

The latest Dyson purifier humidifier is engineered to help improve your air quality. Dyson’s most advanced filtration system combines a precise, solid-state formaldehyde sensor with a unique catalytic filter that continuously destroys formaldehyde.¹ An activated carbon filter removes gases and odors and a HEPA filter captures 99.97% of particles 0.3 microns in size. And powerful Air Multiplier™ technology projects purified, humidified air throughout the room.

Helpful Tips about Humidifying Your Air

Dyson purifier humidifiers let you achieve your desired humidity either automatically or manually. In Auto mode, just set it and forget it. In manual mode, the LCD indicates if you need to increase airflow which may help you reach your target quicker. And remember, this machine is engineered to purify and humidify single rooms, and works most efficiently in a sealed environment.

Senses and Reports, Automatically

Integrated sensors constantly analyze 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 0.3 microns in size. A layer of activated carbon also removes odors and gases including VOCs.

Destroys Formaldehyde, Continuously

Household items like wood flooring and fabric can release formaldehyde for years. The Dyson catalytic filter traps and breaks down formaldehyde molecules into water and CO2. And it never needs replacing.

Precisely Detects Formaldehyde

A lifetime solid-state sensor detects formaldehyde molecules – 500 times smaller than 0.1 microns.

Destroys Potentially Harmful Bacteria

Dyson Ultraviolet Cleanse technology exposes every drop of water to a UV light, removing 99.9% of bacteria in the water, to hygienically humidify.

Fully Sealed to HEPA H13 Standard

To prevent pollutants leaking back into the air, it’s not just the filter that’s sealed to HEPA H13 standard, it’s the whole machine. So what goes inside, stays inside.

Circulates Purified Humidified Air

Dyson Air Multiplier technology mixes and circulates purified, humidified air throughout the room.

Cools You When Needed

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

Auto Mode

Constantly monitors your air quality, automatically adjusting airflow to reach and maintain the most comfortable humidity level and react to pollution events.

Continuous Humidification

An efficient water management system and a one gallon tank give you up to 36 hours of hygienic humidification without regular refilling.

Deep Clean Cycle

Activate the machine’s monthly hassle-free Deep clean cycle at the touch of a button. It will guide you through the simple step-by-step process.

Simple Filter Changes

Built-in reminders show you when your combination filter needs changing. It’s quick and easy to do.

App Control

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

Voice Control

Control it hands-free with compatible voice services including Amazon Alexa, Siri and Google Assistant.

Night Mode

Purifies using the quietest settings and a dimmed display. Sleep timer enables pre-set intervals of use, between 15 minutes and 9 hours.

Jet Axis Control

Two oscillators guide the airflow – projecting separately, or in unison, so you can choose different airflow modes.

Breeze Mode

Unique algorithms vary the airflow to mimic a cooling, refreshing breeze.

Backward Airflow Mode

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

Certified Asthma and Allergy Friendly

Dyson purifiers are certified asthma and allergy friendly by the Asthma and Allergy Foundation of America.
