Captures gases and ultra fine particles
The sealed filtration system combines an activates
carbon filter to remove gases and a sealed HEPA
filter to capture 99.95% of ultra fine particles.
PH01 machine comes with Combination filters.
PH02 comes with permanent Cryptomic filters
and Combination filters.
Anti-bacterial evaporator
Silver strands are woven into 3D air mesh of 6mm
intervals.
They help prevent bacteria from growing on the
evaporator.
Reflective PTEE tube
Made from a highly reflective material. It
mirrors UV light up and down the tube, to
kill bacteria.
Sensor detects and display pollutants and humidity levels
A unique algorithm processes input from each sensor and
activates the machine, to capture pollutants, humidity, and
project cleaner air.
Destroys potentially harmful bacteria
Dyson Ultraviolet Cleanse technology exposes
every drop of water to an ultraviolet light. This
kills 99.9% of bacteria.
The UI screen shows different error icons according to the machine’s status. Many of these are temporary
or can be corrected by carring out a hard reset and/or a software update. To hard reset, switch off the
machine and unplug the mains supply for 20 secs, then plug the machine back in and switch it back on.

PH01 and PH02 have a ‘self cleaning’ cycle built in. This is to reduce limescale build up. In
normal use the machine will show an alert when it needs to carry out a Deep clean cycle.
If connected to the Dyson Link app, you will receive a notification message. If not using the
Dyson Link App, the LCD screen on the machine will alert you and the Deep clean cycle
button will light up. To cancel the Deep clean cycle at any point, press and hold the Deep
clean cycle button for five seconds.
Important: do not turn off or unplug the machine as the cleaning instructions will appear
on the LCD screen.
Press the Deep clean cycle button on
the front of your machine and your
instructions will be shown on the LCD
screen.
Remove the evaporator
from your
machine, place it in the
water tank
and refit the cap.
Carry the water tank by its
handle to the tap.
Remove the cap and

Electrical safety testing
Insulation test points:
Test directly onto the eight T-10 screws in the Main body.
Note: the filters will need to be removed to gain access to the screws.
These tests are vital to avoid any possibility of personal injury to the end user.
Tests should be performed using the 500 volt DC setting of a locally compliant insulation tester.
The following tests must be performed prior to and upon completion of all repairs to Dyson
