How to use your purifier
Understanding the LCD screen icons
The icons on your LCD screen show which pollutants are present, reporting in real time. The icons also tell you about temperature, humidity and filter life.
Indoor Air Quality Index (AQI)
Shows your air quality over the last 12 seconds, or over the last 24 hours.
Particulate matter PM2.5
Shows microscopic particles smaller than 2.5 microns, including smoke, bacteria and allergens.
Particulate matter PM10
Shows particles smaller than 10 microns, including pollen, dust and pet dander.
Volatile Organic Compounds (VOCs)
Shows gases released from a wide range of sources, such as aerosol sprays and air fresheners. They include benzene, household fumes and odors.
Nitrogen Dioxide (NO₂)
Shows oxidizing gases such as NO₂, released by combustion. Includes cigarette smoke, car emissions, candles and gas stoves.
Shows how much filter life remains on the combination filter. So you know when to replace it.
Understanding pollutant levels
When a pollutant reduces your air quality, its icon appears on screen. In this case, PM10. The colored bar on the left indicates how much of the pollutant is present, and will continually update as the machine purifies your air.
When the green section of the colored bar is highlighted, your purifier is detecting a very low level of the type of pollutant.
When the yellow section of the colored bar is highlighted, your purifier is detecting a moderate level of the type of pollutant.
When the orange section of the colored bar is highlighted, your purifier is detecting a high level of the type of pollutant.
When the red section of the colored bar is highlighted, your purifier is detecting a very high level of the type of pollutant.
Using the remote control
Maintaining your purifier
To ensure optimum air purification performance, we recommend replacing your HEPA+Carbon filter every 12 months.
Frequently asked questions
Increasing airflow will create a cooling effect using purified air, so you may find it beneficial to change your purifier's speed settings as the temperature changes. For personal cooling, use settings 4-10. In colder periods, enable Backwards airflow mode. It projects air through the back of the machine, to avoid unwanted cooling.
If you're concerned by the brightness of your purifier's LCD display, consider enabling Night-time mode using your remote control. During operation, a small moon icon indicates that your purifier is on, but the main display turns off after 10 seconds to help avoid sleep disturbance.
If auto mode is enabled, AUTO will be illuminated on your purifier's LCD display. When your machine is purifying the air, AUTO will be in white. When the air in the room is purified, it will turn green and your purifier will remain idle until pollutant levels rise.
Your purifier's auto mode is designed to manage the air quality in your home without you having to operate the machine – so it's only on when it needs to be. If you or someone in your home suffers from allergies or respiratory illnesses, we particularly recommend using your machine's auto mode.
Your purifier is engineered to purify single rooms, so you should use it where you spend the majority of your time at home. When placing the machine, make sure there is at least a few feet of clearance on all sides so that the air can circulate effectively.
Your purifier works most efficiently in a sealed environment – opening the windows can allow more pollutants to enter the air in your home, which means your machine will take longer to work.
