The P340 is an intuitive and sleek air purifier, that improves the air quality through multi-stage filtration and clean air technologies (pre-filter, true HEPA, activated carbon and integrated ioniser). This unit is effective in combating pollen, dust mite faeces and odours and gases such as tobacco smoke, organic compounds and odours.
The free extra filter is a combination of a true HEPA (fine particle filter) with a Granulated Activated Carbon Filter. The Granulated Activated Carbon Filter absorbs odours and tobacco smoke as well as harmful chemicals like formaldehyde and VOCs (volatile organic compounds).
The P340 comes with a pre-filter to remove large particle like pollen and large dust particles, a true HEPA filter to remove dust particle down to 0.3 of a micron and a granulated carbon filter to remove odours, smoke and harmful chemicals like VOCs and formaldehyde. A useful change filter indicator will let you know when it is time to replace the filters.
Useful features include the auto mode which will detect the most appropriate of the three performance levels depending on air quality. After turning on the unit for the first time it will run at the lowest fan level for a few minutes whilst it assesses the environment. The visual air quality indicator allows you to see at a glance the current level of airborne impurities, including dust, pollen, tobacco and gases. It is possible to manually control the fan level if that function is selected.
In addition, the timer function allows you to run the appliance for a set period before it turns off automatically.
The P340 also has an integrated ioniser to give the air a final polish for optimal clean air. This is controlled via the top panel and can be turned off.
Please ensure that you follow the advice in the manual, including how to replace the filter and cleaning the pre-filter.
