Polluted air is always a problem, caused by vapours from carpets, pollen count, germs or poor air quality after a long conference in the meeting room. All this can result in an inability to concentrate, headaches, a blocked nose and even asthma attacks. Say goodbye to these problems with our air purifier: switch on the air purifier – and breathe freely.

* Our AF 100 HEPA 13 comes with a European 2-pin plug. An adapter will be necessary for use in the UK.

How often is the filter changed?

In automatic mode, the air purifier automatically measures the air quality using a laser sensor and adapts its performance precisely. This ensures consistent air quality and optimal use of the filter. If a filter replacement is required, however, we have made sure that it's as easy as possible: open the side flap, replace the cartridge filter, done!

As a general rule of thumb, the more often a machine is used, the more frequently the in-built filter should be replaced or cleaned in order to ensure reliable efficiency. A tangible decrease in suction power in the air filter is an indication that the filter needs to be changed. Ideally, the HEPA 14 filter should be replaced every three months. In hygiene-sensitive areas, it is recommended to change the filter every month.

Clean or replace the filter?

Consistently high filter strength and regular filter replacement are particularly important for allergy sufferers. A filter gradually loses its effectiveness depending on how it is used and the strain it is placed under – it is then time for it to be replaced. Regular change intervals are the only way to ensure consistently high quality and hygienic cleanliness. Cleaning the HEPA 14 filter with water is not recommended.
