800 Series 800 Series Air Purifier AC0820/10

The filter should be changed approximately every 6 to 7 months to ensure optimum performance. It is recommended to replace all three filters (HEPA, activated carbon and pre-filter) at the same time to achieve the best air quality.

The filter goes for all air filters of the 800 series. The ACXXXX number is usually just the colour of the unit. If you also want to filter odours, this one is really great. For fine dust etc., the cheaper one is also sufficient.
