Perfect if you have pets, the Miele SF AA-50 filter has a new minimal air flow active charcoal cassette which absorbs odours from the dustbag, keeping your pet smells at bay. This filter has been designed with an indicator ‘TimeStrip®' set to prompt you a year after it has been activated. Miele advise that you look to change your filter to ensure that your vacuum cleaner is working at its optimum performance. To activate the TimeStrip®, press on the green arrow to the left of the strip when the new filter is fitted. A red fluid starts to creep from left to right of the strip over a period of approximately one year. Once the fluid has reached the far end of the strip and the bar has changed completely to red, the word ‘Replace' will appear, indicating that a new filter should be fitted. Suitable for S4000, S5000 and S6000 series.
