Miele Active AirClean Filter with TimeStrip

This product is excellent as is the cleaner - very robust

When new one is fitted can clearly see and feel a difference in performance.

The filter is easy to fit but there are no instructions or indeed any warning that the time strip designed to let you know when the filter needs replacement contains a red oil based dye. Inadvertently I pressed the arrow on the filter as I fitted it...

We find it worthwhile to fit such a filter regularly.
