Miele SF-HA 30 HEPA AirClean filter fits in S2000, S7000, C1, U1 and older S300-S899 series Miele vacuums.
This filter has a true HEPA filtration layer that removes 99.95%+ of microns 0.1 or greater in size.
Combined with a rubber air tight sealing system around the sides of the filter, you have the ideal setup for allergy sufferers or anyone looking to enjoy a higher quality of air in their home.
Miele has recommended changing once every 18 months for standard user volumes (or approx. 50hrs of use).
To help users remember when to change their filters, New upgraded SF-HA 30 featured with a time release color strip has been added. This strip slowly fills with red until after one years time, the whole strip becomes red.
