The Miele SF-AA50 Active AirClean Filter replaces the old AAC50 Active Filter.Miele activated carbon for odor control with AirClean particle filter. Fits Miele Compact C2 and Complete C3 canister vacuums, as well as S4000, S5000, S6000, & S8000 Series Modles. Now with Timestrip technology, the filter will let you know when it needs to be changed. How The Miele Active Filter Works: The SF-AA50 is filled with carbon which helps absorb gas and odors before exhausting from the vacuum. The carbon is sandwiched between two Super AirClean filters that will filter out any small particles not trapped by the bag. The Miele Active Filter Is Best For: With a good amount of carbon the Active Filter works best for ridding your home of odors during and after vacuuming. Pets are normally the culprit, finer hairs and dander that are not trapped by the bag will burn off in the motor. The carbon helps trap the odor those oils in the hair and dander are giving off. Carbon will also trap any other odor causing debris that is being sucked up by your Miele vacuum. The Miele Active Filter Is Not the Best For: Anybody suffering from severe asthma or allergies. The AA50 does NOT have HEPA filtration. When Does the Miele Active Filter need to be changed?The AA50 carbon vacuum filter can last up to a year of vacuuming. However if the carbon is absorbing odors at a faster rate the filter may need to be changed sooner. Rule of thumb is once odors start to be exhausted from the vacuum, the carbon is all used up and the filter needs to be changed.
