With the AEG GR201SMCC S-BAG (12 units), you'll get a new motor filter and fragrance granules in addition to a supply of vacuum cleaner bags. If you replace the vacuum cleaner bag every 3 months, this package will have enough bags for 3 years. Apart from that, it's necessary to replace the motor filter every year. This filter protects the motor against dust particles flying around in the vacuum. Which is nice, because that way the vacuum stays dust-free and will last longer. Want the vacuum's exhaust air to leave a pleasant aroma in your living room? Just vacuum up the included fragrance granules. That way, not only will the floor be dust-free, but the whole house will smell nice and fresh. The vacuum cleaner bags are suitable for all S-bag AEG and Philips bagged vacuums.
