Philips E200S vacuum cleaner bag. The s-bag Classic is a high-quality paper dust bag that removes more than 95% of dust and other particles, making it significantly more efficient than conventional paper dust bags. Improved sealing system – durable and hygienic: the redesigned sealing system is much stronger thanks to the more durable material and new technology. This ensures that the s-bag® always seals perfectly, does not tear and does not leak. The dust bag is easy to insert into the vacuum cleaner and is also hygienic because it closes automatically when removed. Replacing the dust bag is quick and clean. For optimum performance, dust bags should be replaced regularly, while the filters should be replaced after every fifth dust bag change. Filters should be replaced at least every six months or whenever they are visibly dirty. Using non-original s-bag® filters may significantly reduce the performance of the vacuum cleaner.
