The durable synthetic material ensures optimal airflow and high suction power throughout the entire usage period as the vacuum bag fills up. It filters up to 99% of all particles – even the smallest particles measuring 1 micrometer (15 times smaller than the diameter of a hair). The air is filtered 40% more efficiently than with paper bags; particles such as allergens and certain bacteria are reliably removed from the air. This vacuum bag, featuring a special fold and unique patented cardboard, is easy to install in the vacuum cleaner and is hygienic, as the bag automatically seals upon removal, allowing for quick and clean disposal without spilling the trapped dirt. The package contains 12 bags. Compatible with over 70 models from the brands AEG, Electrolux, and Philips.
