The high grade of material, used for our genuine bags and filters, provides your vacuum cleaner with strong airflow and high suction power as well as a high filtration level and maximum dust retention.To ensure the performance of your cleaner, we recommend you to wash this filter each time it gets visibly soiled. Wash it with a brush under a tap and let the filter dry before putting it back. For optimum performance of your vacuum cleaner, your dustbag should be changed regularly and your filters should be changed every 5 dustbags. All filters should be replaced at least twice a year or when they become visibly soiled. Use of non original Electrolux dustbags and filters may adversely affect the performance of your vacuum cleaner.
