With this filter bag set, the pond vacuum cleaner also cuts a fine figure when it comes to dry vacuuming. Once the filter bag is full, the suction power drops quickly. Regular change of the paper filter bag keeps the performance of your vacuum at the usual high level even after many dry suction processes. These three replacement filter bags are classified as HEPA and safely hold up to 95% of all particle sizes inside. This keeps the burden of allergens and fine dusts at a pleasant low level even in the workshop or garage.
