[Hepa Filter] The HEPA filter is made of high-strength environmentally friendly materials, which can block most dust down to 0.3 microns. The filter can maintain the cleaning performance of the sweeper, while reducing the penetration of dust, pollen and other allergens into the air you breathe. Easy to assemble: The filter is located inside the dust container. Remove the dust container by grasping it firmly and pulling it out. To empty the dust container, locate the release latch and pull it open and empty it. Remove the old filter, then put the new filter back in the dustbin. Replacement filter: A dirty filter will significantly reduce suction power. Depending on the vacuuming frequency and the amount of dirt cleaned, for best performance, change the filter at least every 3 to 6 months. High-efficiency activated carbon filter absorbs household odors from pets, cooking, , forest fires and harmful substances Helps clean the vacuum cleaner and make your lifestyle healthier Applicable
