• Sealed tightly: the fit between the filter element and the machine directly affects the daily use effect. It is recommended to gently press along the edges to ensure that the edges are not raised. The finely worked filter element is equipped with high-elastic sealing cotton around it. After installation, it fits tightly with the filter tank.
• Save your mind when installing: when you replace the filter element yourself, whether disassembly is smooth affects the experience. It is recommended to turn off the power before operation, gently pull out the old filter element, and observe the direction of the card slot to install the new filter element. Reasonably designed filter element adopts a symmetrical structure or a clear indication of the installation direction, when pushed smoothly without cartons, there will be a slight clicking feeling after installation, no need to repeatedly adjust the position.
• Material stability: After long-term use of the filter element, the stability of the material depends on the use experience. It is recommended to place the air purifier away from the humidifier or kitchen oil smoke to avoid moisture or adsorption of the filter element. It is not easy to clot, collapse or loose detachment in normal indoor environments.
• Proper storage: If you purchase a spare filter cartridge in advance, the storage method will affect subsequent use. It is recommended to place the unsealed filter cartridge flat in a dry and cool cabinet to avoid heavy loads. The outer layer of the filter cartridge is tightly packed with a plastic seal film and a cardboard box, even if it is stored for more than six months, the filter paper will still remain flat and bracketed, without moisture deformation or odor absorption.
• Daily maintenance: Although the filter element can not be washed with water, but proper maintenance can prolong the use of the feeling. It is recommended to use the small brush head of the vacuum cleaner to gently suck the filter inlet air once every two weeks. When removing the cleaning is not easy to damage the internal filter material, simple maintenance can keep the inlet air smooth.
