The main function of the battery filter is to allow the battery to dissipate heat quickly. It is a maintenance piece, as it is mostly installed under the rear seats, in order to prevent large particles of dust such as lint and hair generated by the internal circulation from coming into contact with the battery, and the main function is to keep the battery from getting hot, as it is dangerous. However, the filters are all internal with an electrostatic adsorption layer, so microscopic dust can be attracted to the filter as it passes through it, so it is recommended that the filters are changed frequently.
The Masuma battery filter has low resistance and high ventilation capacity, effectively intercepting dust, hair and other external matter, protecting the air in the battery pack equipment space from being clean and working properly.
