 Pre-filter: The pre-filter is usually located in front of the other filters to catch large particles such as dust and fine debris. It can reduce the load of other filters and prolong their service life.

 These smart vacuum cleaner filter accessories can be selected and replaced according to their respective characteristics to ensure the normal operation of the vacuum cleaner and the effect of cleaning the air. Depending on the model and brand of vacuum cleaner, there may be different types and specifications of filter accessories to choose from and purchase.
