This article describes the Dyson Slim DC18 Filter Cleaning process for the Pre-filter and the HEPA (Highly Efficient Particle Arrester) Post-filter.
Many devices in this world which pump air have air filters. They’re installed to stop dirt harming mechanisms, bearings, etc.. Without filters that dirt would ultimately make them perform badly or fail. The air filters clog up instead and have to be replaced or cleaned at regular intervals. The Dyson Slim DC18 is no different. It has two air filters, one to protect the motor and the other (the HEPA filter) to protect the local environment and the people in it.
