Product Description

The PermaFilt Prefilter surrounds the 3-stage Carbon and HEPA filter, traps the smaller particles and significantly extends the life of the 3 stage filter. In order to properly maintain the effectiveness of the filters, all you have to do is periodically vacuum the outside of the machine, clearing away the larger and most visible dust.
