Flex PES Class M Flat Folded Filter

The Flex Vacuum has three filters, two of which may need to be changed over time. This one is the main filter that goes in the front of the vacuum. This filter is made of fleece that is coated with Teflon. This creates a surface that is dirt repellent and prevents crap from clogging the filter over time. This means that the filter is easier to clean and will last longer than a filter that doesn’t have this feature. This filter is “Class M.” That means that it is rated for use in extracting and removing harmful fine dust.
