Festool HF-Sys-Air-M Main Filter for Sys-Air M Air Purifier

The Festool HF-SYS-AIR-M is a replacement main filter designed specifically for the Festool SYS-AIR M air purifier, delivering class M filtration for hazardous airborne dust including wood dust and mineral dust. At the heart of this filter is Festool's TripleV design — a specially developed filter shape with a significantly larger surface area than conventional filters. This increased surface area allows the filter to capture more dust particles before clogging, resulting in longer intervals between replacements and a longer overall service life. With a filtration efficiency of more than 99.9% for dust class M, this filter supports compliance with health and safety requirements on site, including COSHH-regulated airborne dust. It is designed to be replaced without tools, making maintenance quick and straightforward — an important consideration when working in dusty environments where downtime needs to be minimised.
