Why should I upgrade my single-stage filter?
Standard single-stage dust collectors are typically equipped with a cloth bag filter rated for particles 1 micron in size. While effective for trapping some dusts, they still let through the smallest particles that are in fact the most damaging to your health as they can become deeply lodged within your sinus cavities. Additionally, many wood dust have been shown in studies to be carcinogenic.
This independently certified HEPA filter captures 99.97% of particles as small as 0.3 microns (the same level of filtration used in hospital environments) so woodworkers can rest assured that their hobby won't hurt their health.
