The T7500 features two oversized independently tested and certified HEPA filters, each rated at 99.99% efficiency at 0.3 microns. This model features a 20% increased filter area for improved performance. This model also features Teflon-coated sock-style pre-filters that provide 25 sq ft of surface area for nonstop grinding and long service life. In addition, the sealed cyclonic chamber separates and removes larger dust particles from the airstream before the air enters the pre-filter socks preventing premature filter loading.
