Because you care about clean air, rely on the proven and patented technology of Ultra-Web® nanofiber cartridge filters. Now standard in all Donaldson® Torit® dust collectors and available as replacement for any cartridge collector, Ultra-Web is the only cartridge filter engineered to deliver cleaner air, longer filter life and lower costs.

Exclusive Ultra-Web provides cleaner air with a MERV 13 efficiency rating, surface-loading nanofiber technology that captures even submicron particles and lower emissions of 40% or more. And Ultra-Web is better for your bottom line because it lasts up to 2x longer than commodity filters, adding up to significant savings in energy, filter and labor costs.

Make your air cleaner with better Ultra-Web filters.

The Ultra-Web advantage is cleaner air. Nanofibers are scientifically proven to have an advantage in efficiency and pressure drop. Ultra-Web nanofibers are patented and made with an electrospinning process that produces a very fine, continuous fiber of 0.2-0.3 micron in diameter to form a permanent web-like net with very fine interfiber spaces. This nanofiber "web" is constructed on a variety of media, resulting in:

• Advanced media that captures submicron and larger dust particles
• A media that traps dust on the surface and promotes self-cleaning
• Better pulse cleaning and lower stabilized pressure drop
• Cleaner air, longer filter life, and greater cost savings
