Ultra-Web Filters


Ultra-Web filters are offered for a full range of dust, fume and mist collection applications, Donaldson Ultra-Web® filters outperform and outlast other filters.

Ultra-Web is proprietary and made with an electrospinning process that produces a very fine, continuous, resilient fibre of 0.2-0.3 micron in diameter to form a permanent web-like net. This fine fiber “web” with its very fine interfiber spaces is constructed onto tough cellulose substrate media, resulting in:

  • A more robust media that captures even submicron dust on the surface
  • Better pulse cleaning and lower pressure drop
  • Cleaner air, longer filter life, and greater cost savings


  • Fine fibre technology ensures longer filter life at a significantly lower pressure drop
  • Substrate media features increased rigidity, higher durability, and superior cleanability
  • MERV 15* filtration efficiency rating per ASHRAE 52.2-2012
  • Superior particle release due to surface filtration
    Lower pressure drop saves energy
  • Longer filter life reduces replacement and maintenance costs
  • Lightweight and easy to install
  • Flame retardant media available
  • Stainless steel construction available
