DAMN Filters offers three solid media types for general dry dust. Specialty media available on request.

General Dry Dust Media

High Temperature Media

  • High Temp – for over 275°F
  • Moderate-Temp Conductive
  • Spunbond w/ PTFE – for under 275°F
  • Specialty high-temp media? Just ask

Static or Moisture Sensitive Media

  • Spunbond Polyester with PTFE
  • Carbon Impregnated Cellulose Blend
  • Moderate-Temp Spunbond
  • Other exotic media? Let us take a look

🔥 FR media is standard on many filters and can be added to others on request. Just let us know what you need.

80% Cellulose / 20% Polyester Blend

80/20 is the industry standard for general-purpose dust collection. It's made from a blend of cellulose (paper) and polyester fibers, offering a good balance of performance, cost, and durability.

It’s not meant for moist or sticky dust and isn’t cleanable.

DAMN Filters - 80% / 20% - Cellulose/Polyester Paper Blend Specifications

Composition
Cellulose/Polyester paper blend
MERV Rating
MERV 10/11 
Max Temp
175°F (continuous)
Air Permeability:
15–25 CFM/ft² @ 0.5" W.C. (typical range)
ASHRAE Test
Initial 52.2
Applications
Grinding dust, woodworking, blast booths, powder & dry chemical processing, non-oily welding smoke
Notes
Non-washable. Flame resistant (FR) 80/20 available on request.

Think of 80/20 as the workhorse. Reliable, affordable, and good enough for most dry dust jobs where indoor air isn’t recirculated.

High Strength Nanofiber

Nanofiber filter media is not 100% nanofiber. Think of it as nano-wrapped 80/20. The thin layer of nanofiber improves surface loading, boosts filtration efficiency for fine particles, and enhances pulse-cleaning performance.

DAMN Filters - Nanofiber Specifications

Composition
80/20 media with a nanofiber synthetic layer applied electrostatically
MERV rating
Merv 15
Max Temp
200°F. (maximum continuous temperature resistance)
Air Permeability:
25–26.5 CFM/ft² @ 0.5" W.C. (typical range)
Thickness
~.014"
Applications
Where fine particles are involved, like in welding, plasma cutting, powder coating, laser cutting, metalizing, and ferrous metal grinding.
Notes
Non-washable. Flame resistant (FR) nanofiber available on request.

Nanofiber filter media is ideal for systems that recirculate air back into the facility, where indoor air quality matters most. 

Its ultra-fine surface layer improves both particle capture efficiency and filter cleanability, while maintaining high airflow and offering resistance to many common industrial chemicals.

Customers typically report a 10% to 20% increase in filter life compared to standard media, thanks to reduced dust penetration and easier pulse-cleaning.

Best suited for high-particulate applications with fine or submicron dust, where surface-loading, dust release, and filtration efficiency are critical.

100% Spunbond Polyester

Spunbond polyester is a tough, synthetic media built for dry and mildly damp environments. Its smooth surface structure makes it highly washable; ideal for operations that need reusable filters or frequent cleaning between runs.

DAMN Filters - 100% Spunbond Polyester Specifications

Composition
100% Spunbonded Polyester
MERV rating
Merv 12
Max Temp
200°F (upgradable to 250°F)
Air Permeability:
25–30 CFM/ft² @ 0.5" W.C. (typical range)
Thickness
~0.024"
Mullen Burst
>300 psi
Applications
Chemical processing, pharmaceutical, pigment, plastics, mineral and metal processing, paper, cardboard, cement, cocoa, coffee, aluminized oxide, and rubber grinding dust.
Notes
Washable media. Flame resistant (FR) spunbond available on request.

Compared to cellulose blends, Spunbond resists abrasion, handles rougher dust, and stands up better to repeated maintenance. It tolerates light moisture and occasional humidity without breaking down.

Best for dry bulk materials, grain, plastic dust, and general industrial use—especially where cleanability, durability, and cost-per-cycle matter.
