Mist Elimination and Filtration: The Role of Demister Pads

Alongside knitted mesh in the TechMesh product line, demister pads, also known as mist eliminators, are one of the most versatile and influential pieces of filtration equipment. Perhaps best known for their use in liquid-gas filtration, demister pads are vital to a variety of applications where mist elimination is required. In this blog, we will look at how demister pads filter liquids and gases so effectively, their end-use applications, the industries they serve, and more. 

What is a Demister Pad Used For?

As its name implies, mist eliminators remove moisture from gas streams. Vapor carries mist as it rises, and while gas is free to pass through knitted mesh unobstructed, individual mist droplets become trapped. Droplets grow in size as moisture accumulates, eventually causing the heaviest ones to fall back into the pool of liquid below. This coalescing process prevents even small drops of liquid from rising to the top of the tank.  

Liquid-Gas Filtration Capabilities

Demister Pad

The main function of demister pads in their various applications is separating liquid from gas streams. The mesh on these pads traps and manages potentially hazardous mist, while still allowing clean vapor to rise. From oil mist to sulfuric acid, CWI Tech-Mesh™ helps manage toxic material without inhibiting processing efficiency. 

Demister pads are available in a wide range of specialized alloys, densities and geometries. This allows their application in a multitude of industries. The corrosion resistance and durability of the materials used in demister pads allow for a long service life, and consistent performance without wearing down. 

They are lightweight, easy to install, and offer efficient filtration, making demister pads a star in the world of tech-mesh products. With no moving parts, low maintenance requirements and the ability to withstand harsh environments, demister pads serve each industry with consistent performance.  

Industries Served by Demister Pads


Many industries use demister pads in their day-to-day filtration and cleaning applications. These industries include: 

  • Oil and Gas 
  • Food and Beverage 
  • Air Pollution Control 
  • Mining 
  • Pharmaceuticals 
  • Water Treatment 

End-Use Applications of Demister Pads

Oil and Gas Plant

There are many end-use applications that demister pads are effective in. Their filtration capabilities are successful in applications such as: 

  • HVAC Systems 
  • Indoor Pools 
  • Natural Gas Processing 
  • Gas Scrubbing Systems 
  • Column Distillation 


Any application which involves purifying a gas with liquid-gas filtration can involve demister pads. Their consistent filtration produces products from clean and crisp alcoholic spirits, to clean air from pollution control devices.
