Nylon Filter Bags- Applications and Benefits

Filter bags are commonly known as dust collectors and they are used in big industries to separate dust particles from gases or liquid. The efficiency level of these filter bags are really high and can hinder almost 99% of the dust particles. The reasons why they are so popular are because they are a cost effective technology. The filter bags are made-up of different materials such as cotton, synthetic or glass fiber.

Filter bags are categorized by the size of the pores which is in microns. They are available in micron range of 1 to 200 microns. Filter bags are of two types:

Monofilament Mesh Bags – They are made up single threaded material. It is an extremely tough material and efficient with precise weaving to ensure consistent pore sizes. It is reusable in many applications. Nylon filter bags are the most widely used filter bags. Rating of these filter bags exist between 1 to 1200 microns.

Multifilament Mesh Bags – They are made of multiple threads to increase strength and lower the cost. It is available in polyester and nylon. Multifilament Mesh Bags are available in micron ratings from 75 to 1500 microns.

Nylon filter bags are hydrophilic and no wetting agents are used in to manufacture. They ensure a test will be clean, pure, and produce more consistent results. They are extremely compatible with organic solvent, animal vegetables, petro oils and micro-organisms but poor compatibility with oxidizing agents and mineral acids.


· Filtration of raw water.

· Filtration of paint.

· Processing waste water.

· They are used as Pre-filter for RO membrane cartridge.

· High performance liquid chromatography (HPLC) sample preparations.

· Sterilize and clarify aqueous and organic solvent solution.


· Hydrophilic

· Superior strength

· Low extractable

· High surface area

· Exceptional sensitivity

· High protein binding capacity

· Lot-to-lot consistency

Nylon filter bags are extremely abrasion resistant, resistant to a broad range of chemicals, unaffected by metal fatigue or corrosion, and boasts high tensile strength. That is why why they are so popular in the industry.
