5 Filters You Need to Replace Your Resin Bonded Cartridge Filters

Many companies have stopped using resin bonded cartridge filters and have chosen cartridge filters from Gopani – known for their high filtration efficiency and relatively fair price. Gopani’s filter cartridges have a lower environmental impact, hence disposal issues are less, require lower maintenance, less frequent change-outs and all this lowers the cost of ownership.


Resin-bonded cartridge filters are known for their structural integrity and ability to filter viscous fluids.

They are typically used for the following applications:

  • Paints
  • Printing Inks
  • Adhesives
  • Resins
  • Polymers
  • Emulsions
  • Chemical coatings
  • Organic solvents
  • Petroleum products
  • Process water
  • Oilfield fluids
  • Animal oils
  • Waxes
  • Plasticisers

Many companies were until now using resin-bonded filters from brands like Parker, Cuno, and many more. However, environmentally conscious companies have stopped using resin-bonded filters.

Why are Companies looking for Resin Bonded Alternatives?

The fibers forming the resin bonded cartridge filter are bound by Phenolic resins such as Phenol and formaldehyde. A slurry of short fibers is bonded with resin, and there are high chances that the short fibers migrate out of the filter during service. Fibers in resin bonded cartridges are hard and when they release, and they may get embedded on gland packing and leave an impact on the filter sealing. Not only do these chemical compounds have serious implications on the environment, and create a lot of disposal issues for the user, they might pose serious hazards due to media migration.

Hazardous effects of Phenolic Resin

  • Eyes: The product can irritate and cause redness or burning sensation to the eyes.
  • Skin: If the product comes in contact with skin, it may lead to skin irritation and conditions like dermatitis.
  • Respiratory System: inhaling fumes from a heating product can cause irritation in the nose and mouth.
  • Ingestion: The product has low oral toxicity, however unlikely, ingestion must be avoided.
