Filter Media
The Foundation of Superior Filtration
Plating filter media are critical for removing solid particles, oils, and organic impurities from metal finishing baths. By matching the right media to your bath chemistry and micron rating, you can:
- Ensure smooth, bright deposits
- Reduce rejects
- Improve plating quality
- Extend bath life

Common Types of Filter Media
PSI provides a full range of filter media options to meet your specific process needs because clean solutions mean better results.
- Cartridges: String-wound, melt-blown, pleated, or carbon-impregnated (polypropylene or cotton) for general filtration or organic removal.
- Filter Bags: Polypropylene or nylon bags (felt or woven) with high dirt-holding capacity, available with various ring types.
- Filter Papers/Discs: Cellulose-based or polypropylene felt discs, sometimes precoated, for fine particulate removal.
- Carbon: Activated carbon (granular or cartridge) for removing organic impurities that cause haze or brittleness.
- Filter Aids: Diatomaceous earth or perlite used as a precoat on plate-and-frame filters for sub-micron filtration.
What do we need to know?
- Micron Rating: Determines particle size removed (e.g., 1 µm for high clarity, 5–15 µm for general nickel baths).
- Material Compatibility: Polypropylene for high chloride/fluoborate; cotton for sulfamate nickel.
- Bath Chemistry: Media selection depends on acid, alkaline, or specific metal baths (zinc, copper, nickel).
- Filtration Type: Depth filtration (polypropylene, polyester) for dirt-holding; surface filtration (paper, membrane) for fine filtration.
