Products Description
Our 1 micron filter bag is designed to capture submicron particles in liquids and air streams. Made from polyester felt, polypropylene felt or FDA-compliant materials, it provides ultra-fine deep filtration to remove particles as small as 1 micron with minimal pressure drop.
Backed by proven case study performance, such as extending bag life by 20% and energy savings in cement and steel mills, the bag is ideal for any application requiring high purity, low maintenance and customizable configurations.
Product Highlights
Sub-micron efficiency
Reliably removes 99.9% of particles ≥1 μm, including sludge, bacteria, and fine contaminants, ensuring high purity output.
Welded or Stitched Construction
Eliminates pinhole bypass (welding) or provides cost-effective stitched seams.
Glazed Finish
Minimizes fiber migration and ensures filtrate cleanliness.
Ring/Flange Materials
Choose from 304 stainless steel, polypropylene and more for chemical compatibility and secure sealing.

Process Technology
Seam Integrity
Ultrasonic welding technology eliminates glue contamination risks.
Precision Layering
3D melt-blown media with gradient density for depth filtration and high dirt-holding capacity.
Rigorous Testing
Each batch undergoes bubble point, tensile strength, and particulate shedding tests (ISO 9001-certified facility).
Applications
1 Micron Filter Bags are used where ultra-fine particulates must be removed:
- Water treatment & RO prefiltration (protects membranes)
- Food & beverage (juice, beer, dairy-FDA‐compliant media)
- Chemical processing (solvents, resins)
- Pharmaceuticals & biotech (aseptic filtration)
- Paints, inks & coatings (removes gel particles)
- Oil & gas (hydraulic fluids, coolants)
Are these bags compatible with high-temperature oils?
Yes. Our PES (polyethersulfone) and PTFE-coated bags withstand temperatures up to 135°C. Share your fluid specs, and we'll recommend the optimal material.
Can I retrofit your bags into my existing housing?
95% of standard housings (e.g., Pentair, Eaton, Parker) are compatible. Send us your housing model or dimensions, and we'll confirm fitment or propose custom sizing.
How often should 1-micron filter bags be replaced?
Replacement intervals depend on contaminant load and operating pressure. Most clients report 2–8 weeks in continuous use. Monitor pressure gauges – a 10–15 psi increase typically signals saturation.
