Envirogen Fluxflo monofilament filter bags are a cost-effective solution for surface filtration (sieving). With a woven structure of single filaments, these filter bags deliver high-performance, solid, non-deformable particle removal at specific absolute micron ratings. This makes them ideal for many industrial applications, such as pre-filtration, final-filtration and polishing. And for a low total cost of ownership, our monofilament filter bags are washable and reusable, depending on the application.
Monofilament filter bags are ideal for many industries and applications, including:
- Bulk filtration
- Paint, coatings and resin filtration
- Water filtration
- Food and beverage filtration
- Chemical filtration
- Automotive manufacturing
- Metal washing
- Semiconductors and electronic fabrication
Our absolute rated filter bags are available in a range of sizes from 1 micron to 1200 microns and are available in a variety of materials, including:
- Nylon mesh monofilament
- Polypropylene mesh monofilament
- Polyester mesh monofilament
Our Fluxflo filter bags are manufactured using high-quality, 100% virgin fibres for consistent performance. For more demanding applications, we can supply filter bags in bespoke materials.
Sealing materials
We offer a range of sealing rings for our filter bags including:
- Galvanised steel
- Stainless steel 316
- Moulded polypropylene
- Moulded polyester
- Bespoke mouldings for compatibility with specialised filter bags

Our nylon monofilament filter bags are manufactured to ISO 9001 quality standards, under food safe and silicone-free conditions, to minimise contamination. In addition, our nylon monofilament filter media are compliant with the European Regulation (EC) No 1935/2004 and Commission Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food.
Fluxflo monofilament filter bags can be used with or without filter housing for complete versatility and lifting handles are provided as standard for easy installation and removal.
We take a solutions-based approach to monofilament filter bag selection, understanding your process filtration goals and giving expert advice on the bag filters, bag filter housings and consumables packages that best meet your needs. We also supply baskets, gaskets, magnetic inserts, bag retainers and liquid displacers as auxiliaries.
Tailored filtration solutions to meet your needs
Selecting the ideal monofilament filter bag material for your application will depend on the flow rate and viscosity of the liquid, the size and type of the particles to be removed, the required retention efficiency and the chemical and temperature compatibility of the media.
Our team of process experts recommend solutions to maximise the effectiveness of your filtration process, enabling you to hit production and quality targets with a low total cost of ownership
