Darlly 10-Inch Big Blue Meltblown Sediment Filter Cartridge – 5 Micron

The Darlly-branded 10-inch Big Blue 5 micron meltblown polypropylene cartridge is a depth sediment filter for standard 10-inch Big Blue housings. It reduces suspended particles such as sand, silt, rust flakes and other visible debris, helping to protect downstream filtration and water-treatment equipment.

This 5 micron model is best suited to: general domestic sediment filtration, offering a practical balance between fine-particle reduction, flow and cartridge life.

Key Features

• Meltblown polypropylene depth-filtration media
• Reduces suspended sediment without adding taste or odour to the water
• Helps protect carbon filters, softeners, reverse-osmosis systems, pumps and UV systems from particulate loading
• Disposable cartridge design for straightforward maintenance
• Quantity: 1 cartridge

Darlly Construction

• Polypropylene fibres are thermally fused without chemical glues
• Graded-density depth structure traps particles through the cartridge rather than only on the surface
• Designed for good dirt-holding capacity with a low initial pressure drop
• Suitable for sediment prefiltration in domestic, commercial and process-water applications

Specifications

• SKU: H2OW76
• Range: Darlly
• Cartridge format: Big Blue
• Nominal size: 10-inch (approximately 248–254 mm, depending on the housing standard)
• Approximate outside diameter: 115 mm
• Micron rating: 5 micron
• Filter media: Meltblown polypropylene
• Compatible housing: standard 10-inch Big Blue

Understanding Micron Ratings

• A smaller micron number provides finer particle filtration but may block sooner where sediment levels are high
• 0.5–1 micron: fine sediment polishing, normally after coarser prefiltration
• 5 micron: a popular general-purpose choice for domestic sediment filtration
• 10–20 micron: medium prefiltration that balances particle removal and flow
• 50–100 micron: coarse prefiltration for larger suspended particles and heavier sediment loads
• Micron rating describes particle filtration; it does not indicate removal of dissolved substances

Common Uses

• Domestic point-of-use and whole-house sediment filtration
• Borehole, wellpoint and rainwater prefiltration where suspended sediment is present
• Prefiltration before carbon, softening, reverse osmosis or ultraviolet treatment
• Reducing visible sand, silt, rust flakes and particulate matter

Installation and Replacement

• Confirm the housing length and diameter before ordering; Slimline and Big Blue cartridges are not interchangeable
• Shut off the water supply and depressurise the housing before opening it
• Replace the cartridge when flow reduces, differential pressure rises or sediment begins to pass through
• Replacement frequency depends on water quality, water consumption and the sediment load

Important Information

• This cartridge filters suspended particles only
• It does not remove dissolved salts or TDS, and it does not disinfect microbiologically unsafe water
• Use appropriate additional treatment where chemical or microbiological contamination is present
