Boshart 14-SP1 Spun Poly Microfiber Depth Filter Cartridge, 10"

Boshart 14-SP1 Spun Poly Microfiber Depth Filter Cartridge, 10"

The Boshart 14-SP1 Series is a 10" standard spun polypropylene depth filter cartridge built for whole-house and point-of-entry water filtration housings used in plumbing rough-in and water treatment installations. The 14-SP1 platform is available in 5 micron and 25 micron rated versions, letting contractors match particulate capture to the application while keeping the same drop-in 10" footprint across the line. Manufactured with melt blown technology into a multi-layer structure, this cartridge is designed to deliver superior filter efficiency, reduced pressure drop, and extended service life compared to standard single-layer filters. The gradient four-layer, outside-in construction with a varied micron rate filter structure captures particles effectively across the depth of the cartridge rather than only at the surface, which is why Boshart states this design can achieve service life up to two times that of double-layer cartridges. Sized to fit most standard 10" housings on the market, the 14-SP1 Series is a practical drop-in replacement for plumbers and water treatment contractors servicing residential and light commercial systems.

Key Features

• Trade Size: 10" standard length, sized to meet most housings in the market for straightforward drop-in installation.
• Filtration Rating: Available in 5 micron and 25 micron ratings for effective particulate capture across a range of applications; listed flow rates are based on maximum filtering efficiency, and the cartridge can be run above this flow but with reduced filtering performance.
• Durable Construction: 100% high purity polypropylene material that is surfactant free, binder free, and adhesive free, offering good chemical resistance and resistance to bacterial attack.
• Gradient Four-Layer Design: Outside-in, varied micron rate filter structure that captures particles progressively through the depth of the cartridge to prolong service life versus double-layer designs.
• Melt Blown Technology: Spun into a multi-layer structure for superior filter efficiency and reduced pressure drop across the cartridge.
• Extended Cartridge Life: Structure engineered to achieve up to two times the service life of comparable double-layer spun cartridges.
