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.

Technical Specifications

  • Country of Origin: Taiwan
  • Prop 65 Warning: No
  • Packaging: 20 ea per case
  • Micron Rating: 5 micron or 25 micron, per model selected
  • Length: 10" standard
  • Material: 100% high purity polypropylene

Typical Applications

  • Whole-House Water Filtration Systems
  • Residential and Light Commercial Point-of-Entry Filtration
  • Standard 10" Filter Housing Replacement Cartridge
  • Sediment and Particulate Pre-Filtration Ahead of Downstream Treatment Equipment
  • Rough-In Water Treatment Installations Requiring Standard-Fit Cartridges

Why Boshart?

Boshart's 14-SP1 spun filter cartridges are built from 100% high purity polypropylene with a gradient four-layer, melt blown structure engineered specifically to reduce pressure drop and extend cartridge life over standard double-layer designs. The surfactant free, binder free, and adhesive free construction gives contractors and plumbers a chemically resistant cartridge that resists bacterial attack, sized to drop into most standard 10" housings already in the field. Available in 5 micron and 25 micron ratings, the 14-SP1 Series lets crews standardize on a dependable, long-life sediment cartridge for water filtration rough-in work while matching filtration performance to each job's requirements, delivering consistent, code-ready performance case after case.

Boshart 14-SP1-05 – Frequently Asked Questions

1) Will the Boshart 14-SP1 fit a standard 10-inch whole-house filter housing?
Yes. The 14-SP1 is a 10 inch standard-length cartridge measuring 2.480 inches across, which is the common drop-in size for standard 10 inch whole-house and point-of-entry housings. Boshart sizes it to meet most housings in the market, so it goes into an existing sump without adapters.
2) Should I use the 5 micron or the 25 micron version of the 14-SP1?
Both share the same 10 inch body, so pick on water quality. The 25 micron catches coarser sand and grit and loads up slower, which suits well water or a first-stage pre-filter ahead of other treatment equipment. The 5 micron takes out finer silt and is the better choice as a polishing stage or ahead of carbon or UV. Order code 14-SP1-05 for 5 micron, 14-SP1-25 for 25 micron.
3) How does a four-layer spun cartridge differ from a standard single or double layer sediment filter?
The 14-SP1 is melt blown into a gradient four-layer structure with a varied micron rate from the outside in, so coarse particles are caught at the outer layers and finer ones deeper in the wall. That spreads the loading through the depth instead of plugging the surface, which is why Boshart states it can reach up to twice the service life of a double-layer spun cartridge, with lower pressure drop across it.
4) Is this filter cartridge safe to use ahead of a carbon or RO stage, or will it add anything to the water?
The media is 100% high purity polypropylene, surfactant free, binder free and adhesive free, so there are no wetting agents or glues to leach into the stream. It also carries no Prop 65 warning. That construction is why it is commonly run as the sediment pre-filter ahead of downstream treatment equipment.
5) Can I run more flow through the 14-SP1 than its rated flow?
You can, but you give up filtration performance. Boshart's listed flow rates are based on maximum filtering efficiency; run above that and the cartridge still passes water but captures less. If the system demand is higher than one 10 inch cartridge handles cleanly, use a larger housing or parallel cartridges rather than overdriving a single one.
6) How does the 14-SP1 hold up in well water that has bacteria or chemical content?
Polypropylene gives the cartridge good chemical resistance and resistance to bacterial attack, which is one reason it is used for residential and light commercial point-of-entry work. It is a sediment and particulate depth filter, not a disinfection device, so bacteria control still needs UV or chlorination downstream.
7) How are Boshart 14-SP1 cartridges packaged for a property manager stocking multiple buildings?
They ship 20 each per case. At 0.220 pounds per cartridge they are light to stage, and since both the 5 and 25 micron versions use the same 10 inch footprint you can stock one size of housing across a portfolio and change only the micron rating by property.
8) Is the Boshart 14-SP1 a pleated or a depth filter, and does that change how often I swap it?
It is a depth filter, spun rather than pleated. A pleated cartridge holds dirt on a large surface area and some types can be rinsed; the 14-SP1 traps particles progressively through the wall thickness, so it is a throwaway cartridge, but the four-layer gradient is what lets it run longer between changes than a basic spun filter before pressure drop climbs.
