Boshart 14-GSP1 10" Spun Poly Depth Cartridge Filter

The Boshart 14-GSP1 Series is a 10" giant spun polypropylene depth cartridge filter available in micron ratings from 5 micron to 25 micron, built using melt blown technology into a multi-layer structure for superior filter efficiency, reduced pressure drop, and increased cartridge life. It is sized to fit most standard filter housings on the market and is intended for rough-in water filtration applications where a plumber or contractor needs a reliable, high-capacity sediment cartridge behind the wall or under the sink. The gradient four-layer (outside-in) construction with varied micron rate targets particles effectively while extending service life to up to two times that of comparable double-layer cartridges, regardless of which micron rating is selected.

Key Features

  • Trade Size: 10" giant spun cartridge sized to fit most standard filter housings on the market.
  • Filtration Rating Range: Available from 5 micron up to 25 micron, letting installers match the cartridge to the sediment reduction level required for the application.
  • Durable Construction: 100% high purity polypropylene that is surfactant free, binder free, and adhesive free for good chemical resistance and resistance to bacterial attack.
  • Gradient Four-Layer Design: Outside-in, varied micron rate filter structure captures particles effectively and prolongs cartridge life versus standard double-layer cartridges.
  • Extended Service Life: Melt blown multi-layer structure reduces pressure drop and can achieve up to two times the cartridge life of double-layer designs.
  • Flow Rate Flexibility: Rated flow rates reflect maximum filtration efficiency; the cartridge can be used above listed flow rates, though filtration effectiveness is reduced.

Technical Specifications

  • Country of Origin: TWN
  • Prop 65 Warning: No
  • Packaging: 8 ea per case

Typical Applications

  • Residential and Commercial Rough-In Water Filtration Systems
  • Sediment Reduction in Point-of-Entry Filter Housings
  • Well Water and Municipal Water Pre-Filtration
  • Replacement Cartridge for Standard 10" Filter Housings
  • New Construction and Filter System Retrofits

Why Boshart?

Boshart's 14-GSP1 Series spun poly depth cartridges are manufactured from 100% high purity polypropylene using melt blown technology to deliver consistent filtration performance and extended service life across the full 5 micron to 25 micron lineup. The gradient four-layer construction is engineered to reduce pressure drop while maintaining effective particle capture across the rated micron range, giving contractors and plumbers a dependable sediment cartridge for rough-in water filtration installations. Whether a job calls for tighter 5 micron filtration or the higher-capacity 25 micron rating, the 14-GSP1 Series delivers the same durable, high-purity polypropylene build and consistent housing fit that professionals rely on for repeat installations and replacements.

Boshart 14-GSP1-25 – Frequently Asked Questions

1) Should I order the 5 micron or the 25 micron version of the 14-GSP1?
Two ratings are offered: 14-GSP1-05 at 5 micron and 14-GSP1-25 at 25 micron. Go 25 micron when you are knocking down coarse sand and grit on well water, or as a pre-filter ahead of a finer stage, because the open media holds more dirt before pressure drop shows up. Go 5 micron where you need finer sediment reduction, for example ahead of a carbon or RO stage or on municipal water carrying fine silt. Both ratings use the same 100 percent polypropylene four-layer build, so the only difference is the particle size captured.
2) Why does a gradient four-layer spun cartridge last longer than a regular sediment filter?
The 14-GSP1 is melt blown into four layers of varying micron rate, working outside-in, so coarse particles are trapped in the outer, more open layers and finer ones deeper in. That spreads the dirt load through the whole wall instead of plugging the surface, which lowers pressure drop and can give up to twice the service life of a comparable double-layer cartridge.
3) Can I run more flow through this filter than it is rated for?
Yes, the cartridge will pass more than its rated flow. The published flow rates are the point of maximum filtration efficiency, so above that the cartridge still flows but captures fewer particles at the stated micron rating. If a job needs both high flow and tight filtration, run parallel housings or step up the micron rating rather than overdriving a single 14-GSP1.
4) Is this spun poly cartridge safe on potable water and free of binders or surfactants?
The 14-GSP1 is built from 100 percent high purity polypropylene that is surfactant free, binder free and adhesive free, which is why it resists chemical attack and bacterial growth and does not leach wetting agents into the water. Boshart lists no Prop 65 warning on it.
5) Is the 14-GSP1 suitable for well water sediment, or do I need something else?
Well and municipal pre-filtration is exactly what this cartridge is for, along with sediment reduction in point-of-entry housings, rough-in filtration behind the wall or under the sink, and straight replacement in existing 10 inch housings. It is a mechanical sediment depth filter only, so it handles sand, silt and rust particles. It does not address taste, odor, chlorine or hardness, which need a carbon cartridge or a softener downstream.
6) How is the Boshart 14-GSP1 packed if I'm stocking replacements for a building?
Boshart packs the 14-GSP1 eight each per case, and a single cartridge weighs 0.880 pounds, so a full case is light enough to keep on the van or on a shelf in the maintenance room. Property managers running several filtered risers usually standardize on one micron rating across the building so any tech can swap a cartridge without checking which housing they're at.
7) What are the actual dimensions of the 14-GSP1 cartridge?
It is a nominal 10 inch cartridge, with Boshart listing 4.330 inches for both height and width figures on the spec record, which is the giant body diameter. If your housing currently holds a 2-1/2 inch diameter standard cartridge, this larger-diameter element is not the right replacement for it.
