The customized shower PP filter cartridge replacement is designed to improve the quality of your shower water by removing visible impurities, rust, and sediments. Made from food-grade polypropylene (PP) material, it ensures safety, durability, and high performance in every drop.

This filter uses PP melt-blown technology, which provides stable filtration precision down to 5 microns. It effectively blocks particles, sand, and small rust from the water before it reaches your skin and hair.

Available in multiple standard sizes such as 24×80mm, 24×95mm, and 24×115mm, and also customizable to meet specific requirements, this PP filter cartridge is a reliable solution for both residential and commercial shower systems.

Material & Filtration Technology

The core material of this filter cartridge is food-grade polypropylene. It is a non-toxic, odorless thermoplastic polymer that meets safety standards for contact with drinking water.

The PP melt-blown process transforms raw polypropylene into fine fibers, creating a gradient structure with countless micropores. These micropores form a deep filtration layer that traps particles as small as 5 microns.

This technology offers excellent dirt-holding capacity, stable pressure resistance, and long service life. Compared with wound or pleated filters, melt-blown PP filters have a more uniform pore distribution, providing consistent water quality output.

Filtration Performance

The 5-micron filtration precision ensures efficient removal of visible contaminants such as:

Rust and metal particles from pipes
Sediment and sand
Suspended impurities and small particles

By eliminating these substances, the filter improves water clarity and prevents residue buildup on your skin and hair. It also helps extend the life of the showerhead by preventing clogging.

Because the PP material is free from additives or adhesives, there’s no risk of chemical leaching, making it ideal for use in bathrooms where water comes into direct contact with the body.

Sizes & Custom Options

Common sizes include: 26x60mm, 24×80mm, 24×95mm, 24×115mm

We also offer customized dimensions to fit different shower filter housings or systems. The cartridge can be produced according to specific diameter, length, or interface requirements.

OEM/ODM customization includes:

Private label printing
Different PP densities for varying filtration precision (1–20 microns)
Color customization (white, gray, black, ect.)
Packaging design and logo printing

This flexibility allows distributors, brand owners, and equipment manufacturers to create personalized filtration products that match their target markets.

Applications

The Customized Shower PP Filter Cartridge is suitable for a wide range of applications, including:

Household shower filters — for purer, safer bath water.
Hotel and spa facilities — to ensure consistent water quality for guests.
Bathroom filter systems — as a first-stage filter for removing large impurities.
Pre-filtration in combined filter units — paired with carbon filters or ACF filters for multi-stage purification.

It can also serve as a replacement cartridge for various brands of shower filters, providing easy installation and stable compatibility.

How It Works

Water enters from one side of the filter cartridge and passes through the gradient PP melt-blown layer.

The outer layer captures larger particles such as sand and rust.
The inner layer traps finer impurities down to 5 microns.

This multi-layer depth filtration structure increases dirt-holding capacity and extends cartridge lifespan. As a result, the shower water becomes cleaner, softer, and safer for daily use.

When the flow rate decreases significantly or visible dirt appears on the surface, it’s time to replace the cartridge. Typically, replacement is recommended every 2–3 months, depending on water quality and usage frequency.
