WPM20 USA is a sedimentation foam insert made of polypropylene nonwoven fabric for cold water filtration. It effectively captures fine solid contaminants such as sand, sludge, silt, and rust. Used in cartridge, osmotic, and under-sink filters, it helps protect subsequent filtration stages and the water installation.
WPM20 USA foam insert 20 microns is a sediment water cartridge designed for the pre-filtration of cold water in residential and commercial treatment systems. Made of polypropylene nonwoven fabric, it effectively traps fine solid impurities such as sand, sludge, silt, and rust. It works well as a cartridge for a water filter, in under-sink installations, inline filters, and systems such as an osmosis filter, reverse osmosis filter, and a complete water filtration system. It helps protect subsequent treatment stages, including specialist cartridges and the osmotic membrane, as well as the water installation itself.

The WPM20 USA model was designed to remove fine fractions of solid impurities from water. It is a practical solution wherever the goal is to limit the passage of mechanical particles into further installation components and filtration devices.
The 20-micron foam cartridge captures typical contaminants present in cold water, thereby supporting the proper operation of the entire water treatment system and reducing the load on subsequent filtration media.
The cartridge is made of polypropylene nonwoven fabric with a structure that enables water filtration throughout the entire volume of the material. This method of forming the nonwoven fabric supports effective capture of fine mechanical impurities as water flows through the cartridge.
In practice, this means effective pre-filtration, especially important in systems where the water then reaches more sensitive treatment components.
WPM20 USA is used in many popular water treatment and purification solutions. It can operate as a pre-filtration element wherever protection of the subsequent system stages is necessary.
It is a good choice both for simple mechanical installations and advanced setups such as a reverse osmosis system. In such applications, the cartridge helps limit the inflow of impurities to components requiring higher water purity.
One of the most important advantages of a sediment cartridge is its protective role. WPM20 USA helps protect not only the water installation, but also the other cartridges and components of the filtration system.
As a result, the cartridge can support more stable operation of the entire system and improve the operating conditions of subsequent filtration stages.
The product is intended for cold water filtration. This is important operating information, because maintaining the proper application range matters for filtration effectiveness and the correct performance of the cartridge in the system.
Important: the cartridge should only be used for cold water. Cartridge service life depends on water quality and the amount of trapped impurities, so the replacement frequency should be adjusted to the actual operating conditions of the installation.

It is a sediment cartridge intended for the mechanical filtration of cold water. Its task is to trap fine solid impurities such as sand, sludge, silt, and rust.
The cartridge removes fine fractions of mechanical impurities present in water, in particular sand, sludge, silt, and rust.
Yes, the cartridge can be used in systems such as a reverse osmosis filter and a reverse osmosis system. It serves as a pre-filtration stage there and helps protect the osmotic membrane against mechanical impurities.
The product is used, among others, in inline, osmosis, and under-sink filters. It can be part of a broader water filtration system.
This method of operation means that water is purified throughout the entire volume of the filtration material, not only on the surface. This supports the effective capture of fine mechanical impurities as water flows through the cartridge.
Yes, its use helps protect carbon, iron removal, and softening cartridges, as well as the osmotic membrane and the water installation itself, against excessive load from solid impurities.
WPM20 USA is intended for cold water filtration. It should not be used for hot water.
Cartridge service life depends on water quality and the amount of impurities trapped during operation. The more mechanical sediment is present in the water, the sooner the cartridge may require replacement.
