Description

4x DAFI Mechanical Polypropylene Filter 25 µm is a practical set of cartridges for 10-inch housings, intended for pre-filtration of water in the home. This filter cartridge helps trap sand, rust and other solid particles, thereby supporting the water filtration system, protecting the installation and safeguarding subsequent treatment stages such as a water filter, osmosis filter or reverse osmosis system. The set of 4 cartridges provides a convenient operating запас, a flow rate of up to 30 l/min and service life of one cartridge of up to 3 months, depending on water quality.

Effective mechanical filtration for everyday water treatment

The DAFI polypropylene cartridge has been designed as a mechanical filtration element whose task is to capture solid contaminants present in water. Filtration at the 25-micron level helps reduce the presence of sand, rust and other sediments that can worsen water use comfort and burden subsequent system components.

This solution works especially well as a pre-filter in domestic water treatment systems. It can support the operation of single inline housings, expanded multi-stage sets and installations where protection of subsequent filtration stages is important.

Key user benefits

  • Easy installation: the universal cartridge fits most 10-inch water filters, enabling quick and simple installation without the need for specialist tools.
  • High performance: with a flow rate of up to 30 liters/min, the filters provide a steady supply of purified water suitable for everyday use.
  • Long-lasting purification: each cartridge works for up to 3 months, depending on water quality and contamination level, which supports economical operation.
  • Versatility: the filters can be used individually or in multi-element configurations tailored to individual needs and water conditions.
  • Installation protection: mechanical sediment filtration helps reduce the load on pipes, fittings and subsequent filter cartridges.
  • Convenient запас: the set includes 4 cartridges, making it easier to plan regular replacement.

Where this cartridge works best

The DAFI mechanical cartridge set is a good choice wherever effective protection of the water system and subsequent filtration stages matters.

  • In old water supply systems, where mechanical contaminants are often present.
  • In places with water supply interruptions, ensuring continuous protection of the filtration system.
  • In homes requiring advanced water filtration, combining mechanical contaminant removal, water softening and nitrate elimination.

Thanks to the universal 10-inch format, the cartridge can operate both as a standalone water filter and as the first stage in more advanced treatment solutions, including those using reverse osmosis or a reverse osmosis filter.

Compatibility and installation

The cartridge fits DAFI filters and other 10-inch housings. The 10-inch installation size, i.e. approximately 25 cm, is one of the most commonly used standards in domestic filtration systems, which makes it easier to match the product to many popular housings.

The cartridge height is 24.8 cm. Before installation, it is worth checking compatibility with your housing and making sure the enclosure is designed for 10-inch cartridges.

One cartridge can operate for up to 3 months, however the actual service life depends on water quality and the amount of contaminants. In case of heavy dust or a high sediment level, replacement may be needed sooner. The recommended operating temperature is from 2 to 30°C.

System expansion possibilities

The polypropylene mechanical filter works very well as the first stage of filtration. In more advanced systems, it can work with other DAFI cartridges to create a more advanced water quality improvement setup.

Other original DAFI filters

With activated carbon

Effectively removes chlorine, its compounds and organic contaminants such as sand, fine suspensions, corrosion products, contaminants from plumbing systems and fats. As a result, the water taste improves and its discoloration and unpleasant odor disappear.

Softening

The filter equipped with ion-exchange resin softens water by reducing calcium and magnesium ions responsible for its hardness.

For nitrate removal

A specially developed filter with an anion resin effectively eliminates nitrates from drinking water, ensuring higher quality.

Questions

What is the DAFI 25 µm mechanical filter used for?

The cartridge is used for mechanical water filtration. It traps sand, rust and other solid particles of a size corresponding to the 25-micron grade, helping protect the water system and subsequent treatment stages.

Does this cartridge fit every water filter?

It fits DAFI filters and other housings in the 10-inch standard. Before purchase, it is worth checking whether the housing you use is designed for 10-inch cartridges and a height of about 24.8 cm.

How often should the cartridge be replaced?

One cartridge can be used for up to 3 months. The actual service period depends on water quality and the amount of mechanical contaminants, so with heavier contamination replacement may be necessary sooner.

What is the flow rate?

The flow rate is up to 30 liters per minute, which makes the cartridge convenient for use in domestic water filtration systems.

Is this cartridge suitable as the first stage for a reverse osmosis system?

Yes, the mechanical cartridge can be used as a pre-filter in installations such as an osmosis filter, reverse osmosis filter or a full reverse osmosis system. Its task is to protect subsequent filtration stages from mechanical sediment.

At what temperature can the filter operate?

The recommended operating temperature is from 2 to 30°C. Operation outside this range may reduce the effectiveness or durability of the cartridge.

What is included in the set?

The set includes 4 DAFI mechanical filter cartridges made of polypropylene, intended for 10-inch housings, with a filtration grade of 25 µm.

Does the cartridge also remove chlorine and improve water taste?

This model is a mechanical cartridge whose main task is to retain solid contaminants. If you also need chlorine reduction, improved taste, water softening or nitrate removal, it is worth expanding the system with appropriate specialized cartridges.

Where will such a filter work best?

This is a good solution for older water supply systems, places with water supply interruptions and homes using a more advanced water filtration and treatment system.
