DAFI 2-Stage Water Filter Flow Softener for the Whole House 1" + Cartridges

2-Stage flow filter for a home installation

The DAFI model is designed for direct installation in a home water system with a 1" connection. This solution is intended for operation at the inlet of the system, where the water is filtered before being distributed throughout the house.

The device design combines two important stages of water quality improvement: mechanical filtration and softening. This arrangement helps at the same time reduce solid contaminants and lower water hardness, which matters both for everyday user comfort and for the protection of fixtures and appliances.

The special housing design makes replacement of the cartridges inside easy and convenient. This is an important advantage wherever quick servicing without complicated steps is needed.

How 2-stage filtration works

Stage 1: mechanical filtration

The mechanical cartridge is responsible for retaining mechanical impurities present in the water. It effectively removes, among others:

• sand,
• rust,
• sediment.

The result is cleaner and clearer water for everyday use. Reducing the presence of mechanical impurities can also have a positive effect on the taste and smell of the water.

Stage 2: water softening

The softening cartridge removes calcium and magnesium ions from the water, which are responsible for its hardness. As a result, overall water hardness decreases, and so does the amount of deposits accumulating in the plumbing system, fixtures, and appliances.

Soft water helps reduce limescale problems, supports longer service life of household appliances, and can bring noticeable operating benefits, including lower detergent consumption and maintenance costs.

Key benefits in everyday use

Clean water

Mechanical filters effectively remove mechanical impurities from the water, such as sand, rust, and sediment, ensuring clean and clear water for everyday use.

Better taste and smell

Removing mechanical impurities improves the taste and smell of the water.

Easy cartridge replacement

The simple replacement process makes it easier to keep the filter in good condition and allows you to consistently maintain filtered water quality without unnecessary complications.

Removal of calcium and magnesium ions

The softening cartridge reduces ions responsible for water hardness, helping to reduce the amount of deposits.

Appliance protection

Soft water better protects household appliances against deposits, which can increase their durability and support efficient operation for longer.

Economic benefits

Reducing water hardness brings savings both in detergent use and in appliance maintenance costs.

Construction that supports system operation

Housing with air vent

The housing is equipped with an air vent that allows pressure inside the housing to be balanced with atmospheric pressure. This solution helps eliminate the risk of damage to filtration or sealing components.

The presence of the air vent supports more efficient operation of the filter and the in-line housing under different operating conditions and with varying pressure in the water system. This translates into improved system performance and longer service life of the equipment.

The role of seals in the system

Seals are included in the set and perform several important functions in the filtration system:

• they help maintain tightness between the components of the in-line housing and the filter cartridges,
• they prevent contaminants from entering the inside of the housing,
• they support maintaining proper pressure inside the housing, helping reduce air entering the system.

Good system sealing is important both for safe operation and for maintaining filtration efficiency.

Set contents

The set has been prepared to make installation and start-up of the water filtration system in a home installation easier. The set includes:

• DAFI 2-stage flow water filter,
• 3 mechanical cartridges,
• 3 water softening cartridges,
• seals,
• mounting wrench.

The mechanical cartridges are responsible for removing mechanical impurities, while the softening cartridges help reduce calcium and magnesium ions responsible for water hardness.

Operation and application

The filter is intended for direct installation in a home water system. It works well as a pre-treatment solution for whole-house water when the user wants to reduce mechanical impurities while also lowering water hardness.

This is a different type of solution than reverse osmosis, an osmotic filter, or a reverse osmosis filter, which is most often used at a single draw-off point. Here the system works in-line within the installation, supporting everyday treatment of utility water on a larger scale.

Regular replacement of the filter cartridges helps maintain high performance and user comfort. Thanks to the included mounting wrench and the service-friendly design, filter maintenance remains convenient also during later operation.

Cartridge service life depends on water quality and the type of contaminants.
