Description
SOFTENER DAFI FLOW COMFORT Under Sink Water Filter +2 Cartridges SET FOR 2 YEARS is a compact water filter installed under the sink, providing constant access to tasty, fresh, filtered water straight from the dedicated ALTO tap. The water filtration system reduces hardness, limits chlorine, improves taste and smell, and helps protect the kettle, coffee machine, and other kitchen appliances from limescale. It is a practical solution for everyday water treatment at home for people looking for a convenient alternative to bottled water and who do not need advanced systems such as reverse osmosis or an osmosis filter.

Tasty filtered water straight from the tap
Dafi Flow Comfort D1 is an under-sink system for filtering tap water, allowing you to use clean water immediately after opening the separate tap. The solution was designed with everyday convenience in mind: water is available quickly, without the limits typical of filter jugs and without the need to buy bottled water.
The system provides water suitable for drinking without boiling, as well as a base for preparing coffee, tea, and meals. At the same time, hardness reduction helps limit limescale buildup on kitchen appliances.

Extras
Spare D1 filter cartridge – the additional cartridge included in the set lets you prepare for continued system use right away.

ALTO tap and convenient dispensing of filtered water
The system includes a high-quality black ALTO tap. Filtered water is dispensed directly through it as soon as the tap is opened, so the water remains fresh and ready to use whenever you need it.
This way of operation distinguishes the system from solutions that require prior water storage. Dafi Flow Comfort is not a system such as an osmotic filter or reverse osmosis system, but for many users it is a more convenient choice where simplicity, compact size, and effective softening of utility water matter.

Detailed water filtration process
The filter media has been developed on the basis of high-quality ion-exchange resins and natural activated carbon. The cartridge design and individual layers are responsible for improving the water parameters and its practical usability.
- Filter cartridge head with four-stage adjustment, allowing the system operation to be matched to the water hardness in your home.
- Filter cartridge housing – durable and ensuring watertight water flow.
- Nonwoven fabric, which acts as a mechanical filter – it traps large solid particles, fine suspended matter, sand, and contaminants washed out from plumbing surfaces.
- Ion-exchange resin reduces water hardness responsible for limescale formation and lowers the content of metals such as copper and lead.
- Second layer of nonwoven fabric, through which the contaminant retention process is carried out again.
- Carbon block made from coconut shells – reduces chlorine and its compounds, thereby improving the taste and smell of the water. It also removes unwanted organic contaminants.
Softening adjustment and matching to water hardness
The filter head has 4-stage water softening adjustment. This allows the water filtration system to be adapted to the actual water hardness in your home installation.

The filtration level should be set after determining the hardness of the tap water using the test strip included in the set. Water hardness information can also be obtained from local water utilities.
Before first use, it is worth checking the water hardness and setting the appropriate hardness reduction level. Correct adjustment helps you make better use of the filter cartridge's capabilities and match the system operation to the conditions in a given home.

Safety and ease of use
Dafi Flow Comfort was designed so that everyday operation is simple and intuitive.
- Flood protection – the system shuts off water flow after the filter cartridge is removed.
- Easy access – air-bleeding and filter replacement lock buttons are located on the front of the unit.
- Compact dimensions – the filter fits easily in the cabinet under the sink.
- Non-invasive installation – installation is simple and can be done yourself.
Smart filter replacement indicator
The electronic LED indicator helps monitor system operation and reminds you when the cartridge needs attention. It is a practical solution that makes proper operation of the unit easier.

- LED indicating the type of filter cartridge,
- LED indicating the filter wear status,
- LED indicating the water hardness level,
- Sound indication of filter wear status,
- SIZE – button for setting the filter type,
- CHECK/RESET – button for resetting and checking the current filter wear status,
- HARD – button for setting water hardness reduction level A, B, C, D.
Everyday use
The system was created for easy and convenient operation. Cartridge replacement is simple, and the LED indicator supports wear control. The set includes two D1 cartridges, allowing you to plan long-term use right away.

One cartridge lifespan is up to 1 year, depending on water quality and the type of contaminants. This means that the set with two cartridges is a practical spare package for a long period of use.
To maintain high filtration quality, the filter cartridge should be replaced according to its wear and the system settings. The actual cartridge service life depends on water quality, hardness, and usage intensity.
