Kuna Filter – An expert approach to clean water

When a company with over 30 years of industry experience designs water filters, you can be sure of one thing: they're built to last. The Kuna Filter brand responds to the needs of customers seeking premium equipment at a reasonable price. Their reverse osmosis (RO) systems combine carefully selected, health-safe components, exceptional filtration accuracy, and advanced water enrichment systems (mineralization and ionization). This is water that not only quenches your thirst but also genuinely benefits your health.

Why does Kuna Filter stand out on the market?

The market is full of cheap, no-name filters whose plastics can release harmful substances (such as BPA) into the water. The Kuna Filter goes in a completely different direction:
✔ Certified components: Hoses, connectors and housings come from renowned global suppliers.
✔ Safety (BPA Free): Guarantee that materials in contact with water are absolutely safe and neutral.
✔ Dual spouts: Many Kuna Filter systems offer dual-circuit taps, so you can draw separate water for cooking (pure H2O) and drinking (mineralized water).

Ionized and alkaline water (Red-Ox)

What attracts customers to the Kuna Filter brand is their approach to the final stage of treatment. In addition to the traditional dolomite cartridge (which adds calcium and magnesium), higher-end models feature water ionizers .
These contributions:
1. Raises the pH of water: Creating alkaline water that helps deacidify the body.
2. Lowers the ORP (Red-Ox) potential: Water gains antioxidant properties, helping to fight free radicals, which slows down the aging process.

Kuna Filter filters feature a compact design, the highest quality tubing and crystal clear water with minerals.

Series tailored to you

Kuna Filter offers both classic built-in systems (e.g., the Comfort and Prestige series), which enhance the aesthetics of your cabinet and simplify cartridge replacement, and traditional open systems. All have one thing in common: powerful removal of limescale, chlorine, heavy metals, microplastics, and bacteria.

Frequently asked questions

  • Kuna Filter is a private label created by the companyKuna System– one of the oldest and most experienced distributors of water treatment systems in Poland. With decades of experience servicing equipment from around the world, the company has created its own line of filters, eliminating the most common drawbacks of cheap designs.


  • Yes, very much so! The heart of the device is an osmotic membrane that removes 99% of contaminants (including microplastics, viruses, and rust). The water then passes throughmineralizing insert(and in some models also ionizing), which saturates it with minerals. You drink water with the parameters of pure spring water.


  • This is a specialized post-filter used in advanced Kuna Filter models. It contains bioceramic and magnesium deposits. It changes the water's pH tobasic (alkaline)and lowers its oxidation potential. Such water is better absorbed by cells, provides excellent hydration, and helps neutralize body acidity.

  • To maintain the highest water quality, the initial cartridges (sediment and carbon) should be replaced every6 months. The final cartridges (mineralizer, ionizer) are usually replaced every12 monthsThe osmotic membrane itself (thanks to the protection provided by pre-filters) lasts from up to 5 years.


  • It depends on the model chosen, but modern cassette systems (built-in type) are very ergonomically designed. The entire system, including the storage tank, typically takes up about half of a standard 60 cm wide under-sink cabinet.
