The replacement filter set for the RO-70S reverse osmosis system includes 4 cartridges K3. The set helps reduce pre-filtration costs and ensures that the K3 cartridge is replaced on time, protecting the system’s core—the RO-50S reverse osmosis membrane.

Pre-Filtration (K3)
The K3 replacement filter effectively pre-treats water by removing organic impurities, heavy metals, active chlorine, and iron while filtering particles 5 microns and larger. The increased amount of selective ion-exchange AQUALEN fibers provides high sediment-holding capacity and enhances the removal of colloidal and dissolved iron.

RO-70S system
The compact reverse osmosis system RO-70S covers all issues of home water purification and replaces bottled water as a much more budget-friendly option.

Powered by AQUAPHOR patented technologies, the RO-70S is significantly more compact and efficient than traditional RO units. The built-in 5 L water-on-water storage tank saves under-sink space and helps preserve up to 9 tons of water per year. The integrated in-tank mineralization system places the mineralizer directly inside the reservoir for effective and uniform enrichment of purified water. Even at low water pressure from 0.2 MPa / 2 bar, the system ensures a stable, smooth flow of purified water. The mineralizer is placed directly inside the reservoir, ensuring more effective water mineralization.

AQUAPHOR filtration systems effectively reduce PFAS in water using high-quality activated carbon and advanced ion-exchange materials. These technologies help capture persistent contaminants, including PFOA and PFOS, delivering consistently cleaner drinking water for everyday use.
