The replacement filter set for the RO-70S EU reverse osmosis system includes 4 cartridges K1. The set helps reduce pre-filtration costs and ensures that the K1 cartridge is replaced on time, protecting the system’s core—the RO-100S reverse osmosis membrane.

2-in-1 Pre-Filter (K1)

The K1 2-in-1 cartridge combines two active filtration zones for advanced prefiltration and effective reduction of dissolved impurities. The first zone removes sand, iron, and particles 10 microns and larger, while the second uses activated coconut carbon enhanced with AQUALEN fibers to reduce particles 3 microns and larger, including heavy metals, pesticides, and pharmaceutical residues.

The RO-70S EU system

The RO-70S EU is a compact, high-performance reverse osmosis system with dual-zone prefiltration and in-tank mineralization. Designed for the whole household, it delivers premium-quality, ultra-pure drinking water with a stable, smooth flow — even at low water pressure from 0.2 MPa / 2 bar. With a capacity of up to 380 L per day, the RO-70S EU delivers crystal-clear water for everyday drinking, cooking, and baby food preparation.

The integrated mineralization system places inside the reservoir, ensuring uniform enrichment of purified water with natural magnesium, final water conditioning, an optimal salt and mineral balance, and improved taste.

Thanks to AQUAPHOR patented technologies, the system is more compact and efficient than traditional reverse osmosis units. The built-in 5 L water-on-water storage tank saves under-sink space and and saves up to 9 tons of water per year.

AQUAPHOR filtration systems effectively reduce PFAS using high-quality activated carbon and advanced ion-exchange materials, including PFOA and PFOS.
