Double Stainless Steel Undercounter Water Filter – 1/2" Tap Connection | OASIS F2-DIRECT INOX

Double Stainless Steel Under-Counter Water Filters with Filter Combination Selection

1. PPF & CTO - Basic Filtration
   1st Filter (PPF): Polypropylene for retention of sediments, dust, rust, and particles up to 5μm.
   2nd Filter (CTO): Activated Carbon in solid form (Carbon Block) for removal of chlorine, chemicals, unpleasant odors and tastes.
   Ideal for: Municipal water or other quality municipal waters that are chlorinated, without salt problems.
2. PPF & RESIN - Salt & Hardness Reduction
   1st Filter (PPF): Polypropylene for retention of sediments and particles.
   2nd Filter (RESIN): Ion exchange resin for reducing water hardness (calcium & magnesium salts), protection from scaling.
   Ideal for: Areas with hard water (high salts), such as islands or areas with groundwater rich in inorganic salts.
3. CTO & RESIN - Odor Removal & Salt Reduction
   1st Filter (CTO): Activated Carbon for removal of chlorine, odors, and chemicals.
   2nd Filter (RESIN): Ion exchange resin for hardness reduction and salt protection.
   Ideal for: Water with strong chlorine odor and high hardness (salts), combining odor removal with softness.
4. PRO-UF & RESIN - Maximum Protection with UF Membrane & Salt Reduction
   1st Filter (PRO-UF): 4-stage filter (PP-CTO-UF) with Ultrafiltration membrane 0.1μm for retention of bacteria, cysts, microorganisms. Also removes sediments and chlorine.
   2nd Filter (RESIN): Ion exchange resin for hardness reduction and salt protection.
   Ideal for: Boreholes, water with microbiological contamination, old water networks, or areas with inadequate chlorination requiring maximum protection and salt reduction.

Important Water Pressure Update

⚠️ Caution: If you are on the 1st floor or lower (ground floor, basement), the water pressure may be very high. The use of a pressure reducer is highly recommended to avoid leaks and damage to the filtration system. The ideal operating pressure is 2-4 bar. Pressure above 6 bar may cause leaks.

Technical Specifications

Filter Replacement Frequency

Recommended filter replacement: Every 6 months, depending on water quality and usage. If you notice reduced pressure or change in water taste, replace earlier.
