Stokk RS1-PPC Filter for S1, S1 Plus & S1 Pro – Replacement, 6–12 Month Lifetime

Premium replacement filter for the S1 family

Designed for the S1, S1 Plus, and S1 Pro reverse osmosis systems, the RS1-PPC combines a robust pre-filter with a coconut-shell activated carbon stage to help you maintain purified water at home. This dual-stage approach targets a broad range of particulates and common water odors, supporting your filtration system’s efficiency.

Key components and materials include a premium polypropylene pre-filter that captures larger particles and a coconut-shell activated carbon post-filter that reduces odors and chlorine residues. Together, they work to enhance taste, clarity, and overall water quality while helping protect downstream RO membranes.

• Compatible Model: Specifically designed for the S1, S1 Plus, and S1 Pro RO system, ensuring a secure fit.
• Enhanced Filtration Performance: The PPC design blends pre-filter and post-carbon filtration to remove particulates, odors, and chlorine-related byproducts.
• Premium Materials: The pre-filter uses polypropylene; the carbon stage uses coconut-shell activated carbon for effective contaminant reduction.
• Long-lasting Durability: Replace every 6–12 months depending on usage for sustained filtration.
• Effortless Installation: Twist-to-replace design enables quick, clean maintenance.

In everyday use, the RS1-PPC filter can support a steady supply of water for coffee, tea, cooking, and hydration. You may notice crisper flavors in beverages and a more neutral taste in water, especially in homes with chlorinated supply or noticeable odors. The filter is designed to work with your S1 system to help maintain filtration performance over time.
