Reverse Osmosis 6-Month Replacement Kit

Puragain Reverse Osmosis Replacement Filter Set

Keep your reverse osmosis system performing at its best with fresh Puragain replacement filters.

The Puragain Reverse Osmosis Replacement Filter Set includes the essential filtration components used to maintain the performance, water quality, and taste of your reverse osmosis drinking water system.

This replacement package includes a Sediment Filter, Granular Activated Carbon (GAC) Filter, Carbon Block Filter, and Reverse Osmosis Membrane—providing multiple stages of filtration before water reaches your drinking faucet.

Sediment Filter

The first line of defense for your RO system.

The sediment filter helps capture suspended particles such as dirt, sand, rust, silt, and other sediment before they reach the carbon filters and RO membrane.

Regular replacement helps protect downstream filtration components and maintain proper water flow.

GAC Carbon Filter

The Granular Activated Carbon (GAC) stage helps reduce chlorine and unwanted tastes and odors while conditioning the water before it reaches the RO membrane.

Removing chlorine is especially important because it can negatively affect many types of RO membranes over time.

Carbon Block Filter

The carbon block provides an additional stage of carbon filtration, helping further reduce chlorine, tastes, odors, and certain organic compounds while providing finer filtration before the water reaches the membrane.

Together, the GAC and carbon block stages help protect the RO membrane and improve the overall quality of the finished water.

Reverse Osmosis Membrane

The heart of the reverse osmosis system.

The RO membrane uses an extremely fine semipermeable barrier to separate purified water from many dissolved substances found in the incoming water supply.

Depending on the membrane specifications and incoming water conditions, reverse osmosis can significantly reduce total dissolved solids (TDS) and a broad range of dissolved impurities.

What's Included

✓ 1 Sediment Filter — Helps capture dirt, rust, sand and sediment
✓ 1 GAC Carbon Filter — Helps reduce chlorine, taste and odor
✓ 1 Carbon Block Filter — Additional carbon filtration and membrane protection
✓ 1 Reverse Osmosis Membrane — Primary purification stage for reducing dissolved substances

Protect Your System. Maintain Your Water Quality.

Filters are consumable components and gradually lose effectiveness as they process water. Replacing them at the recommended intervals helps maintain water quality, system flow, RO membrane performance, and great-tasting drinking water.

Fresh filters. Better performance. Better water.

Puragain Water — Better Water Starts at Home.

Replacement frequency varies based on household water consumption, incoming water quality, pressure, TDS, chlorine concentration, and system specifications. Specific contaminant-reduction claims depend on the individual filter and membrane performance specifications and applicable certifications.
