5-Stage Ultra-Pure RO
Complete replacement set for the 5-Stage Ultra-Pure system
This replacement set is designed for 5-Stage Ultra-Pure MyWaterClub Countertop Reverse Osmosis systems. It includes all five filters — sediment, pre-carbon, RO membrane, DI ion-exchange, and post-carbon — so you refresh the entire system in one purchase. This is the complete set with a new RO membrane, recommended roughly every 24 months.
The DI (deionization) stage is what makes this an ultra-pure set: after the RO membrane, it captures remaining dissolved ions to drive total dissolved solids (TDS) to the lowest possible level — ideal for applications that need near-zero TDS water.
Need the annual set without a membrane? If you replaced your membrane last year and only need the pre-filters, DI stage, and post-filter, choose the annual ultra-pure set instead (linked below).
What’s included (5 filters)
Stage 1 — Sediment
Quick-Connect 5 Micron Sediment
Traps dust, dirt, rust, and sediment. Protects downstream filters and extends the life of the system and membrane.
Stage 2 — Pre-Carbon
USA-Made T28 Coconut Carbon
Reduces chlorine and chemical contaminants, improves taste and odor, and helps protect the RO membrane.
Stage 3 — RO Membrane
RO Membrane — 100 or 150 GPD
High-performance membrane for purified drinking water. Choose 100 or 150 GPD to match your system.
Stage 4 — DI Polish
Omnipure K2555-BB DI Ion Exchange
Deionization stage captures remaining dissolved ions after RO, driving TDS to the lowest possible level for ultra-pure water.
Stage 5 — Post-Carbon
Quick-Connect T33 Coconut Carbon
Final polishing stage that improves taste and odor after the DI stage.
Choose your membrane: 100 or 150 GPD
Pick the same GPD your system currently uses. Both deliver the same purification quality — the higher GPD simply produces water faster.
Two ways to buy: Filter Set or Pre-Assembled
Select one option at checkout depending on how quickly and easily you want to swap:
Option 1 — Filter Set Only
- Replacement filters only
- Replacement time: 30–40 minutes
- Difficulty: Moderate
- Best value — reuses your existing fittings, clips, and housing
Option 2 — Pre-Assembled Assembly
- Fully assembled set with new fittings, clips, membrane, and housing
- Swap the whole assembly in about 1 minute
- Reconnect just two tubes (kitchen diverter to assembly)
- Difficulty: Easy — the fastest, cleanest way to refresh

Good to know
- A step-by-step filter replacement guide for 5-stage RO is included — look for the printable manual on this page.
- Match the membrane GPD to your current system (100 or 150 GPD).
- After installing a new membrane, run and discard the first batch of water, then let the system produce for a few days before relying on your TDS reading — new membranes settle in.
- The pre-assembled option is worth it if you’d rather not disassemble filters yourself — two tubes and you’re done.
Please note: Filter life and reduction performance depend on your water chemistry, pressure, and usage, so results vary from home to home. Replacement intervals are general guidance, not a guarantee. When in doubt, test your water or ask us and we’ll help you choose the right set.
