Complete replacement set for the 5-Stage Alkaline system
This replacement set is designed for 5-Stage Alkaline MyWaterClub Countertop Reverse Osmosis systems. It includes all five filters — sediment, pre-carbon, RO membrane, post-carbon, and the 3-in-1 alkaline mineral stage — so you refresh the entire system in one purchase. This is the complete set with a new RO membrane, recommended roughly every 24 months.
Need the annual set without a membrane? If you replaced your membrane last year and only need the pre-filters, post-filter, and alkaline stage, choose the annual alkaline 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 — Post-Carbon
Quick-Connect T33 Coconut Carbon
Final carbon polishing that improves taste and odor after RO filtration, before the alkaline stage.
Stage 5 — Alkaline
3-in-1 Alkaline Mineral Post-Filter
Adds minerals back and raises pH to roughly 8.0–9.5 for taste. Multi-media blend: alkaline mineral, ORP ceramic, tourmaline, and calcite.
About the alkaline stage
The 3-in-1 alkaline post-filter adds mineral content back into the purified water and raises pH to approximately 8.0–9.5, giving the water a rounder taste and mouthfeel than flat RO water. Its mineral-ball media can also shift the measured oxidation-reduction potential (ORP) into a negative range. These are measurable properties of the water — we describe the alkaline stage in taste and mineral terms and don’t make health claims about alkaline or ORP water.
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).
- TDS reading note: because the alkaline stage adds minerals back, your TDS meter will read higher than it would after a plain RO system. That’s expected and does not mean the set is underperforming.
- 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.
