Description
A MyWaterClub remineralization inline filter that enriches purified water with trace minerals and gently raises pH to 7.5–8.3 — four natural media, 3/8″ quick-connect, ~400-gallon capacity. Made in Taiwan.
What it is
This remineralization inline filter is designed as the final stage in an under-sink RO system or any filtration setup using 3/8″ OD tubing. After reverse osmosis strips dissolved solids, this filter adds beneficial trace minerals back and gently raises pH to a natural 7.5–8.3 range — restoring the taste and mineral profile that RO removes.
Inside the housing are four types of natural media: far infrared (FIR) ceramic media, coral red stone, maifan stone, and bioceramic media balls. Together they slowly release calcium, magnesium, potassium, and other trace minerals as water passes through. The result is smoother, more natural-tasting water at a gentle, near-neutral pH — not strongly alkaline.
Key benefits
- ✓Enriches water with trace minerals — Ca, Mg, K, and more from four natural media
- ✓Gently raises pH to 7.5–8.3 — restores natural balance after RO
- ✓Four media blend — FIR ceramic, coral red stone, maifan stone, bioceramic balls
- ✓~400-gallon capacity — approximately 6–12 months depending on usage
- ✓Final-stage design — install after RO or carbon for best results
- ✓3/8″ quick-connect — push-fit onto 3/8″ OD tubing, no tools needed
- ✓Made in Taiwan
- ✓Automatic quantity discounts
Good to know
- pH output is gentle (7.5–8.3) — this is a remineralizer, not a high-alkaline filter. If you want stronger alkalinity (pH ~9+), see the Alkaline filter.
- This filter is designed for 3/8″ OD tubing. If your system uses 1/4″ tubing, you’ll need a 1/4″-to-3/8″ adapter or choose a 1/4″ version.
- We describe this filter in taste and mineral terms and do not make health claims.
