Description
A MyWaterClub alkaline inline filter that raises pH up to ~9.5 using a blend of FIR energy balls, natural mineral stone, and alkaline media — designed as the last stage in 3/8″ OD tubing applications or under-sink RO systems. Made in Taiwan.
What it is
This alkaline inline filter is designed as the final stage in an under-sink RO system or any water filtration setup using 3/8″ OD tubing. It contains three types of natural mineral media — far infrared (FIR) energy balls, natural mineral stone, and alkaline media — that work together to raise pH and add trace minerals back into filtered water.
After reverse osmosis strips dissolved solids from your water, this filter restores mineral content and raises the pH up to approximately 9.5 (actual pH depends on your feed water). The result is smoother-tasting water with a slightly alkaline character. The white body and 3/8″ quick-connect ports make installation simple — push-fit onto existing 3/8″ OD tubing as the last stage before the faucet.
Key benefits
- ✓Raises pH up to ~9.5 — restores alkalinity after RO filtration
- ✓Three mineral media — FIR energy balls, natural mineral stone, alkaline media
- ✓Adds trace minerals back into purified water for improved taste
- ✓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
- ✓White body — clean, finished appearance
- ✓Made in Taiwan
Good to know
- pH output varies with your feed water — “up to ~9.5” is typical on low-TDS RO permeate; higher-TDS feed may produce a different result.
- 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 about alkaline water.
