Description

Purpose: Increases pH level of RO water to approximately 8.4–9.3, improving taste and adding beneficial alkaline properties. Drinking alkaline water helps restore natural mineral balance after filtration, supports optimal hydration, and improves taste. A higher pH may help neutralize acidity in the body, support digestion, reduce acid reflux symptoms, and promote overall wellness with smoother, more refreshing drinking water.

Ideal For:

• Countertop and under-sink RO systems (as a final stage)

• Alkaline drinking water

• Applications requiring enhanced mineral balance and smoother taste

• Use after RO membrane and carbon polishing filter (T33)

Content / Media Composition:

• Calcite (Calcium Carbonate) – adds essential calcium & stabilizes pH

• FIR (Far Infrared Ceramic Balls) – improves water structure and absorption

• Alkaline Ceramic Balls – enhances alkalinity and raises pH

• Tourmaline Balls – contributes to ORP reduction and mineralization

• Magnesium Media – naturally boosts pH and adds trace minerals

Flow Direction: Water enters from IN and exits from OUT toward faucet or dispensing line. Used as the last stage in RO systems.

🔧Installation Tips

Tubing Size

• Most RO systems use 1/4″ OD tubing (standard RO size).
• Some countertop RO systems and specialty setups use 3/8″ OD tubing.
• Tubing size refers to the outside diameter (OD) of the tube.

When Do You Need Elbow Adapters?

• Select 3/8″ OD Tubing if your system uses larger tubing.
• We include 2 elbow adapters to connect the inline filter to 3/8″ OD tubing.

✔ No tools required
✔ Push-to-connect installation

When Do You Need a T-Fitting?

A T-fitting (1/4″ stem x 1/4″ OD Tubing x 1/4″ OD Tubing) is helpful if you are:

• Adding the inline filter to an existing 1/4″ RO line
• Want an easier install with a clean branch connection
• Installing between tubing lines without reworking your layout

✔ Optional accessory
✔ Makes installation easier for some setups

Not Sure Which Option to Choose?

• If unsure, select 3/8″ OD Tubing. The filter comes with 1/4″ connections, and we include two elbow fittings for 3/8″ OD tubing in the package.
• Message us before ordering—we’re happy to help you pick the right fittings.

▶️ Video Installation Guidance

Because RO systems and plumbing layouts can vary, there are multiple valid ways to install an inline filter.

If you are unsure about your setup, we recommend:

• Searching YouTube for “inline RO filter installation”
• Watching a video that best matches your system type
  (under-sink RO, countertop RO, post-filter installation, etc.)

Visual step-by-step videos can be very helpful and often make installation easier and faster.
