The Mineral Problem with Modern Water Filtration

Reverse osmosis systems have become the gold standard for water purification, and for good reason—they remove 99% of contaminants. But there's a catch: they also remove beneficial minerals like calcium, magnesium, sodium, and potassium that your body needs.

This creates a dilemma. You want pure water free from contaminants, but you also need the essential minerals that support bone health, muscle function, nerve transmission, and countless other biological processes. The solution? Remineralization and alkaline filtration.

What is Alkaline Water?

Alkaline water has a pH level above 7.0, typically ranging from 8.0 to 9.5. The pH scale measures how acidic or alkaline a substance is, with 7.0 being neutral. Most tap water sits around 6.5-7.5, while purified RO water can drop to 5.0-6.0 due to mineral removal.

Why pH Matters

Your body maintains a tightly controlled pH balance, particularly in your blood (7.35-7.45). While drinking alkaline water won't dramatically change your blood pH (your body has powerful buffering systems), it can:

• Provide essential minerals in an easily absorbed form
• Support proper hydration
• Neutralize acidic waste products from metabolism
• Improve taste compared to acidic or mineral-depleted water

The Essential Minerals Your Water Should Contain

Calcium

Critical for bone health, muscle contraction, nerve function, and blood clotting. Water is an excellent source of bioavailable calcium that your body can easily absorb.

Magnesium

Involved in over 300 enzymatic reactions in your body. Supports muscle and nerve function, blood sugar control, blood pressure regulation, and protein synthesis. Many people are deficient in magnesium, making water-based supplementation valuable.

Potassium

Essential for heart function, muscle contractions, and maintaining proper fluid balance. Works in conjunction with sodium to regulate blood pressure and cellular function.

Sodium

While often demonized, sodium in appropriate amounts is essential for nerve transmission, muscle function, and maintaining proper fluid balance. Natural mineral water provides sodium in balanced proportions.

The NU Aqua 8 Stage Approach: Purify Then Remineralize

The NU Aqua 8 Stage Alkaline Mineral Countertop Water Filter takes a comprehensive approach: remove contaminants, then add back beneficial minerals. Here's how each stage works:

Stage 1: AG+ Antibacterial Fiber (Nano Silver)

Advanced nano silver technology prevents bacterial growth and strengthens resistance against fungus. This ensures your filter stays clean and doesn't become a breeding ground for microorganisms.

Stage 2: KDF Technology

KDF (Kinetic Degradation Fluxion) uses a high-purity copper-zinc formulation to:

• Eliminate algae and fungi
• Control bacterial growth
• Remove chlorine, pesticides, and organic matter
• Reduce heavy metals like lead, mercury, and arsenic
• Eliminate rust and iron
• Remove unpleasant taste and odor

Stage 3: Coconut Shell Activated Carbon

Premium activated carbon sourced from coconut shells provides superior absorption compared to coal-based carbon. It effectively removes:

• Chlorine and chloramines
• Chemical contaminants and impurities
• VOCs (volatile organic compounds)
• Taste and odor compounds
• Pharmaceutical residues

Stage 4: ORP Balls (Oxidation Reduction Potential)

ORP balls reduce oxidation in water, creating powerful antioxidant properties. This helps:

• Neutralize free radicals
• Support healthy cell function
• Promote proper metabolism
• Improve water's ability to hydrate at the cellular level

Stage 5: Bio-Ceramic

Bio-ceramic materials ionize and activate water molecules, making water more bioavailable. This process:

• Breaks down water molecule clusters for better absorption
• Improves hydration efficiency
• Supports blood circulation
• Enhances overall health when consumed regularly

Stage 6: Mineral Stone Remineralization

This is where the magic happens. Natural mineral stones add back essential minerals that were removed during filtration or are lacking in your source water:

• Calcium for bone health and muscle function
• Magnesium for enzymatic reactions and nerve function
• Sodium for fluid balance and nerve transmission
• Potassium for heart health and blood pressure regulation

These minerals are added in proportions similar to natural mineral springs, creating water that's both pure and nutritionally beneficial.

Stages 7-8: Dual Mesh Filter Screens

Top and bottom mesh screens prevent larger particles and contaminants from entering your water, providing final polishing and ensuring maximum purity.

Countertop Convenience: No Installation Required

One of the biggest barriers to water filtration is installation complexity. The NU Aqua 8 Stage system eliminates this entirely:

Simple Setup

1. Attach the quick-connect faucet adapter to your sink faucet
2. Connect the flexible water line to the filter housing
3. Turn on your faucet and enjoy filtered, mineralized water from the onboard faucet

No drilling, no mounting, no plumbing modifications. When you need to use your sink for cleaning, simply detach the adapter. Reattach it when you want filtered drinking water.

Perfect for Renters

If you rent and can't modify your plumbing, countertop filters are ideal. Take it with you when you move—no permanent installation to undo.

Portable and Flexible

Moving the filter between different faucets is easy. Use it in the kitchen for drinking water, then move it to the bathroom for face washing or other uses.

Performance Specifications

Filter Lifespan

The 8-stage filter cartridge lasts approximately 700 filtration cycles, which translates to 4-8 months depending on usage. For a family of four using it for drinking water and cooking, expect 6 months of service.

Flow Rate

At 0.75 GPM (gallons per minute), the NU Aqua provides adequate flow for filling glasses, water bottles, and cooking pots. While slower than your tap, the flow is faster than many pitcher filters and provides continuous filtration without waiting for a reservoir to fill.

Contaminant Removal

The system effectively removes:

• Chlorine and chloramines
• Heavy metals (lead, mercury, arsenic, chromium)
• Sediment and particulates
• Rust and iron
• Pesticides and herbicides
• VOCs and chemical contaminants
• Bad taste and odor
• Bacteria and fungi (prevented from growing in the filter)

The Health Benefits of Mineralized Alkaline Water

Better Hydration

Mineralized water with smaller molecular clusters (from bio-ceramic treatment) hydrates more effectively at the cellular level. Athletes and active individuals often report feeling better hydrated when drinking mineralized alkaline water.

Bone Health Support

Calcium and magnesium from water are highly bioavailable. Regular consumption of mineralized water contributes to daily mineral intake, supporting bone density and strength.

Cardiovascular Support

Magnesium and potassium play crucial roles in heart health and blood pressure regulation. Water-based mineral supplementation provides these nutrients in an easily absorbed form.

Improved Taste

Mineral-rich alkaline water simply tastes better than demineralized or acidic water. The minerals provide a clean, refreshing taste that encourages you to drink more water throughout the day.

Antioxidant Properties

The ORP balls create water with antioxidant potential, helping neutralize free radicals and supporting overall cellular health.
