What Is Alkaline Water and Why Does It Matter?
Alkaline water has a higher pH level than regular tap water and often contains beneficial minerals like calcium, potassium, and magnesium. Many people believe that drinking alkaline water can help neutralize acid in the body, improve hydration, and support overall wellness.
Advantage of alkaline water:
- May aid in acid reflux relief
- Better hydration due to smaller water clusters
- Potential antioxidant properties
- Enhances detoxification
- Supports better bone health with trace minerals
While science continues to explore the full benefits, millions have turned to alkaline water as a proactive way to support a healthier lifestyle—and the Smarths RO-1 makes it easy to enjoy right at home.
Four-Stage Filtration Technology
The Smarths RO-1 uses a streamlined four-stage process to deliver purity that rivals five-stage systems—with fewer filter replacements and lower maintenance costs:
- HDG-SED5 – Sediment Pre-Filter: Captures dirt, sand, rust, and debris.
- HDG-CB5 – Carbon Block Filter: Removes chlorine, bad taste, odors, and organic chemicals.
- HDG-TW50 – Reverse Osmosis Membrane: Eliminates up to 99% of TDS (Total Dissolved Solids), including heavy metals, fluoride, and microbes.
- HDG-CB5P – Post-Carbon Filter: Final polishing stage for better flavor and odor control.
This configuration provides a balanced combination of protection and performance, all in a space-saving design.
Is Tap Water Safe to Drink?
Many homeowners ask, is tap water safe to drink? The answer depends on your local supply. While most municipal water systems are regulated, they can still contain trace amounts of:
- Chlorine and disinfectant byproducts
- Lead from old plumbing
- Nitrates from agriculture
- Microplastics and PFAS (forever chemicals)
- Pharmaceuticals and hormone residues
The Smarths RO-1 gives you peace of mind with every glass. It’s not just about removing visible particles—it’s about protecting your family from the contaminants you can’t see.
