The Reverse Osmosis System easily attaches to your kitchen faucet without the need for a plumber. Ideal portable solution for your apartment, home, RVs, aquarium or during your travel time.
This advanced 5-Stage Ultra-Pure Reverse Osmosis (RO) System delivers exceptionally high-quality drinking water by combining
multiple layers of filtration, including a special polishing stage that produces ultra-pure water. It connects easily to your kitchen faucet
without the need for a plumber or permanent installation, making it ideal for apartments, homes, RVs, aquariums, and travel.
While a 4-stage RO system effectively removes sediment, chlorine, chemicals, and dissolved solids, this 5-stage system adds an extra
polishing stage that significantly improves water purity. The additional stage delivers ultra-low TDS (total dissolved solids) output, bringing
your water closer to true ultra-pure quality. 1
The added polishing stage further reduces trace contaminants, resulting in cleaner, more refined water than standard 4-stage systems. 1
Stage 1 – Sediment Filtration (5 Micron)
Premium quick-connect sediment filter captures dust, sand, rust, and other large particles to protect downstream media.
Stage 2 – Coconut Shell Activated Carbon (T28)
Reduces chlorine, taste, odor, VOCs, and many common organic chemicals from your source water.
Stage 3 – Reverse Osmosis Membrane (TFC)
High-rejection RO membrane removes a high percentage of dissolved solids and contaminants, including heavy metals and harmful elements.
Stage 4 – Deionizing (DI) Mixed Bed Polishing Filter
This stage further lowers total dissolved solids and removes trace ions for ultra-pure water quality.
Stage 5 – Premium Coconut Carbon (T33) Finish Filter
Final polishing filter improves taste and provides the crisp, clean finish you expect from premium RO systems.
Both options deliver the same ultra-pure filtration performance. Higher GPD membranes simply produce water faster based on usage and conditions.
☑ Ultra-pure water quality with 5-stage filtration
☑ Installs in under 60 seconds — no plumbing required
☑ Removes or significantly reduces more than 1000 contaminants
☑ Produces cleaner water than standard 4-stage systems
☑ Fluoride reduction: approximately 85%–90%
☑ Operating cost approx. 6–7¢ per gallon
☑ Produces 3–5 gallons per hour
☑ Designed and assembled in the USA (California)
☑ 30-day satisfaction guarantee
Typical service life: 8–12 months or approx. 1,000 gallons (varies with source water quality and usage).
After regular use (about 5–7 days), water with source TDS around 350 ppm may drop to approximately 0–20 ppm with the
Ultra-Pure version, or 30–60 ppm with the Remineralized version.
The RO purification process is slow and drip-style rather than a flowing stream. We recommend collecting purified water in advance
so you always have clean water on hand.
Filtration accuracy ~0.0005 microns (RO membrane).
Product dimensions: 14″ × 6″ × 7″
Weight: approx. 6 lbs
This system supports multiple connection types:
Actual filter life and performance can vary based on water quality, pressure, and usage. RO systems require regular maintenance
and annual filter replacement to maintain optimal results.
