Under Sink Reverse Osmosis System 600 GPD Tankless

Is Your Tap Water Really Safe to Drink?

Chlorine, heavy metals, sediment, and dissolved solids are common in US tap water — and standard filters barely scratch the surface. The Under Sink Reverse Osmosis System 600 GPD from Smart Living Co. delivers hospital-grade 8-stage filtration right from your kitchen faucet, removing up to 99% of contaminants for water that tastes as clean as it looks.

8-Stage Deep Filtration for Pure, Great-Tasting Water

This tankless RO system combines a high-performance RO membrane with a PPC composite filter across 8 filtration stages — each one targeting a different class of contaminant. Sri Lankan coconut shell activated carbon enhances taste and removes residual odors, so every glass is crisp and refreshing.

Why US Homeowners Choose It

• 600 GPD High-Flow Capacity: Delivers up to 600 gallons of purified water per day — enough for large families, home offices, and even small restaurants. No waiting, no slow trickle.
• Tankless Space-Saving Design: At just 15.63 × 5.39 × 13.66 in, this compact system saves 75% of under-sink space compared to traditional tank-based RO systems. No bulky storage tank, no secondary contamination risk.
• 2:1 Pure-to-Drain Ratio: Conserves 800% more water than conventional RO systems. For every 2 gallons of purified water produced, only 1 gallon is discharged — better for your wallet and the environment.
• Smart TDS Display Faucet: The included smart faucet shows real-time TDS (Total Dissolved Solids) readings so you can monitor your water quality at a glance. Fits standard 1/4″ inner / 1-1/4″ outer faucet holes.
• Long-Lasting Filters: RO filters last up to 2 years; PCF filters up to 1 year. Twist-in design with automatic flushing reduces sediment buildup and extends filter life — fewer replacements, lower long-term cost.
• Quick 30-Minute Installation: Seamless leak-reduction design and straightforward setup means most US homeowners can install it themselves in under 30 minutes. No plumber required.
• Ultra-Quiet Operation: Runs silently under your sink without disrupting your kitchen environment.
• Fast 3–5 Day US Shipping: Ships from our US warehouse directly to your door. Free shipping delivered nationwide — from California to New York.
