SimPure Q3-600T Reverse Osmosis System - Fast Tankless 600 GPD

Our review of the SimPure Q3-600T finds it best suited for households that want near-zero TDS drinking water and fast on-demand delivery without a bulky storage tank. The Q3-600T's most convincing feature is its combination of an 8-stage filtration path with a 0.0001m RO membrane plus a T33 faucet that further polishes taste and removes chlorine, producing very pure water quickly. Installation requires an under-sink power connection but the system arrives pre-assembled and most users report easy setup and noticeably improved water taste.

Key Features

• 0.0001m RO membrane: Delivers near 0 TDS by removing 99.99% of contaminants including heavy metals and many chemicals for safer drinking water.
• 8-stage filtration: Combines membrane separation and adsorption to reduce small-molecule organics and a wide range of impurities.
• T33 faucet with built-in filter: Acts as a final polishing stage that improves taste and provides near-complete chlorine removal independently of the main unit.
• 600 GPD tankless output: Produces water quickly, filling a 200ml cup in about 8 seconds for continuous use without a storage tank.
• Compact tankless design: Saves under-sink space and arrives pre-assembled with included hoses for faster setup.
• Certified performance: NSF/ANSI 58 certification and SGS testing back the system's contaminant reduction claims for common municipal and well water with TDS under 500 ppm.

Who It's For

This system is ideal for homeowners and families who want very low TDS drinking water, prefer a tankless under-sink unit to save space, and have access to an under-sink power outlet. It suits users who value taste improvement and chlorine removal, and those on rural supplies who need reliable contaminant reduction.

It is less suitable for kitchens without an available dedicated under-sink power source or for users who cannot drill a roughly 2 in sink hole for the faucet. People who only need basic carbon filtration rather than near-zero TDS performance should consider simpler, non-powered filters.

Pros & Cons

Pros

• High filtration quality with an 8-stage system and 0.0001m membrane for broad contaminant removal.
• Fast, tankless 600 GPD output provides continuous water without a bulky storage tank.
• T33 faucet adds independent polishing and near-complete chlorine removal for better taste.
• Pre-assembled unit and included hoses make installation straightforward for most users.

Cons

• Requires an under-sink electrical connection and cannot be plugged into a garbage disposal outlet.
• Faucet installation needs a roughly 2 in hole in the sink, which may limit fit in some setups.

Frequently Asked Questions

Does the unit need electricity?
Yes. The Q3-600T requires an under-sink power connection to operate and cannot be plugged into a garbage disposal outlet.

Will it remove chlorine taste?
Yes. The T33 faucet includes a polishing filter that achieves near-complete chlorine removal and improves water taste.

Can it be used with well water?
It works with water that has TDS under 500 ppm and customers report good performance on some rural supplies, but check your water chemistry if levels are higher.
