SimPure T1-100ALK Alkaline Reverse Osmosis System - Faster Flow

Our review of the SimPure T1-100ALK finds it best suited for homeowners who want under-sink reverse osmosis water with restored minerals and faster access to filtered water. The single biggest reason to buy is the combination of an alkaline mineral stage and a 2.5-gallon tank with a built-in pump that gives an unusually brisk flow rate for RO systems, making it easy to supply a faucet, refrigerator, or ice maker without long waits. This system is also SGS tested against NSF/ANSI 58 standards and designed to remove a broad range of contaminants while returning useful minerals for improved taste.

Key Features

• 2.5-gallon tank: Provides a ready reserve so filtered water is available quickly and reduces wait times between fills.
• 81 fl.oz/min flow rate: Delivers about 1.3 gallons of filtered water instantly for everyday use and feeding a refrigerator or ice maker.
• NSF/ANSI 58 tested: Certified performance ensures the system removes over 99.99% of 1000+ contaminants for safer drinking water.
• Alkaline mineral stage: Reintroduces calcium, magnesium and potassium to restore natural alkalinity and improve the taste of RO water.
• Built-in pump: Helps maintain pressure so the system performs reliably even with varied household water conditions.
• Quick-change cartridges: Twist-in filters make replacements straightforward and keep maintenance low.

Who It's For

The SimPure T1-100ALK is ideal for kitchen users who want true reverse osmosis purity but prefer water that is slightly alkaline and mineralized for taste. It fits homeowners who need a steady, faster supply to a faucet and refrigeration line and who value an easier twist-filter change process.

Customers who need absolute minimum TDS (near 0 ppm) or who want an ultra-compact countertop unit should look elsewhere; the alkaline stage intentionally leaves some minerals and the tank and pump make this an under-sink installation rather than a portable solution.

Pros & Cons

Pros

• Strong contaminant reduction certified to NSF/ANSI 58 for reliable purification.
• Faster usable flow thanks to the 2.5-gallon tank and built-in pump, convenient for refrigerators and ice makers.
• Alkaline stage returns natural minerals for improved taste and balanced pH.
• Easy DIY installation with quick-connect tubing and twist cartridges lowers service costs.

Cons

• The alkaline stage increases pH but will not produce the lowest possible TDS values for users who want near-zero TDS.
• Under-sink footprint and tank mean it requires installation space and is not portable.

Our Verdict

The SimPure T1-100ALK is a strong choice for homeowners who want certified RO-level purification plus an alkaline mineral finish and faster access to filtered water. It balances contaminant removal, improved flavor, and user-friendly maintenance, offering good value for under-sink installations that supply a faucet and refrigerator line.

Frequently Asked Questions

Can this connect to a refrigerator or ice maker?
Yes, the system is designed to feed a refrigerator or ice maker for a continuous filtered supply thanks to its faster flow and tank capacity.

Will the alkaline stage remove all TDS?
No, adding minerals raises pH and leaves some TDS; choose the non-alkaline T1-100 model if you need near-zero TDS values.

How hard is installation and filter replacement?
Installation is intended for DIY with included quick-connect tubing and the twist-in cartridges make routine replacements straightforward.
