SimPure T2-600T vs T1-400ALK Specs
Daily water capacity
The SimPure T2-600T produces 600 gallons per day, while the T1-400ALK delivers 400 gallons per day. Both systems are designed for under-sink installation. The higher capacity of the T2-600T makes it suitable for larger households or those with higher water usage demands. The T1-400ALK remains efficient for standard family needs. You should choose based on your daily consumption requirements. If you need faster replenishment or serve more people, the T2-600T offers a clear advantage in output volume. Both meet NSF/ANSI 58 standards for quality assurance.
Water efficiency ratio
Efficiency is measured by the pure-to-drain ratio. The SimPure T1-400ALK operates at a 1.5:1 ratio, meaning it produces 1.5 gallons of filtered water for every 1 gallon of wastewater. The SimPure T2-600T has a 2:1 ratio, producing 2 gallons of filtered water per gallon of wastewater. A higher ratio means less water waste during the filtration process. The T2-600T is more water-efficient. This difference matters if you want to minimize household water usage. The T1-400ALK is still efficient, but the T2-600T performs better in this specific metric.
Filtration technology
The T1-400ALK uses an alkaline remineralization filter to add minerals like calcium, magnesium, and potassium. This raises the pH level of the water. The T2-600T uses UV filtration to provide near 0 TDS water, removing dissolved solids. The T1-400ALK does not reach 0 TDS. The T2-600T is better for those who want pure, mineral-free water. The T1-400ALK is better if you prefer mineral-enriched water. Your choice depends on whether you prioritize pH balance or absolute purity. Both systems remove over 99.99% of contaminants.
Tank design
The SimPure T1-400ALK is a tankless system. It does not use a storage tank, which saves under-sink space and prevents secondary contamination. The SimPure T2-600T includes a built-in pressure tank. This design ensures stable water pressure and a consistent flow rate of 0.42 GPM. The tank allows for direct connection to refrigerators and ice makers without pressure drops. If you need steady pressure for appliances, the T2-600T is superior. If you prefer a compact, tankless setup, the T1-400ALK is the better option.
Physical dimensions
Both units are compact for under-sink installation. The T1-400ALK measures 15.6 inches in length, 5.3 inches in width, and 15.7 inches in height. It weighs 17.6 pounds. The T2-600T measures 15.5 inches in length, 5.3 inches in width, and 16.3 inches in height. The width is identical for both models. The T1-400ALK is slightly shorter in height but includes a weight specification. The T2-600T is slightly taller. The difference in height is minimal. Both fit standard under-sink cabinets. The weight of the T2-600T is not listed in the provided data.
Which SimPure System Fits Your Needs
Users wanting near-zero TDS for sensitive appliances
The T2-600T reduces tap water TDS to below 25 ppm. This near-zero mineral content is ideal for coffee makers, ice machines, and humidifiers. The built-in tank ensures stable flow at 0.42 GPM. You get consistent pressure without an external tank, making installation easier for direct line connections.
Drinkers preferring mineral-enriched alkaline water
The T1-400ALK adds calcium, magnesium, and potassium to raise pH. It does not reach zero TDS, which suits those who want mineral taste. The tankless design saves space under the sink. You get fresh water on demand with a 1.5:1 pure-to-drain ratio, reducing wastewater compared to older systems.
Households prioritizing high daily water capacity
With 600 GPD capacity, the T2-600T produces water twice as fast as the 400 GPD T1-400ALK. It features a 2:1 filtered-to-drain ratio, which is more efficient than the T1's 1.5:1 ratio. This system handles high demand better, making it suitable for large families or heavy usage.

Yes, the T1-400ALK includes an alkaline filter stage. This feature raises the pH level and adds beneficial minerals back into the purified water. You get a more balanced taste compared to standard RO systems. It suits those who prefer mineral-rich drinking water over near-zero TDS output.
Is the SimPure T2-600T UV system tankless?
No, the T2-600T uses a built-in storage tank. The data indicates it delivers stable flow at 0.42 GPM, which requires a tank to maintain pressure. In contrast, the T1-400ALK is explicitly designed as a tankless unit. Choose the T2-600T if you need high volume with consistent pressure.
Which model is better for a large family?
The T2-600T is better for large families due to its higher capacity. It produces 600 gallons per day, compared to the 400 gallons per day of the T1-400ALK. This higher output supports greater daily usage. It also features UV filtration for added safety in high-volume households.
Do both systems remove contaminants like PFAS?
Yes, both systems are certified to NSF/ANSI 58 standards. They remove over 99.99% of contaminants, including heavy metals and PFAS. You can rely on either model for safe drinking water. The choice depends on whether you prioritize mineral addition or higher daily output.
How wide are the SimPure systems?
Both units have a width of 5.3 inches. The T1-400ALK measures 15.6 inches in length and 15.7 inches in height. The T2-600T measures 15.5 inches in length and 16.3 inches in height. Both fit standard under-sink cabinets. The T1-400ALK weighs 17.6 pounds.
Does the T2-600T use UV light for purification?
Yes, the T2-600T includes UV filtration as a key feature. This adds an extra layer of protection against bacteria and viruses. The T1-400ALK does not list UV filtration. If you want UV disinfection alongside reverse osmosis, the T2-600T is the correct choice.
