 What is difference for RO filters 50G, 100G, 500G, and 1000G water purifier?

G (gallons) represents the continuous water production capacity of the water purifier over a 24-hour period. The higher the value, the faster the flow rate of the output water. However, the cost of purchasing and replacing the filter media is also higher. 50G/100G falls under the category of small-capacity (typically requires a water storage tank), while 500G/1000G belongs to the category of high-capacity (no tank required; water is filtered and ready to drink immediately).

Comparison of key parameters.

Specifications Daily water production capacity (approx.) Actual flow rate (approx.) Typical configuration Water collection experience (1.5L water bottle)

50G 189.5 L 0.13 L/min With pressure tank Very slow; requires waiting for water production or drawing water from the tank.

100G 378.5 L 0.26 L/min With pressure tank Slow; direct water connection requires long waiting time.

500G 1895 L 1.31 L/min No tank Faster; it takes approximately a little over a minute to fill a pot.

1000G 3790 L 2.63 L/min No tank Extremely fast; fills a pot in approximately 30-40 seconds.

An analysis of the key differences.

Water storage methods and space: The 50G and 100G models, due to their slow water-making process, require the use of pressure water storage tanks, which occupy kitchen space and pose a risk of secondary contamination within the tank. The 500G and 1000G models, with their faster flow rates, can be designed without tanks, saving space and ensuring fresher water quality.

Usage scenarios: Small flow rates (50G/100G) are suitable for households with scattered water points, low requirements for instant water availability, or limited budgets. Large flow rates (500G/1000G) are suitable for multi-person households with frequent and immediate water needs for activities like tea-making or cooking, aiming for the experience of having water available at the touch of a faucet.

Cost Differences: The larger the flow rate, the higher the costs for RO membranes and pump bodies, leading to a significant increase in the purchase price and the cost of replacing filter cartridges later on. The annual consumption of filter cartridges for a 1000G unit is typically several times that of a 50G unit.

Purification Effect: Under the same conditions of RO membrane material, the size of the flow rate does not affect the final purity of the water; it only influences the rate of water production. However, if the original water’s TDS value is extremely high (> 150 mg/L), smaller-flow units with containers may sometimes be better at ensuring the stability of the output water due to the longer water production cycle.
