Choosing the right pure water system model for your family requires considering water quality, family size, water usage needs, and installation conditions. Here are some targeted selection suggestions:
1. Choose a basic configuration based on your family's water quality:
For ordinary town tap water: Prioritize an RO reverse osmosis water purifier, which effectively removes heavy metals, bacteria, viruses, and soluble salts, ensuring safe drinking water.
For high-hardness water (hard water areas): A combination of a pre-filter + central water softener + point-of-use RO water purifier is recommended to alleviate limescale problems, protect appliances, and improve the washing and care experience.
2. Match the flow rate according to family size and water consumption:
For small families of 1-3 people/renters: Choose a model with a flow rate of 600G-800G, which fills a glass of water in about 10 seconds, meeting daily drinking and simple cooking needs. For example, the Midea Baize 600G Pro has a slim design and is easy to install, making it suitable for small spaces.
For families of 5 or more/villa users: We recommend models with a flow rate of 1000G or higher, achieving a water output speed of 3L/min or more. This allows for simultaneous use in multiple scenarios such as soup making, vegetable washing, and direct drinking without queuing. For example, the A.O. Smith Blue Whale 3.0 Ultra (1500G) has a tested water output of 3.84L/min.
3. Focus on Core Performance and Operating Costs
Filter Life: Prioritize products equipped with long-life RO membranes, such as the Smith MAX10.0 side-flow RO membrane, which the company claims requires no replacement for 10 years, reducing long-term maintenance costs.
Water Saving Performance: Choose models with 5A Level 1 water-saving certification, with a wastewater ratio better than 2:1, avoiding water waste.
First Cup of Water TDS: Pay attention to whether the model has "zero stagnant water" or "all-time pure water" technology, ensuring that the first cup is safe to drink after being left overnight, especially suitable for families with infants.
4. Consideration for Ease of Installation and Maintenance
Limited Under-Sink Space: Choose a compact model with a filter thickness ≤160mm, such as the Midea Baize series (only 140mm).
Ease of Maintenance: Prioritize models with an integrated quick-connect filter design, allowing for easy replacement without specialized tools, ideal for renters who frequently move.
Smart Reminder Function: Some high-end models support app monitoring of filter lifespan, water consumption, and water quality, enhancing the user experience.
