TDS是35,现在却是25了。怎么回事?是不是可以继续不换filter? |

protects the RO Membrane. |

that's a fair number to see how well the RO system working. |
i***l 发帖数: 468 | 4 普通水龙头的TDS现在是220,一年前大概是225,基本没变。水的taste没法对照。 |
m********n 发帖数: 3812 | 5 so if TDS is the only standard you worry about, then don't change because it
's still good. |
