I bought HM Digital TDS-EZ Tester from Amazon, and found the TDS (Total Dissolved Solids) in unit of PPM (Part Per Million) is 496 PPM in our tap water. I got scared, and installed Reverse Osmosis filter in one week. 

After I installed the filter, TDS becomes 15-18 PPM. 

I tested bottle water, TDS is 16 PPM. The water came out of my refrigerator filter is 485 PPM, this filter is useless. The same for pitcher water filter.

• 装一个多少钱？tester 可以测离子浓度，无法测其它污染物（比如有机污染物）。 -欲千北- ♂ 给 欲千北 发送悄悄话 欲千北 的博客首页 (0 bytes) () 06/07/2016 postreply 16:53:49

• 谢谢分享，个人感觉，很不错，价钱比我想象的便宜太多了，值。 -欲千北- ♂ 给 欲千北 发送悄悄话 欲千北 的博客首页 (0 bytes) () 06/09/2016 postreply 07:49:29
