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.

• 裝一個多少錢？tester 可以測離子濃度，無法測其它汙染物（比如有機汙染物）。 -欲千北- ♂ 給 欲千北 發送悄悄話 欲千北 的博客首頁 (0 bytes) () 06/07/2016 postreply 16:53:49
