more on lead regarding brita filter

[montalcino99]

Hi. I have a brita OB03 filter that indicates "reduces 99% lead at pH 6.3". So, if I run multiple filters in series, each time the input water being the output of the previous filter, will the filter continue to reduce the lead content by 99%. That is, will the filtering "compound"? With hypothetical numbers with large numbers for clarity, if the water starts with 1,000,000 parts lead then after one filter it will contain 10,000 parts. After a second filtering, it will contain 100 parts, and so on..

This seems like a simplistic specification. I suspect there is a limit to the filtering capability. A more clear spec would say something to the effect that the maximum lead content would not exceed xx ppm....

My wife is pregnant and I'm trying to figure out how to get the lead content of her drinking water as low as possible.
