Berkey Water Purifiers
I ordered the fluoride Berkey water filters from LPC because the silly city I live in fluoridates. LPC had them for a good price. When I ordered with the wrong shipping address I was able to call and quickly change it no problem.
I too bought some Berkey Sports for when traveling. Love this product and have used it traveling all over the world. No problems getting it through TSA.
These guys are hilarious! Met them at the last expo and it was a riot of a time. They really know water filters too!
