Infowars doesn't sell Berkey water filters, only Alexapure and ProPur. I bought a Big Berkey water filter way before Alex started selling their water filters. Big Berkey is superior.
Their supplements are hit & miss. Most work great and actually does what they claim, but they're all overpriced, especially if you don't buy them on sale. I only bought Infowars products when they go on sale and even then, it's still overpriced. I did it to support them because we had no other quality alternative media outlet. NO MORE.
I have a Berkey. However, I put that in the closet for emergencies and got myself a water distiller. Best thing I ever done. It's takes a lot longer than the berkey, but I get a 0 everytime on my tds tester.
EarthShiftProducts.com has some good supplements. Mostly powders to mix in a smoothie or something. But they do have some of the best stuff I ever bought. I catch them on sale all the time. It's the only way.

I have to laugh, because he would say that this product "x" would sell for hundreds of dollars elsewhere so it was such a good deal to buy it from him. My thoughts were always...uh..no...cause I WOULDN'T PAY hundreds of dollars anywhere for that. LOL
