What impresses me about the Frantz Filter system is the low-tech, cheap and effective principle and that they have been in business for decades with the same product.
Turns out TP filter efficiency is even higher than I remembered.
From the Frantz FAQ page:
It has the ability to remove any Solid Particle down to 1/10 of a micron (.000039")and up to 6 ounces of Water.
I bet there are tests/filter shoot-outs online, proving and disproving claims.
Only personal long-term use will show what works best.
Just good to see the primitive Frantz system on the market unchanged for decades.
