i have seen in line water filters used to filter beer but my question is could i use one between my primary regulator and secondary regulator because it needs at least 30psi to function and i'd rather use it during the serve to save on work and so i dont move it round so much i also make that turbo vodka so would be great if i could use it for that too if anyone has experience using these? any good? can you wash the filters? do i need to change them every time i use them? can i use them as i serve the beer between regulators? by the way im using sanke kegs and professional setup from a pub thanks guys
