Everybody claims to have the best. Yes some are good others are no better than filtering through a dirty old sock. The only way to get to the trueth is review the results from an independant labs tests. Look for the micron's that it filters down to. You will be shocked as one of the least advertised as being the best is one of the best and there price is no higher than most. I can't give you names as I would end up on the inside looking out.
