I was looking through some old Popular Mechanics mags from the 1950s that I found, and saw an ad for a filter called the "Lifetime Filter". It was a cone shaped thing made of sintered bronze that fit in the external filter housing on these old car engines. It's claim to fame was that aircraft engines (piston? jet?) used them filtered down to a small micron and could be cleaned and reused. And they didn't absorb the additives.
Were they any good?
Today I found a stainless steel element filter with the same claims (Purepower).
I am intrigued because I like to reduce waste and if it filters better, great.
Anyone know about them or used them? Any good?
Thanks.
