Looking for Filter Material Ideas for Air Cleaner

[markinnaples]

Freddie, I have the VS on my car, though I'm not sure if they're the same as Bentley's, mine have two metal screens at the top of the VS and the filter material goes between the two circular metal screens. The VS diameter is smaller and the lower screen sits on a ridge with the filter material on top and the top metal screen goes on top of the filter material with a round spring that expands into a flange at the top of the VS. Terrible explanation, sorry, but that's how mine work.
