Air line filter for air bearing arm


Hello Audiogoners. Does anybody know what to use and where to get a filter to put in line right after the air pump? Thanks.

When I had a Maplenoll TT, I used to get inline air filters at my local aquarium store.
Thanks to all. I received an e-mail from ET to use automotive clear plastic fuel filters, $5 max. Already installed and works great. Go figure!
What affect does this inline filter have on airstream delivery?

I assume this filters the air of particles to keep the air bearing clean?

Do you install this close to the pump or closer to the turntable?
