This is a pre-filter/waterproof filter I had needswings to custom make for me for my needswings cai filter. I bought a larger filter so no longer need this.

It is a pre-filter that you can take off and rinse and lets you go longer in between filter washings.

It is also waterproof so it does not allow the filter to absorb water for safety.

$15 shipped.
