I'm pretty sure you mean poly filters.
Poly Filters are great to have on hand. They come in sheets ( pads ) that you place in an area of high water flow. They remove a lot of different undesirerable chemical compounds in your tank water.
Here's a link that may help.
Check it out, and click on the Poly Bio Marine, Inc. link on that site too - it'll take you to the manufacturers site as well.
See ya later -
