poly fiber

  • We are currently upgrading MFK. thanks! -neo
It's more expensive than walmarts poly-fil :nilly:.

But it is thinner, stiffer and easier to work with in some circumstances (HOBs).

It works well too.

There's a filter for air registers (vents) that is a little more course and about 4" wide x 10-12" long that works also.
