Their web site has no technical info at all. Like what is it made of and how and why it works...basic stuff like that.

Their magazine adds have some comparisons to other brands (brands "A" and "K"), but that's all I can find.

They say it filters better than cotton gause filters (K&N)....I don't have any trouble believing that one....my personal experiences wtih K&N have been terrible! Notice that they aren't comparing it to a UNI or any other foam filter.

 

Reconranger, I "think" these are going to be like the filter on my Deere. It is like a micro fiber. It looks and feels like a felt material. "If"it is like the filter on my Deere I can tell you they REALLY filter!!!! Mine is a two stage and the second stage looks brand new when the 1st stage is covered in fine flour dust. I have no idea how good it is for flow??? Just a guess, it looks as good as a foam filter.
To get the flow up you need a lot of surface area. That is hard to do in a small quad. The filter on my Deere is about 8" X 16". It's a big boy!!!

 

I remember the old KTM dirt bike filters were just a soft foam type material and they required no oil...... they were almost like one of those "memory foam" pillows in their feel...maybe they are something similar to that....
