Better how? Easier to clean out or better at collecting dust? The Winn filter is the one best mod to increase catching the fine dust and keeping it out of the air. A cyclone separator makes it easier to collect and dump out the larger chips and dust. But the cyclone actually reduces the overall suction of the collector possibly reducing what s collected at the tool. The HF doesn t have a whole lot of power to start with. I put both the Winn filter and cyclone on my HF and it does ok for my use. The cyclone just makes it easier to empty without having to remove the plastic bag.

Just ad a note…since the Wynn filter has significantly more surface area, it reduces the back pressure on the fan and air flow increases. This can actually be a problem by over amping the motor. Best to install a blast gate and keep it pinched back some. Adding a thine type separator also increases back pressure, so it more than likely offsets the filter change, plus some.

My can lid helps too, but I still have to pinch back a blast gate to avoid tripping the motor at startup.
