My experience is that the Wynn s are worth the money, and their customer service is excellent. The real issue is whether the effective CFM draw from the HF Dust Collector is sufficient. The 0.5/0.3 micron filters require a lot more umph than a 5 or 1 micron bag or canister. The effectiveness of a DC system is more than just stated horsepower and stated CFM.

Actually, since there is so much more surface area for the air to exit, despite being a finer fabric, the canister filters provide less resistance to airflow than the bags. It is often necessary to throttle the inlet of the fan to keep it from overamping due to reduced resistance. That was true if my HF unit with Wynn filter. I eventually added the woodcraft trashcan chip separator and that provided enough pressure drop to stop from popping the breaker, and I no longer have to pinch back the blast gate.
