The Shop Fox W1746 Fine Air Filter features a 0.3 micron filter to clean the air of smaller particles that many woodworking dust collection and air filtration systems might miss. The air cleaner has 3 fan settings (100, 140 and 200 CFM), 4 fan-off delay settings, an automatic shut-off and a rather small footprint.
At $100-$150 the Shop Fox W1746 is reasonably modestly, and replacement filters are about $11 each.
I’ve been on the lookout for a decent compact air cleaner setup, and the Shop Fox looked to fit the bill. The unit I ordered from Amazon should be arriving in a few days, so a review is imminent.
