My experience is that, while an air cleaner is a great supplement for collecting dust, especially if it has a HEPA filter, the air cleaner alone is not generally enough. My guess would be that, without a HEPA dust collector (cyclone or not) sucking the dust through a hood mounted on the lathe (or near on a stand), any air cleaner would need constant maintenance to keep the filter clean. I have a cyclone connected to a hood on my lathe and, based on observation, I can see that vast majority of finer dust sucked into the hood. If all that dust was filtered through an air cleaner, the filter in that air cleaner would be full in a very short time. My air cleaners need maintenance, but my cyclone takes most of the chips and dust right at the source. In the end, I have always believed that air cleaners are a great add-on to a dust collection, but not the solution in and of themselves. So, particular air cleaner seems like a good one but it's no better than other air cleaners if it's the only dust collection method used.
