I’m not familiar with that unit, but the specs look like it’s more suited for filtering viruses and bacteria. If dust is the only problem, you would be spending a lot of money on expensive filters unnecessarily. Often these filtration units come with two or more filters in series, or a filter with a carbon filter attached, which provides more flexibility and economy with replacing or vacuuming the first stage filter.
Note that virtually all the filtration units will be loud at the highest setting, so I suggest to get a unit that has several (manual) speeds to choose from. This unit only has auto, high and sleep speeds. When I went shopping several months ago, I eventually decided on the Winix PlasmaWave 5300-2. I’m happy with it overall, but 3rd speed seems to be <1/3 of the 4th speed, and I would prefer to have the speeds spread out more evenly.
