All the commercial units using dedicated media are going to do as good a job as their fan and filter efficiency allow for from a CADR perspective - but all of them are going to be simply be too expensive to run from a filter cost perspective in a high contamination environment like during construction work inside a home.
Here is an update on what a merv 13 filter looks like after 2 weeks in a windows and doors open remodeling environment POST any sawing or heavy demolition all the really dirty stuff has been completed, so this is just from moving materials around and walking around on top of what floats in through the windows and screen doors.
The unit runs 24x7 on low.
As you can see its grabbing a substantive amount of crud.
