i've read that there is a pretty quality (and results) huge gap in low end to high end, particularly around the quality of materials and forethought of installation layout, etc
I'm sure, for that scenario I wouldn't choose to go that route again, but for a whole house I could see it making sense if you can figure out a way of getting the installation right.
My wife is also really struggling with with her dust mite allergy and with the right filters etc this is supposed to be very good for that which is an other bonus
