I tried the cheap IKEA model and with my severe dust mite allergies the model was insufficient in comparison to calm my sixth sinus-bound sense.

My main suspicion: In my last 3 abodes with pre-1955 construction in East Coast, the pre-filter on the top Wirecutter pick needs to be cleaned 3x per carbon filter replacement in order to reduce largest particle accumulation on the carbon or HEPA filters.

The inexpensive IKEA model did not have a viable and easily cleaned pre filter as far as I could figure out.
