I wonder if the main benefit is from switching to a airflow optimized fan that has suddenly been put into a static pressure system (the lasko) to fans that are designed for significant pressure (the arctic fans).

It’s a reasonable idea, but the filter cube is based on ease, basically only has 2 parts (plus tape, so 3), and you can get at of them at your local Meijer or lowes, no special order, no wiring. This adds complexity and cost for a nicer experience. At some point it makes sense to just buy yourself a coway
