We’ve been using one, and they’re great. Might try to make the double filter version this year.

I’ve personally used both the flat single-filter version AND the triangular two-filter version, and based on subjective personal experience I would argue that the benefits from the second filter, both in terms of airflow and filtration, are absolutely worth it. If you need a makeshift air filter and you have two filters to work with, build the triangle (if not the box, i have no idea how good that one works but based on the info here i presume it’s a fair bit better.)

This trick works. We use it in my house.
