There’s smaller filters of the same (or better!) quality made for different types of air-purifying devices. If headroom is a problem, I wonder if you could use a smaller, more powerful fan and make a longer tunnel type of box to get the same (or better!) CFM of air filtering.
elevating them is an attractive option
I’m not sure attractive is the right word there! (I’m just kidding, I know what you mean.)
I will note that, at least in the fans-for-computers-and-electronics industry you can pay more money and get the same CFM in a smaller AND quieter size. Motor type/quality and blade design has some sort of effect on this. Diminishing returns and all that of course.
I don’t know if this really applies to the types of fans a person would be using for something like this.

The main downside of small powerful fans is they tend to be quite loud.
Yeah, definitely.
