I am in the process of designing the enclosure for a small kiosk like project, and intend on having two fans (Noctua NF-A12x25, chosen for their high runtime rating, quietness, as well as other factors). I want to filter the air to prevent dust accumulation over many years of operation, and have tried searching for a way to choose a filter, but I am too inexperienced in this topic and cant seem to find the right keywords.
What I want to know is, given a filter that filters smaller particles, and thus causes more resistance to the air, can "two" of them be placed in "parallel" to increase airflow? is there a limiting factor, or can we possibly use a small fan with a very large strong filter?
My apologies if my question is too basic or if my tags are wrong
