Good PC case fans are incredibly quiet, move a lot of air and last forever. That's the nice thing about having some many companies competing over optimizing them for so long. I have a similar setup, just premade from CleanAirKits. Allergies are gone, house has far less dust and cat hair floating around. Can't do anything for wood smoke though, that would need carbon filters - which run out quite quickly.
