Great shortlist, and requiring baffle filters plus a true 24-inch depth really narrows the field, so you have clearly done your homework. Since you already owned a Zephyr for seven years and liked it, that reliability history counts for a lot. One tip: compare the sone ratings at similar CFM settings for both models, since noise at high speed is the thing people notice most after installation. Also double-check the duct size each unit requires so your existing ductwork does not need rework. Good luck with the decision, you will appreciate those baffles over mesh either way!
