Piston engine aircraft with multiple air filters and electronic switching that would allow pilots to switch to a clean filter when one became clogged. The filters could be situated where aircrews could change them out when they became clogged allowing a clean filter to always be online. Of course waiting until those old constellations were built again might take a few years:). That was a great passenger plane, BTW. Far more comfortable to fly in than todays crowded jets.
