ABSTRACT OF THE DISCLOSURE An air intake system for a residential combustion furnace is disclosed. The air intake system comprises a membrane formed from an amorphous polymer of perfluoro-2,2-dimethyl-1,3-dioxole, the membrane exhibiting an oxygen/nitrogen selectivity of at least 1.4:1. The permeate section of the membrane is adapted to be in fluid flow communication with a combustion zone of the residential combustion furnace. The membrane preferably has an oxygen flux in excess of 100 Barrers, especially in excess of 500 Barrers. The air intake system provides oxygen-enriched air for the furnace, to make the furnace more efficient.
