1. An advanced energy recovery ventilator comprising:
a) a composite ion exchange membrane comprising:
i) a porous polyolefin support layer having a thickness and comprising a plurality of pores that extend through the thickness;
ii) an exchange polymer coupled to the porous support layer;
iii) an intake side;
iv) an extract side that is opposite the intake side;
wherein the composite ion exchange membrane is non-permeable, having a Gurley Densometer reading of at least 500 seconds;
b) an intake air inlet for receiving intake air
c) an exhaust air outlet;
wherein intake air enters the intake air inlet, passes by the intake side of said composite ion exchange membrane and exits the exhaust air outlet of the energy recovery ventilator as exhaust air;
d) an extract air inlet for receiving extract air;
e) a supply air outlet;
wherein extract air enters the extract air inlet, passes by the extract side of said composite ion exchange membrane and exits the supply air outlet of the energy recovery ventilator as supply air; and
wherein the exchange polymer is a thin-film of said exchange polymer extending on at least one of the intake side and extract side of the composite ion exchange membrane, and
wherein the thin film of said exchange polymer has a thickness of no more than 5 microns, and
wherein the thin-film of said exchange polymer is non-permeable, having a Gurley Densometer reading of at least 500 seconds.
