Abstract
Abstract In a mist filter for use in eliminating moisture from the humidity laden air traversing through the evaporator of an automobile or other air conditioner, the filter comprises a pair of corrugated screens, with the corrugation of each screen being arranged perpendicularly with the corrugations of the other adjacent screen, a pair of said screens being fastened together, and arranged contiguously with the evaporator of the air conditioner.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
176 words
A combination of an automobile air conditioner including an evaporator and a filter for removing water from the moisture laden air passing through said evaporator, said filter maintained in thermal conductive contact with said evaporator upon its air downstream side thereof, said filter having a first layer of screen material, said screen material being corrugated, a second layer of screen material, said second layer of screen material also being corrugated and with the corrugations of the second layer of screen material being arranged contiguous with and perpendicular with respect to the corrugations of the first layer of screen material, fastener means holding said first and second layers of screen material in contiguity, said filter incorporating the juxtaposed corrugated layes of screen material and through the temperature differential between the chilled surface of the said evaporator and the warmer surface of the screen filter causing moisture to adhere particularly through capillary attraction on the said filter thereby effectively eliminating a substantial percent of the moisture from the moisture laden air passing through said evaporator and said filter.
Claim 2
Dependent Claim
176 words
A combination of an automobile air conditioner including an evaporator and a filter for removing water from the moisture laden air passing through said evaporator, said filter maintained in thermal conductive contact with said evaporator upon its air downstream side thereof, said filter having a first layer of screen material, said screen material being corrugated, a second layer of screen material, said second layer of screen material also being corrugated and with the corrugations of the second layer of screen material being arranged contiguous with and perpendicular with respect to the corrugations of the first layer of screen material, fastener means holding said first and second layers of screen material in contiguity, said filter incorporating the juxtaposed corrugated layes of screen material and through the temperature differential between the chilled surface of the said evaporator and the warmer surface of the screen filter causing moisture to adhere particularly through capillary attraction on the said filter thereby effectively eliminating a substantial percent of the moisture from the moisture laden air passing through said evaporator and said filter.
