U.S. automakers are following the example of their foreign counterparts by offering help for the millions of Americans with allergy problems.
But, in many cases, the extra equipment means a higher tab, the Wall Street Journal says.
While car makers abroad have long focused on making their vehicles allergy friendly, U.S. auto makers traditionally have not. But now, the filter systems and other allergy-fighting features are becoming more common here.
Most manufacturers are attaching basic dust and pollen filters to cars' heating and air-conditioning systems to catch particles before they enter the cabin.
Some cars have more advanced filters -- carbon, ultraviolet light or electrically charged -- to catch certain gases and odors. While some manufacturers offer filters standard, many make them part of options packages.
The purifier on the Lexus LS 430, for instance, is available as part of an $11,320 "ultra luxury selection."
