Is there a fresh air intake filter for Chevy Cavalier?

No, the Chevy Cavalier does not have a separate, dedicated fresh air intake filter like some modern cars with cabin air filters. The air that enters the cabin comes through vents and isn't typically filtered in a separate, easily replaceable filter cartridge the way a modern car's cabin air filter is. Any filtration happens through the vents themselves and perhaps some coarse filtering within the HVAC system.
