How often should a HEPA filter be replaced?

[Chiks]

Last year, I started wondering how often the HEPA filter in my car should be replaced. I checked the manual and a few online resources, but I couldn’t find a clear answer. Some people said it should be swapped out annually, but there wasn’t anything official. If anyone has experience or knows the ideal schedule, I’d love to know!

I change mine once a year. But in the manual, it says every 2 years, or every year in cases of off-road/dirt road driving.

Thanks for the clarification. Since the manual suggests every two years for regular use and annually for off-road driving, I think I'll stick with changing mine once a year for better air quality

Yeah, that's right! I have noticed that a clean filter helps the HVAC system to run more efficiently.

yeah a clean HEPA filter can really improve air quality and keep the system running smoothly.
