Review on AUSANAT Mini Portable Air Purifier: Car, Travel, Baby Stroller, Home- Office Use, USB Rechargeable, H13 True HEPA Filter by Scott Adaymiln

Everything is good, but not worth the money. Lowering windows is more efficient. The fan is pretty weak on the highest settings and doesn't pull smoke very well from 1 inch away. So I can only imagine that this job will take several days to filter out some of your car air. It did not reduce odors and made no difference when smoking. It's noisy! Almost as loud as my bedroom air purifier. If your car is musty or smoky, leave a bag of charcoal on the dashboard when parking.
