Fit my 2016 Prius good. I have had it installed for 10,000 miles and seems to work good still. With a nasty truck or old oil burner around me (windows up) I can smell some fumes but not much. Fumes might be coming from other sources like Worn window seals or firewall wire passages. If I flip the switch to recirculated air, I don't smell much. Great for the price and will buy another when I need it. Filter was great for winter driving. Better protection than stock. I forgot there was dog smell in the car.

Good air filter

Size: 1-Pack, Size: 1-Pack

This cabin air filter looks well made and fits perfectly. Installation is very easy, and once installed you can notice cleaner airflow inside the vehicle. For the price, it offers solid performance and is a great alternative to the OEM filter. The only reason I’m giving it 4 stars instead of 5 is that the material feels slightly thinner than the original filter, so it may need to be replaced a bit more often. That said, it still filters well and works as expected.

Great replacement cabin air filters

Size: 2-Pack

This cabin air filter was a perfect fit for my 2019 Camry XLE. Great price, too. I just took the old one out and popped the new one in, took about 2 minutes or less. Seems to be great quality.
