Great cabin air filter, very easy to install

Size: 1-Pack

.“Great, affordable cabin air filter that fit my 2024 Toyota Corolla Hybrid perfectly. My Toyota dealership wanted $60 to replace it, but I was able to install this one myself in under 15 minutes. Easy, cheap, and works exactly as it should.”

Clean 2016 Prius

Size: 1-Pack

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.
