Works great for 2013 Toyota RAV4
Fit my 2013 Toyota RAV4 perfectly. Easy to install. Well made full HEPA filter with carbon layer. As good as the expensive filters I use in my home. Have not had chance to see how well it works during spring allergy season yet, but I expect that it will do great.

Best cabin filter I've ever used...
After my girlfriend dumped a container of Italian beef juice onto the passenger side floor mat and having it soak into the floor mat and the carpeting, it left my new car stinking of Beef gravy. I bought this to hopefully extract the annoying and horrible smell from my car. The filter is perfectly made and fit with exacting precision and minimal effort. If is well built and of superb quality, materials. The bright white cartridge style top side is pleated for maximum air to filter contact. The other side has these wonderful beads of activated charcoal/carbon that are for absorbing odors. As soon as I installed it and turned on my ventilation/ AC/Heat, I could smell the clean filter and also a sense of cleaner air. Hoping this will do the job in time!!

Good Fit & Fresh Air, But Slightly Reduced Airflow
I recently installed this cabin air filter in my 2024 4Runner, and it fits perfectly. It does a great job of filtering out the dusty Las Vegas air, leaving the cabin smelling fresh. However, I did notice a slight reduction in Airflow, on the highest blower setting, it feels like the output is about 25% lower than usual. It’s still early to tell how it will perform long term, but so far, it's doing its job well. If you prioritize air quality over maximum airflow, this is a solid choice at a good price too!

Filter fits well into cabin filter compartment of 2011 Toyota Avalon Limited.
Fits easily into my cabin filter slot of my 2011 Toyota Avalon Limited. It has performed well after a month of use. The design of this filter appears to be superior to the filters that are utilized at the Toyota dealer. The filter was easy to install via the back of the glove compartment.
