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!!
