This is the most complex and over-engineered cabin air filter I have ever seen, and I mean that in a good way! The overall shell is a hard plastic, and inside it are two basic parts; the filter (HEPA quality) and the loose fill activated charcoal. The filter media appears to be operating room quality, and if I were to guess, I would say it's like a MERV 14 or greater. The pleats are plentiful, and the spacing of the pleats are perfect, as well as the attachment of the media to the filter frame. The charcoal is a loose style fill, and it fits between the back of the filter media and the filter screen on the very back. This must have 5 times the amount of charcoal compared to the charcoal infused media you can get from many suppliers. The frame fits perfect in my 4runner, and it is hard plastic with good gasket material to further help the effectiveness of the media. All in all, this is an incredibly engineered filter, and if you're the type that wants nothing but the best for your vehicle, you've come to the right place by choosing this one. It is pricey, at $20 for one filter at the time of writing this review, but this is a textbook case of "you get what you pay for." I am going to start only buying these from now on, as they are the best quality and construction filter I have seen, and I highly recommend this filter!
