Replacing the engine and cabin air filter regularly, I agree. But for the seat filter, only IF you use the seat AC all the time AND smoke inside the car or drive with windows/sunroof open. The M35/45 seat filter is the most over-priced filter I've ever seen for a car. Even at a discounted price of $55, it's still way too high.
For comparison, an 03Q and 06M have cabin filters of the same dimension, 8"x9",the only difference is that the Q has activated carbon filter ($60 at IoS) while for the M is a regular HEPA filter ($29 at IoS). The seat filter is less than 4"x4", yet priced close to the Q's cabin filter. And you need 2 of these. If you are resourceful enough, buy a 3M Filtrete (it's also HEPA), cut it into the required dimension, wrap it with a velcro or something similar and plug it in.
When Beshoff Infiniti-San Jose did the 60K Maintenance on our M, I specifically told them not the replace the seat filter ($159 savings). Although the filters are 3 years old, I inspected them with magnifying glasses and compared with the Q's filter - no dirt at all. With that money, you can buy 20 quarts of Nissan Matic-S from IoS, to flush your transmission. Well...I actually bough 24 quarts from Joe.
