I finally measured my filter!
It was quite difficult to remove it without damaging it. In the niche was small foliage, probably from a whole tree. The filter was quite dirty. I vacuumed the niche and the filter as I don't have a replacement and was planning on putting it back in as soon as I measured it. Its dimensions in centimeters are 26.5x19x2. That is, it is identical to the cheaper 27277en000 filter, as well as to other analogues with a similar size. My filter is 27277jm01a, according to the Nissan catalog. (By the way, on the site
https://www.nissanpartsdeal.com/ the size of my original filter is indicated with a large error, for example, the thickness is 4cm, but this size will not physically penetrate the installation hole. This data confused me and because of this I set to investigation)
I could not find an analogue for him - a replacement. For what reasons my filter, which is recommended by the manufacturer, has such a cost, I do not know. I can safely assume that the matter is in the properties of the filter material. It looks like coal. I thank everyone who responded, thanks guys!
