These are the Nissan-Supplied instructions for the
In-Cabin Microfilter. They are somewhat generic, and were not
100% accurate to my car. The only difference was that my car
did not have the "Glove Box Finisher". Besides that,
everything else was correct. Perhaps the Glove Box Finisher
was eliminated in later 5th-Gen Maximas?
I bought my filter at a Nissan Dealership. The
cost for one of these babies is $58.74!!! Cheaper deals can
probably be had on the Internet.
changing this filter approximately once per year. This
procedure is not listed in the owner's manual, as Nissan prefers
this operation be dealer-installed. With only a Philips
screwdriver, if you are the least bit competent you can do this job
yourself and save the money. The filter alone is expensive
||Start by removing the glove box latch.
2 screws and it's out.
||Next, remove the 4 screws holding the
glove box in place. There are 2 at the top and 2 at the
bottom. You will have to disconnect the glove box light, and
the air bag connector. Both come off easily, and the entire
glove box can be removed.
||Once the glove box is out, the next
step is to pop off the metal clip holding the white filter cover in
||Now the filter can be slid out.
Apparently, the microfilter put in at the factory is a single piece,
and does not look like the factory replacement filters you will put
back in. In fact, the replacement filters look much nicer
(higher quality). This picture shows the empty hole where the
old filter was.
||This side-by-side shows the stock
filter removed on the left, and the replacement filters on the
right. I was quite amazed at how dirty this filter got.
The replacement filters come in two pieces, and have plastic holders
that enable them to slide into place more easily than the original
My filter had all sorts of black dirt, crud and leaf
pieces in it!!! And I keep this car garaged, and never drive
it in the rain (if I can help it).
||The easiest way to get the new filters
in is to put one in at the bottom, then once it is in, slide it up
into the top position, since it is difficult to get the proper angle
to put the top one in directly.
||Here is the completed filter
installation, with both filters securely in place. Replace the
white filter cover, glove box, reconnect the light and air bag connectors, and this
installation is complete. Ahhhh, fresh air to breathe once
