Remove the glove box door (six screws). Remove the metal spring clip that hold the two filters into the air duck directly behind the glove box. There are two filters, one above the other. Pull the lower filter out first by pulling it directly toward you. The top filter will slide downward to the bottom of the slot. Pull it out also. Replace with two new filters, but putting one into the slot and pushing it upward to the top of the slot. Then while holding the top filter in place, push the lower filter into position. The lower filter holds the top filter up in place. Replace the metal spring clip on the lower filter.

I doubt that a 1993 model has a cabin filter. Go to a parts store and ask for one. If it has one they will sell it to you. Purolator cabin filters come with instructions.
The cabin air filter is located behind the glove compartment, you will have to unscrew 7 screws to remove it and to get access to the Cabin Micro-filters door. Nissan recommends to replace the micro-filters every year or every 15,000 miles.
The 1999 Nissan Maxima does not have a cabin air filter. It never came with one.
