This is a standard single stage gas furnace that can be mounted in several positions. If this unit was installed correctly, yes, there should be an air filter somewhere in the system. locate the blower compartment, it will be the smaller of the two doors on the front of the unit. In the ductwork that attaches to that end of the furnace there should be a slot or a long skinny cover plate, there should be a filter in the slot or behind the cover. If you cannot find one call a dealer or qualified service person to come out and go over the system with you. If it is a new system, I would call the installing dealer or if you would rather, get a referral from a friend. Don't be bashful and don't feel dumb, if you don't know about your system, ask. Stupid is forever, ignorance can be fixed. It is the time of year for a fall routine service anyway so while they are there ask them to explain how your system works and what things you can do like filters and condensate drains and the like. If they talk down to you or seem disrespectful, don't ever call them again. Look for technicians who are NATE or PHCC certified. They may cost more but they know what they are doing.

sounds like you have dirt in your fuel tank, as the heater runas it picks up the dirt in the filter plugging it up. When the heater shuts off, the dirt falls out of the filter. You start the heater back up and it does it all over again. Empty your tank and change the fuel filter. Should be fine then.

Motor keeps running and filtering nonstop

Check your temp probe, if it is overheating it thinks it needs to run the heater and the pump.

My Aloha (Airtech) electric ceramic heater 02044 does not work on high. Could it be that the filter needs to be changed and if so, where can I buy the filter-that size does not seem to be readily...

Take the entire unit outside and blow it out with compressed air.
1) The filter is likely dirty and obstructing airflow. Be sure to clean per the user manual.
2) The unit is probably full of dust and needs to be cleaned periodically.

How do I replace the HEPA cabin filtert on my 2005 Nissan Maxima?

I'm not certain about the 95 model but a lot of them are behind the glove compartment door. You will need to actually remove the glov compartment door to get to the in cabin filter. I'm not sure if this helps any. good luck.
