Central heating system with no spot for filter?


My friend lives in a house with central heat/AC. I could be wrong, but where the return duct comes back into the main unit, shouldn't there be a spot for a filter? In this case, there is not a spot; it is just taped shut.

Could this be normal, or no? I've never seen a central air/heat unit without a main filter, and I can't imagine all the dust/dirt/debris/etc. that the blower motor and other components are collecting. Could the filter(s) be located at each return vent in the house (those vents are only 6"x9")? If so, I'd assume that there should still be a filter at the main unit.

trace back from the unit all the returns have to hit the main return someplace...filter might be there.if not remove the supply fan access panel and where the return comes into the unit slide one in there for now...no big return grill somewhere around the stat area as usual

Just checked in the basement...no signs of filters anywhere along the return ducts. Any other suggestions anyone?

Hmmm, where on the return duct? Right near where it enters into the main unit?

It should be right at the unit, or can be inside once you remove the blower access door.

Here are a couple pics. This first pic shows the return on the right coming in to the furnace on the left. It's foil-taped shut (no spot for a filter):



In this second picture, I removed the access panel on the back of the furnace unit. Still, nothing where the return duct (left) comes into the furnace (right):

If there is not a spot at the furnace, or inside the furnace at the blower area, probably was one placed into the returns, if they are large enough to hold one either flat inside, or at a angle inside the opening.

It does look like there should be a filter channel in the return duct near thr furnace, however, as is the case with my furnace, there may be an access door to the circulating fan where there is a filter rack on top..they do exist in some furnaces including mine.
