If it's your first time removing the filter, yes it's a pretty snug fit. The plastic tabs that hold it in place are slightly over-sized so it takes a good pull to get the filter unit out. It can be a little disconcerting at first.
Once you get it out you will see that filter unit has tabs for disassembling. This allows easy access to the gray foam filter (which can look clean but is usually loaded with a fine dust) which should be vacuumed clean. Underneath the foam filter is the electro-static filter which is white and pristine but should be vacuumed too. When vacuuming the foam filter be careful not to accidentally suck it into the vacuum cleaner. To get around this some people rinse the foam filter in water to remove the dust then blot it dry with a paper towel to remove all moisture. Reassemble the filter unit and replace in projector.
Some people like to use compressed air to blow out the dust. However this should be done outside so as not to introduce the dust back into the room air.
For the overly cautious if the filter is going to be out of the projector for a long time drape a sheet of microfiber lint free cloth across the opening. Also turn off the furnace/air conditioner while cleaning the filter to minimize the movement of air in the room.
