I assume that this is the only return filter going to your furnance which would be located in the attic. Check all other bedrooms and see if there are 2 grill openings in the ceiling (meaning that room has its own supply register and return register) or if there is only 1 grill register in each bedroom.If only 1 grill register in every room than this is your only return grill intake for the furnance.this filter should be checked every 30-45 days and replaced if dirty.Keeping this filter clean will keep your furnance running at its peak performance. If however there are 2 grill openings in your bedrooms then you will have to go into the attic and check the filter inside your furnance also.I assume your home is single level with one heat system?

The four items that you need are the Chalice (attic), the Lantern (bedroom clocks), the Ice (refrigerator), and the Draught ("poison" bottle in basement). You will also acquire a key to the cellar and a pick ax from the hallway knight. You lose these at the end, but they are not items. You also use the flying broom to reach the attic, and the kerosene to fill the lantern.(see the related question)
To blow in insulation in an attic, you will need a machine specifically designed for this purpose, which can usually be rented from hardware or home improvement stores.
