Change the filter! Don’t waste your money on the cheap horsehair filters that cost less than $2.00! Spend the extra money! $5.00 for a good pleated filter.
Fiberglass filters only catch large chunks of dirt in the air before the blower of the furnace pushes everything else back at you with the heat.
Typical filter sizes are 1, 2, 4 and 5 inches thick.
Depending on the thickness of the filter and if you have animals (i.e. dog or cat) determines how many times a year you should be changing the filter.

1in filter – monthly
2in filter – every 1-2 months
4in filter every 3-4 months
5in filter every 4-6 months
