One and only purpose of a furnace filter is to protect the furnace from damage caused by dust, lint, or foreign objects that find a way into the air stream.
Without filtering, these particles may cause damage to the furnace or, at a minimum, reduce the overall furnace efficiency; which will cost you more in energy.
A lot of air carrying dust particles moves through your furnace. As dust and deposits accumulate, your furnace has to work harder and harder to draw air through the filter.
A black furnace filter is a red flag that something could be seriously wrong with your heating system. While it may be that you haven’t changed the filter in a really long time, it could be a sign of more serious problems including:
• Inadequate combustion air
• Carbon Monoxide
Inadequate air supply or carbon monoxide can both cause soot to form on the filter. And, mould in your home can be a serious health hazard.
Change your Furnace filter every three month to protect your equipment from unnecessary breakdown.
