YOUR FURNACE’S FILTER -
WHAT IT DOES
The filter in your furnace takes the lint and dust out of the air that passes through it. This keeps dirt particles from getting into the moving parts of the furnace, where they could cause serious damage. It also keeps the dirt from circulating through your home.
As the filter continues to collect these particles, it becomes clogged and no longer allows enough air to circulate through the furnace. If this happens, the heat exchangers and blower motor could overheat; a potentially dangerous situation. It is very important to keep the air filter clean! Never operate your fur- nace without a suitable air filter.
WARNING: When replacing fil- ters DO NOT use a type with excessively high pressure drop. Some high efficiency filters avail- able will cause the furnace to operate improperly and could re- sult in a safety hazard.
