The single most often cause of shortenrd equipment life is poor air filtering, either too restrictive or allowing unfiltered air to pass.
The filter is not there to clean the air in your house, it is there to protect you equipment. There is nothing better or cheaper than throw away Fiberglas filters in a good sealed mount, and changed regularly.
Are you kidding me? Filtration is not designed only to protect equipment. It's designed to remove particulate from the air occupants breathe as well.
