Our Economical 3-Stage filters has the same specs as our Heavy-Duty Gold filter but instead of a rigid metal frame, it has a hand-sewn fabric frame.  This allows the filter to bend and flex and fit in areas where a metal filter can't go.  Doing away with the metal frame also allows us to reduce the thickness of the filter to about 5/8 inch.  Just keep in mind that these flex filters are best used in special applications.  If possible, we recommend our metal framed filters where possible as they hold up better over the years.

This filter comes in 5/8 inch thickness only.
