The CleanSpace CST1004 and CST1005 filters are both designed for use with CleanSpace PRO and ULTRA powered air purifying respirators (PAPRs). While they share similarities in filtration efficiency and compatibility, they differ in capacity, size, and suitability for various work environments. Only the CST1004 High Capacity Filter is NIOSH approved and, therefore, available in the US - the CST1005 Standard Filter is not Niosh approved and, as such, is not made available to US customers.
