The heritage of The Strainrite Companies is closely tied to the initial development of filter bag technology. Their founder, John H. LaPoint Jr., was an integral part of the team that conceived, perfected, and offered the original filter bag. 


The Strainrite Companies strives to apply the filtration expertise they have gained in over 37 years of filter manufacturing. They offer a complete line of filter bags, cartridges and housings.
