Effective January 1, 2023, Delta Pure Filtration operations fully merged with AJR Filtration. Delta Pure string wound, melt blown, and carbon wrapped filter cartridges are now part of AJR Filtration's expanded portfolio, with the excellent customer service, ordering flexibility, competitive prices, and fast lead times our customers depend on. Beware of impostor sites branded as Delta Pure offering copycat products. Only AJR Filtration manufactures the former Delta Pure Reliable Filtration products.
