The Strainrite Companies introduced the Hi-Pro Micro line of high-performance filter bags several years ago and it has proved to be a very successful product. This line provides a full range of absolute rated filter bags to meet all your exacting needs. All four editions of the Hi-Pro Micro (HPM) line incorporate Strainrite’s unique graduated layering of media — starting with a built-in pre-filter inner layer and progressing to the tighter outer layers. The smaller particles are systematically removed as fluid travels through multiple layers with each individual layer performing a special function. This graduation aids in the prevention of premature blinding which causes unnecessary filter change out.

The product line offerings include the Hi-Pro Micro 9200, the Hi-Pro Micro 9500, the Hi-Pro Micro 9700, and the ultimate in bag filtration, the Hi-Pro Micro 9900. An unrivaled product, Strainrite’s Hi-Pro Micro line is the product suggested by the U.S. Environmental Protection Agency for the most effective removal of giardia and other cysts. Strainrite’s product has the lowest standard deviation of any other filter, which means users achieve more consistent results from batch to batch. Equally important, this product presents the ultimate value in high purity filtration.
