About Filtrexx

The Filtrexx Brand

Grounded in Science. Filled with Possibilities.

In 2022, the acquisition of Filtrexx by MKB Company created a powerful force in the erosion & sediment control and stormwater management industries. Now united as one industry leader, we are dedicated to manufacturing groundbreaking products and solutions that cater to contractors and distributors who prioritize environmental excellence.

For years, both MKB and Filtrexx have been individually pioneering innovative products and services, as well as educating the industry on the most effective and reliable stormwater BMPs available. By merging our expertise and bringing together our product lines, we are proud to present the finest erosion and stormwater control offerings to the entire industry nationwide.

Under the Filtrexx brand, you can now find all tubular/filter sock products manufactured by MKB Company. MKB upholds the Filtrexx legacy of being a leader in research-driven product development. You can trust Filtrexx Advanced Tubular Products to be high-performance, research-backed, reliable, and cost-effective. We continue to innovate BMPs for both construction and post-construction applications by developing advanced netting and fill material options.

You’ll continue to see our signature Green® color in our SiltSoxx product line, representing a sustainable product, trusted by customers and regulators, that saves you money.

While we have refreshed the Filtrexx brand, maintaining our recognizable ‘r’ icon pays homage to its legacy. The transition to an uppercase, bold font signifies the official integration of Filtrexx into the MKB family – making us bigger, stronger, and bolder together.

MKB Company stands committed to preserving the legacy of the Filtrexx brand, ensuring your trust remains intact as we unite as one.
