Filtrexx International

What Filtrexx International does

Filtrexx International is a private manufacturer of compost-based sediment control, stormwater management, and pollutant removal products, headquartered in Akron, Ohio. Founded in 2001, the company invented the compost filter sock — a three-dimensional tubular mesh device filled with proprietary FilterMedia — and built a portfolio of branded products around that platform. Core product lines include SiltSoxx (sediment control for perimeters, inlets, ditches, and slopes, with biodegradable Natural 'Plus' and rugged 'Extreme' variants), EnviroSoxx (stormwater pollutant filter with a new Industrial Blend formula targeting dissolved metals and nutrients), GreenLoxx (vegetated wall, slope, and shoreline stabilization up to 90°), GroSoxx (rain garden and bioretention), StormExx (channel protection), and supporting items such as Blower Truck Mesh and Traffic Marker.

The company monetizes primarily through one-time product sales of these BMPs, supplemented by project-specific consulting and technical support. Distribution is direct via the Filtrexx website (telephone 888.578.0777) and field sales, targeting specifying engineers (civil, landscape), contractors, and DOT buyers. Pricing is not publicly listed; customers request custom quotes, often anchored on multi-year construction project cycles. Marketing is content-led, including a free Design Manual with CAD files for 25+ applications, PDH-credit webinars, Lunch & Learn sessions, and a published research library. Filtrexx holds nine US patents and multiple registered trademarks, and its products meet or exceed US EPA, AASHTO, US Army Corps of Engineers, and USDA NRCS specifications.

In August 2022, Filtrexx was acquired by MKB Company, LLC, a stormwater innovation platform, and now operates as a subsidiary brand within the MKB portfolio. The company is described as a global leader in research and development of sustainable compost-based SMPs for stormwater, sediment and erosion control, pollutant removal, and living wall applications. The company was previously active in M&A, having acquired Weaver Express in November 2014 to extend its distribution and field installation capability.

Direct peers

• ERTEC Environmental Systems: ERTEC manufactures compost filter logs and fiber rolls for sediment and erosion control — direct head-to-head competition with Filtrexx SiltSoxx in the tubular compost BMP category used by the same construction and DOT end-customers.
• Aero-Flo Industries: Aero-Flo produces compost filter socks and complementary sediment control BMPs, competing directly with Filtrexx across construction-site perimeter, inlet protection, and slope interruption applications.
• GeoHay / GeoHayUSA: GeoHay manufactures agricultural fiber and compost filter socks for sediment control, directly competing with Filtrexx SiltSoxx in the compost-filled mesh tube category.
• Soil-Tek (Compost Logix): Soil-Tek (operating as Compost Logix) produces compost filter socks and organic BMPs, directly competing with Filtrexx across sediment control and stormwater filtration markets.

Broad incumbents

• Profile Products: Profile Products is a large-scale erosion control and vegetation establishment manufacturer (including North American Green blankets and Flexterra/Hydra offerings) that competes broadly with Filtrexx in BMPs but spans a wider portfolio across hydraulically-applied and rolled products.
• American Excelsior Company: American Excelsior manufactures erosion control blankets, turf reinforcement mats, and sediment control devices for construction and infrastructure — a broader incumbent that competes with Filtrexx in slope and channel applications.
• Tensar International (Tensar Corp): Tensar manufactures geosynthetics and mechanically stabilized earth (MSE) wall systems — overlaps directly with Filtrexx's GreenLoxx MSE wall/slope offerings, while being a much larger established geosynthetics platform player.
• North American Green: North American Green (a Profile Products brand) produces erosion control blankets and turf reinforcement mats — a closely adjacent competitor in slope and channel erosion control where Filtrexx's compost-based solutions also compete.
• Western Green: Western Green (a Tensar company) provides erosion control blankets, turf reinforcement mats, and sediment control products — a broader incumbent with overlapping slope/channel stabilization offerings for similar infrastructure end-customers.

Others

• Eastgate Sales & Distribution: Eastgate distributes compost filter socks and sediment control BMPs manufactured by other parties — comparable because it is one of Filtrexx's main distribution channels and competes at the distribution layer of the same construction BMP market.
