Unifilt Corporation

What Unifilt Corporation does

Unifilt Corporation is a privately held US specialty manufacturer of filter media and proprietary filtration equipment for potable and wastewater treatment facilities, founded in 1977 and headquartered in Wilkes-Barre, Pennsylvania. The company produces a complete line of filter materials — including its flagship Anthrafilt™ anthracite filter coal, filter sand, torpedo sand, coarse sand, Greensand Plus, high-density garnet, and support gravel — all meeting or exceeding AWWA B100-09 standards and certified under NSF/ANSI 61. Beyond commodity media, Unifilt designs and manufactures proprietary equipment such as the Air Scour modular units (304 stainless steel construction with trade-secret laser-cut microslits) and the Uni-Liner® injection-molded virgin HDPE underdrain rehabilitation system, alongside its UNIRATE dual-media system and Wheeler Balls product lines.

The company operates a vertically integrated, direct-to-customer model with no broker intermediaries. Revenue is generated from one-time sales of filter media and proprietary equipment, combined with professional services for filter media removal, installation, underdrain cleaning, evaluation, and 24/7 emergency repair. Pricing is quote-based and project-driven, with multi-year contracts typical; the sales motion is sales-led via toll-free phone lines, supported by company-owned multi-modal logistics (trucks, railcars, intermodal, and overseas containers) and field installation crews. Primary customers are municipal water and wastewater treatment plants, with secondary segments including engineering firms, construction contractors, and industrial users in process water, iron/manganese removal, and boiler condensate applications. The company has stated it has 'satisfied thousands of customers' since 1977 and self-describes as a global leader in filter materials systems.

Regional players

• ResinTech: Manufacturer of ion exchange resins and specialty filtration media for water treatment, primarily serving North American municipal and industrial markets. Comparable as a specialty media supplier with similar AWWA-standard products, though with greater focus on ion exchange.

Direct peers

• Parkson Corporation: Supplies drinking water and wastewater treatment equipment including DynaSand sand filters and other filtration technologies. Comparable as a filtration equipment manufacturer serving municipal water utilities with both media-based and engineered systems.
• WesTech Engineering: Provides water and wastewater treatment equipment including filtration systems, clarification, and process equipment to municipal and industrial markets. Direct competitor in municipal filtration equipment and turnkey solutions, though at significantly larger scale.
• F.B. Leopold Company: Manufacturers of underdrain systems, wash water troughs, and filtration media for municipal water treatment plants. Highly comparable to Unifilt's underdrain and filter media product portfolio, both targeting municipal drinking water utilities with engineered components.
• Tonka Equipment Company: Manufacturers of pressure filtration equipment and systems for municipal and industrial water treatment, including filter media and underdrain components. Closely comparable in scope and target customer base to Unifilt's filter media and underdrain portfolio.
• Graver Technologies: Manufactures filtration media, cartridges, and separation products for industrial and municipal water applications. Highly comparable in filter media manufacturing, materials specification, and municipal/industrial customer base.
• Hungerford & Terry: Designer and manufacturer of water treatment equipment including ion exchange, filtration, and process systems serving municipal and industrial customers. Comparable as a privately held, full-service water treatment equipment specialist with both products and services.

Broad incumbents

• Culligan International: Global water treatment company offering filtration, softening, and specialty media products. Adjacent in filter media but primarily consumer/SMB focused; relevant as a large-scale media and water-treatment incumbent.
• Evoqua Water Technologies (Xylem): Major provider of water treatment products and services, including filtration media, membranes, and engineered systems. A broad incumbent with significant overlap in municipal filtration but operating at far larger scale with diversified offerings.
• Severn Trent Services (Veolia): Global provider of water and wastewater treatment solutions including filtration, disinfection, and process equipment. A broader incumbent offering overlapping filtration and media products as part of a much larger water-services portfolio.
