Rensa Filtration

What Rensa Filtration does

Rensa Filtration is a vertically integrated commercial and industrial air filtration manufacturer headquartered in Aurora, Illinois, backed by Audax Private Equity since 2022. The company produces a comprehensive portfolio spanning standard pleated, mini-pleat HVAC, HEPA (99.97%-99.99% efficiency at 0.3 microns), V-bank, pocket, metal, and carbon/odor configurations, with proprietary branded product lines including PreVent air intake protection, CarbonWeb carbon filtration, SuperFlo HEPA, Endurex, Revolution Pocket, and Adsorball. Operating at a scale of approximately 12 million filters manufactured annually across 42,000+ product SKUs, the company employs 1,000+ air filtration experts across manufacturing, distribution, custom filter solutions, and installation/replacement services in North America and, since September 2025, Europe (via the IREMA-Filter GmbH acquisition).

The business model is B2B hardware sales executed through a direct field sales force targeting facility managers, mechanical contractors, OEM manufacturers, and building owners, complemented by a broad distributor and reseller network that includes the company's acquired regional distributors (The Filter Shop, Air Filters Northwest, Air Filtration Co.). Rensa also pursues an OEM-embedded go-to-market for custom configure-to-order and engineer-to-order filtration integrated into customer equipment such as EV charging stations and automotive assembly plants. Customer verticals are diversified across healthcare, data centers, automotive and EV, food and beverage, commercial and public buildings, industrial manufacturing, and power generation, with end-customer logos including Honda Marysville Auto Plant, an EV charging network, a Minnesota grocery chain, and a Seattle hospital. Since 2022, the company has executed ten acquisitions to broaden product capabilities (metal filters via Smith Filter, carbon via D-Mark and IREMA-Filter media), geographic reach (Portland via Air Filters Northwest, Germany via IREMA-Filter, Midwest via The Filter Shop), and distribution density.
