What Filter Systems does
Filter Systems is a privately held wholesale distributor and e-commerce retailer of HVAC, paint, and controlled-environment air filters, founded in 1997 and headquartered in a 25,000+ sq ft warehouse at 9000 Sovereign Row, Dallas, Texas. The company distributes the Glasfloss Z-Line® series of extended-surface pleated air filters — available in MERV 10, MERV 11, and MERV 13 efficiency ratings — as well as cartridge replacements compatible with Honeywell, AprilAire, Trion Air Bear, Goodman, and Amana OEM systems. Core technology rests on 100% synthetic fiber media, galvanized expanded metal reinforcement, moisture-resistant separators, electrostatic gradient structures (MERV 13), and UL std. 900-classified construction rated to 180°F.
Revenue is generated through two streams: one-time product sales via the filterstm.com e-commerce storefront (with free shipping across the Continental USA) and unit-based pricing of roughly $99–$242 per filter, plus a recurring turnkey Air Filter Replacement Service that bundles facility surveys, automated scheduling, and professional technician visits on a quote-based contract. Go-to-market combines direct-to-consumer e-commerce for residential/SMB buyers with a sales-led motion for enterprise accounts, supported by NAFA-certified specialists and a company-operated fleet of trucks and vans for just-in-time delivery in the DFW metroplex. The customer base spans Residential, Commercial, Industrial, Medical, Educational, and Municipal segments, with primary supplier Glasfloss Industries (a 100% employee-owned Dallas manufacturer operating a 423,000 sq ft facility since 1936) anchoring the supply chain.
