American Metal Filter

What American Metal Filter does

American Metal Filter Company (AMFCO) is a privately held, family-owned manufacturer of reusable metal air filters, filter holding frames, and ASHRAE-rated side-access filter housings, founded in February 1986 in a garage in San Diego, California. The company designs and produces a broad catalog spanning electrostatic pleated filters (MERV 6 and MERV 8), metal mesh filters, foam filters, mist eliminator filters, media-pad holding frames, universal and HEPA holding frames, and proprietary RaptorSeal side-access housings capable of supporting 1,000 to 20,000+ CFM. Manufacturing relies on semi-automated turret press and press-brake operations, in-house R&D, and patented frame technology (Talon Lock construction); the company holds UL Classified 900 certification on the H9B series frame. AMFCO's customer base is split between two primary channels: direct sales to Original Equipment Manufacturers requiring custom blueprint filters designed into proprietary equipment, and aftermarket HVAC wholesalers purchasing standard and custom replacement filters. No minimum order requirement is imposed, and the company operates two production plants — San Diego, CA and Nashville, TN — that together provide 2-day ground transit coverage to 90% of the US population.

AMFCO's revenue model is exclusively hardware sales across four product streams: air filter sales, filter holding frame sales, ASHRAE housing sales, and custom OEM manufacturing. Pricing is quote-based for both standard and custom products with publicly disclosed pricing unavailable, and the GTM motion is a B2B sales-led approach combining enterprise field sales for OEM contracts with phone and website-driven quote-based selling for wholesale accounts. The company is led by Val Deilgat (President/CEO), his son Brandon Deilgat (VP of Sales, USD graduate, CAFS and NCT certified), Dave Carter (COO, joined 1997), and Michelle Carter (VP of Client Fulfillment, joined 2009). Notable historical events include a 2006 near-bankruptcy from Chinese import competition that triggered a 2007 strategic refocus, a 2003 acquisition of Air Cleaning Environmentalists (ACE), a 2014 Nashville expansion, and a 2020 essential business designation during COVID-19 for hospital filter production. In 2024 the company consolidated its offerings into a full line of Filters, Frames, and ASHRAE Housings.

Direct peers

• Camfil: Camfil is a global leader in air filtration with deep coverage of MERV/HEPA filters, holding frames, and housings for commercial and industrial HVAC. It is a direct competitor to AMFCO's OEM and aftermarket filter, frame, and ASHRAE housing lines.
• Koch Filter: Koch Filter manufactures HVAC air filters, holding frames, and housings sold through OEM and wholesale channels in North America. Its product mix and distribution model closely mirror AMFCO's OEM-plus-aftermarket strategy.
• Filterbuy's Air Filter Manufacturer: Filterbuy is a US-focused manufacturer and online seller of HVAC air filters, including MERV-rated and custom filters, primarily serving wholesalers and contractors. It competes with AMFCO in aftermarket HVAC distribution, though its media is non-metal.
• Filtration Group: Filtration Group manufactures air filtration products, frames, and housings for HVAC and industrial applications. It competes with AMFCO across both OEM and aftermarket channels in commercial and industrial segments.
• AAF Flanders: AAF Flanders is one of the largest US manufacturers of HVAC and industrial air filtration products, including metal filters, frames, and housings. It directly competes with AMFCO across OEM and aftermarket channels for both standard and high-efficiency filtration.

Broad incumbents

• Donaldson Company: Donaldson is a diversified industrial filtration manufacturer with significant HVAC and air filtration product lines. While broader than AMFCO, it competes in industrial and commercial air filters and dust collection equipment that overlap with AMFCO's industrial filter business.
• Mann+Hummel: Mann+Hummel is a global filtration leader with HVAC and indoor air quality product lines. Although predominantly automotive, its air filtration/MERV product families overlap with AMFCO's commercial and industrial filter offerings.
• Parker Hannifin (HVAC Filtration): Parker Hannifin's HVAC/Industrial gas filtration division manufactures filters, frames, and housings for commercial and industrial HVAC systems. It overlaps with AMFCO in OEM-grade air filtration and side-access housings as part of a much broader portfolio.
• 3M (Filtrete): 3M's Filtrete brand is a leading consumer and light-commercial HVAC air filter line. It competes primarily with AMFCO's electrostatic and MERV filters in residential/light-commercial channels but lacks AMFCO's metal and OEM custom capabilities.

Regional players

• Air Kontrol (historical reference): Air Kontrol, a filtration equipment auctioneer/manufacturer based in Batesville, MS, is referenced in AMFCO's own history as the source of production equipment acquired in 1999. Operates in the same metal filtration/industrial dust collection space in the US.
