About American Metal Filter
American Metal Filter HVAC & Range Hood FiltersAMFCO
American Metal Filter Company (AMFCO) began operations in a two-car garage in San Diego, California, on February 27, 1986, when third-generation filter manufacturer Val Deilgat started the business manufacturing replacement range hood filters for appliance parts distributors. The company landed its first OEM contract in 1992, a relationship that continues today.
As AMFCO grew beyond range hood filters, it added commercial and industrial metal air filters serving HVAC wholesalers, filter distributors, and other filter manufacturers. The business weathered a serious setback in 2006 when it lost 42% of gross sales to Chinese manufacturers and nearly faced bankruptcy, prompting Brandon and Val Deilgat to refocus the company on its core manufacturing competencies in 2007.
Today AMFCO manufactures air filters for both OEM appliance makers and aftermarket HVAC wholesalers, with a product range spanning wholesale metal mesh filters, washable furnace filters, range hood filters, and HVAC metal air filters, backed by more than 55 years of combined family experience in filter manufacturing across two U.S. production plants. ChatMRO helps appliance repair technicians and HVAC distributors match filter dimensions and mesh specifications against the American Metal Filter catalog, and our team supports RFQ submissions for distributor-volume orders.

Frequently asked questions
Are American Metal Filter range hood filters washable and reusable?
Yes — American Metal Filter's washable furnace and range hood filters are designed as reusable metal mesh alternatives to disposable fiberglass or paper filters, which can reduce long-term replacement costs. Confirm your exact hood or furnace model's filter dimensions when ordering.
What's the difference between a baffle filter and a mesh filter for a range hood?
Mesh filters use layered metal screens to trap grease particles as air passes through, while baffle filters use angled metal plates that force air to change direction, causing grease to condense and drain away — baffle filters are generally considered more effective for heavy grease loads. American Metal Filter produces both styles depending on the OEM specification.
Does American Metal Filter supply both OEM and aftermarket replacement filters?
Yes — the company holds long-standing OEM contracts dating back to 1992 while also supplying the aftermarket through HVAC wholesalers and filter distributors. This dual focus means the same filter specifications used in original appliances are often available as direct aftermarket replacements.
Where are American Metal Filter products manufactured?
AMFCO operates two U.S. production plants, continuing a manufacturing approach that began in a two-car garage in San Diego in 1986. Domestic production has been part of the company's recovery strategy since refocusing on core competencies in 2007.
How do I find the right American Metal Filter replacement without an exact model number?
Describe the filter dimensions, mesh or baffle style, and whether it's for a range hood or furnace, and ChatMRO's AI will match it against the indexed American Metal Filter catalog. This is especially useful for appliance technicians replacing a filter in an older range hood without the OEM part number on hand.
