About this business

This is a specialty air filter manufacturer with over 30 years of operation, building custom and special-application filters, from HVAC and HEPA to cabin air and electronic-cabinet filtration, for customers across the country and around the world. The business was founded by an owner who grew up in the filter industry and carries more than 50 years of engineering know-how into every product. Its core strength is the ability to build non-standard sizes and specialty media filters that general suppliers cannot or will not make, which draws a loyal, diversified customer base that includes industrial, commercial, and technology-sector clients.

The operation runs Monday through Friday out of a single facility, with a team that averages five years of tenure and takes roughly 90 days to fully train. The owner is moderately involved, spending time across sales, production, and finance. After an outsized 2022–2023 in which two customers temporarily drove volume well beyond historical norms, revenue reset to the $1.7M range — and has since rebuilt on a deliberately broader base: 2026 is tracking toward roughly $2.0M, with earnings through October up sharply over the prior year and approximately $435K in open orders committed for delivery by year-end. The recovery has been driven by a sustained focus on service — on-time shipment on every order and same-day quoting — that brought long-standing customers back and continues to attract new ones. The owner notes meaningful further upside in marketing and quality-program development that a new owner could pursue.

The owner founded the business in 1992 and, at 75, is ready to step back and pass the operation to someone who can carry it forward. He is willing to remain available for questions for up to 12 months to support a smooth transition.
