Indoor air quality moved from a compliance line to a specification requirement after 2020, and filtration and ventilation demand has held rather than reverted. The equipment is unglamorous and the manufacturers are small, but the aftermarket (filters, service, commissioning) recurs against an installed base that only grows.

  • Moderate strategic-buyer pool: 27 firms exceed 500 employees, so a scaled asset has buyers, but not many
  • Post-pandemic IAQ a durable structural tailwind.
  • Energy-recovery ventilation and filtration growing.
  • Filter consumables provide recurring revenue.
