What class 1 air does
Class 1 Air is a Milwaukee-based, employee- and founder-owned provider of air filtration products and controlled-environment testing and certification services for regulated facilities. The company operates as a single-source supplier serving pharmaceutical and biotech manufacturers, hospitals and healthcare facilities, medical device producers, food and beverage processors, research laboratories, semiconductor fabrication sites, and aerospace manufacturers. Its customer base exceeds 500 businesses across 23 states, concentrated in the upper Midwest with field offices in Milwaukee, Madison, and Chicago.
The company's product portfolio spans pleated air filters (MERV 8-13), bag filters in multiple efficiency classes per ISO 16890, V-style and box-style filters, HEPA/ULPA filters compliant with EN 1822, ISO 29463, and IEST-RP-CC001, carbon and molecular filters for gas-phase filtration, cleanroom terminal air filters, HEPA filter housings with bag-in/bag-out containment, and UV germicidal lighting. Service offerings include cleanroom testing and certification to ISO 14644, USP 797/800 compliance testing, biosafety cabinet certification to NSF-49, fume hood testing to OSHA/ANSI/ASHRAE, laminar flow and isolator testing, IQ-OQ-PQ validation, ISO 8573-compliant compressed air quality testing, microbiological laboratory services under ISO 9001, and duct and coil cleaning. The technical basis is metrology-driven: HEPA integrity testing using PAO or PSL challenge media, particle counting, airflow visualization, and chamber pressure and velocity measurements, executed by a team of 100+ certified technicians averaging 10 years of industry field experience.
The business model combines recurring professional-services revenue (annual or semi-annual compliance retesting cycles driven by FDA, USP, ISO, and cGMP requirements) with consumable product sales of filtration media and equipment. Go-to-market is enterprise field sales: technicians are dispatched to customer sites for on-site certification, repair, and maintenance work, supported by phone and website lead capture and location-targeted SEO across Wisconsin, Illinois, Indiana, and Michigan. The company has been recognized by Inc. Magazine as one of the 5,000 fastest-growing privately held companies in the U.S. and operates within the Scientific Safety Alliance (SSA) family of seven controlled-environment service companies. Pricing is quote-based and not publicly disclosed.
