What Air Quality does

AQ Group is a Netherlands-based specialist in maintenance, cleaning, inspection, and disinfection of climate and drinking water installations. Founded in 2002 (originally as Air Quality Improvement) and headquartered in Utrecht, the company operates multiple divisions spanning air handling (AQ Air Quality, AQ Air Socks), water treatment (AQ Water), cooling and heating (AQ Cooling), installation assembly (AQ Construct), air humidification (AQ Cumulus), and circular filtration products (AQ Circle-R), with a Belgian branch (AQ International, Herentals) serving the Belgian market.

The technical core combines proprietary products with field services. AEROSEAL® is a patented duct-sealing process that uses water-soluble sealant carried through ductwork as a fog to seal leaks internally, with 125,000+ duct systems sealed globally and airtightness up to class D (ATC 2). AQ Circle-R is a circular filter cassette system where only the filter medium is replaced, reducing filter-frame waste. AQ Cumulus RO equipment (co-developed with Cumulus) delivers reverse osmosis at 250 and 2,000 L/hr. The business sells these products and provides 24/7 emergency response, preventative maintenance, legionella management, and sustainability retrofits (EC fan replacement, heat recovery) — the latter positioned as the firm's contribution to what it calls the climate revolution in the Dutch HVAC sector.

AQ Group serves enterprise customers across education (Utrecht University), aviation asset management (KLM/4AMS, ~100 buildings), data centers (Global Switch, Vertiv), healthcare (Strukton Worksphere at Amphia Hospital), facility management (Sodexo), and technical installation contractors (Unica, BAM, SPIE, Kuijpers, Croonwolter&dros, Engie, Kropman). The go-to-market is direct field sales with tender participation for institutional clients and long-term preferred-supplier relationships with major MEP contractors. Revenue is not publicly disclosed; the firm is privately held under AQ GROUP BV with no external funding or M&A activity in the source data.
