What Airinum does
Airinum is a Stockholm-based consumer health technology company founded in 2015 by Alexander Hjertström (CEO) alongside co-founder Fredrik Kempe (CMO), operating under the legal entity Astir Impact AB. The company designs and sells reusable air-protection hardware built on a proprietary multi-layer filter stack combining HEPA filtration with an activated carbon layer, validated at the RISE Research Institutes of Sweden to 98-99.9% efficiency against particles down to 0.3μm and 99.99% against PM2.5, and certified to the GB 2626-2006 KN95 standard (functionally equivalent to N95/FFP2).
The product portfolio centers on three mask lines (Urban Mask 2.0 at $79, Lite Mask at $49, Kid Mask for ages 3-7 at $29, plus the Air Mask Active), a portable personal air purifier launched in March 2024 called the Hale ($189) with a 500-hour HEPA+carbon filter, 7-level airflow and up to 24-hour battery life, and a recurring-revenue replacement filter line (Urban, Lite, Kid, and Hale filters) plus accessories such as the Polygiene ViralOff-treated Necklace Bag, head straps, and exhalation valves. Distribution is direct-to-consumer via a multi-currency Shopify storefront with a US warehouse for North American fulfillment, supplemented by Amazon marketplace and a B2B/corporate-gifts sales motion; filter subscription plans run on 3-, 6-, or 9-month cadences.
The company targets multiple horizontal consumer segments — urban commuters, allergy sufferers, parents of young children, health-conscious professionals, frequent travelers, pet owners with allergies, and populations exposed to wildfire smoke — and has pursued a lifestyle-brand positioning through collaborations with premium fashion labels (Human Made, Bally, Woolrich, TAKAHIROMIYASHITA The Soloist) and high-profile endorsers (Gwyneth Paltrow, Pharrell Williams, Alan Walker, Rita Ora), supported by an Eden Reforestation tree-planting partnership and broad earned media coverage. As of October 2025, Airinum has announced an ownership transition and is conducting a Final Sale of remaining inventory with no returns accepted, indicating an exit or restructuring event despite continuing operations.
