REair

What REair does

REair S.r.l. is an Italian cleantech company founded circa 2015 and headquartered in Via Montenapoleone 10, Milan, with a USA branch in Beverly Hills, California. The company commercializes a patented photocatalytic coating technology branded 'eCoating by REair' — a transparent, nanotechnology-based, '100% Green' coating that uses only light and air to decompose atmospheric pollutants (NOx, VOC, PM) and microorganisms (bacteria, viruses, molds, fungi) into harmless substances such as water. The product portfolio spans outdoor coatings (Photo Coat, Photo Coat Green, Photo Active Plus, Hydro Active — for building facades, monuments, glass, and photovoltaic panels) and indoor coatings (Original Plus, Photo Active, Medical Indoor, Original Gold disinfectant) for walls, porous surfaces, glass, ceramics, steel, and healthcare-grade disinfection. The eCoating Medical Indoor line is certified for SARS-related virus reduction.

Complementing the coatings is the AIRSENSE platform, a network of compact, plug-and-play environmental sensors (PM1/PM2.5/PM10, gases, TVOC, radon, CO2, T, P, RH, light) with cloud data transmission via GSM and API integration to building management systems (BMS). REair also owns the REair Original Gold sub-brand for professional surface disinfection. Underlying technology is validated through partnerships with the Universities of Turin, Sapienza (Rome), Milano-Bicocca, and Milan, plus certification entities SouthAgro, Artest, and GREENGUARD; abatement calculations are validated by the University of Turin.

The business model is B2B, with distribution exclusively through a certified installer network rather than direct-to-consumer sales. Installers must complete education modules on air quality measurement methodology, certified instrumentation usage, and application techniques before being authorized to apply REair products professionally. Target customer verticals are infrastructure (municipal buildings, facades, monuments), medical/healthcare (hospitals requiring certified antibacterial/virucidal air purification), education (schools, universities), and hospitality (hotels, restaurants). Revenue mechanics are primarily one-time product sales through the channel, plus professional installation services and AIRSENSE hardware sales. Pricing is not publicly disclosed. The company is registered as a PMI Innovativa (Innovative SME) in the Italian Business Register as of 31/03/2025 and was admitted to the Smart&Start Italia government funding program on 10/12/2020. Registered capital is €109,288.11; the company is privately held with Raffaella Moro listed as President and CEO. Geographic footprint spans Europe and North America, though specific installed-base metrics and contracted revenue figures are not disclosed.

Core offering

REair develops, produces, and distributes photocatalytic coatings (eCoating) for air purification and surface sanitation of buildings, applicable on any surface in indoor and outdoor environments. The coatings are sold as physical chemical products (PHOTO COAT, PHOTO COAT GREEN, PHOTO ACTIVE PLUS, HYDRO ACTIVE, ORIGINAL PLUS, PHOTO ACTIVE, Medical Indoor, REair Original Gold) alongside the AIRSENSE air quality monitoring sensor platform. Distribution occurs exclusively through a network of certified installers trained in air quality measurement and application techniques.

Product overview

REair offers eCoating by REair, a patented photocatalytic coating system, available in two main product lines: outdoor coatings (PHOTO COAT, PHOTO COAT GREEN, PHOTO ACTIVE PLUS, HYDRO ACTIVE) for building facades and glass surfaces, and indoor coatings (ORIGINAL PLUS, PHOTO ACTIVE, Medical Indoor) for walls and interiors. All eCoating products operate through light- and air-activated photocatalysis to continuously decompose pollutants and pathogens. Complementing the coatings is the AIRSENSE platform — a network of environmental sensors and cloud-based monitoring for real-time air quality measurement, which can interface with building management systems via API.
