REair is a research and development company in the field of eco-technologies for the purification of outdoor and indoor air in buildings, through the reduction of pollutants and the sanitization of surfaces.
REair’s products and solutions improve Indoor Air Quality (IAQ) and allow buildings to stay cleaner, reducing maintenance and cleaning costs.

REair created and patented the eCoating system: a coating, transparent, nanotechnology, environmentally friendly, 100% Green.
Activated by the combination of light and air (Photocatalysis), eCoating continues over time to proactively decompose bacteria, viruses, molds, fungi, VOCs, organic NOx PM and other harmful pathogens.
The reaction allows pollutants in the air to be broken down into harmless by products such as carbon dioxide and water molecules.
With the same system, microorganisms such as bacteria, viruses, algae, and molds can be inactivated and killed.
eCoating by REair is the only product of its kind on the market and is applicable on any surface and in any environment, both indoor and outdoor.
