To improve the air quality and remove advanced contaminants from the air by providing an optimal guest experience in each hotel room within the hotel.


AtmosAir’s systems were installed and tested in multiple hotel rooms where there was no existing air purification previously.


AtmosAir was tested in identical guest rooms at the Marriott Residence Inn in Chicago.

An Atmos Air room and another “control” room was left unoccupied while the air conditioners ran continuously.
After 2 days, air quality testing was done in each rooms. Results showed a 93% reduction in TVOCs in the AtmosAir room, compared to the control room.

TVOCs are irritants and gaseous elements or chemical compounds released by cleaning products, furniture, carpeting, adhesives, paint and lacquer, as well as outside emissions.

The AtmosAir tests proved that AtmosAir can significantly impact air quality in as little as 2 days.
