Marriott's Autograph Collection Hotels and The Ritz-Carlton are installing bipolar ionization technology from Plasma Air in their properties' HVAC systems to help neutralize viruses, such as COVID-19.

The Plasma Air technology has been proven to help reduce MS2 bacteriophage, a surrogate for SARS-CoV-2 (the virus causing COVID-19) by 99 percent.

El Paso's historic Hotel Paso del Norte, Autograph Collection, is located in the city's downtown district. It re-opened after a four-year, multi-million-dollar renovation and includes added safety features in the current pandemic age. The hotel, which initially opened in 1912, now uses Plasma Air's ionization technology throughout its HVAC systems.

The system delivers the ionization solution to all 350 guest rooms and public spaces – to deactivate airborne viruses safely. The Plasma Air system also reduces airborne bacteria, mold, odors and volatile organic compounds, proactively purifying the air around the clock without any harmful by-products or chemicals.

"We are among the first Marriott Autograph Hotels in the world to install a system that cleans the air to this level," said Carlos Sarmiento, the hotel's general manager. "COVID-19 created the necessity to enhance the air quality in all areas of the hotel. In 2020, there is no amenity greater than safety."


Set to open in 2021, the Ritz-Carlton at Paradise Valley in Scottsdale, AZ, also will feature the Plasma Air ionization systems. The 122-acre, $2 billion luxury development will include a 215-room resort and 81 residential villas. The villas will be the first property in the brand's portfolio to feature ionized air.

"The resort and all 81 residential Villas will have ionized air throughout, using the Plasma Air systems," said Jerry Ayoub, president of Five Star Development. "With the health issues we're facing in the world today, including Plasma Air ionization was a necessary addition to ensure the highest level of clean, safe airflow throughout the property."

Five Star purchased over 1,000 systems from Plasma Air to be installed throughout its residential living villas, resort, stores, dining, health, and relaxation spaces to reduce the risk of disease and infectious outbreaks, such as COVID-19.

The enhanced air ionization technology is the latest among many steps the hospitality industry has initiated to standardize processes meant to slow the spread of coronavirus
