Reopening after Covid-19 

The success of the economic recovery from Covid-19 will depend on two crucial factors; 
1. The public sentiment regarding the safety of public places and businesses
2. How well businesses put in place the safety measures that assure customers and employees

Safety First

Making sure the customers and employees feel safe is important for all businesses, but is critical for businesses such as hotels, restaurants, retail stores, health clubs, schools, and childcare centers which routinely cater to a large number of people.

CDC has provided general guidelines to assist businesses to establish protocols and procedures to disinfect frequently-touched surfaces in workspaces and public-facing areas, such as points of sale, counters, furniture, common areas, guestrooms, equipment, restrooms, door push bars, door handles. It recommends to frequently wipe down such worker and customer-facing equipment to prevent contamination and infection.

Special Challenges for Hospitality and Retail

The state-mandated shelter-in-place and lockdown restrictions, which limited travel and general movement of people, have hit the Hospitality and Retail sectors the hardest. Further, the pandemic has also placed personal safety foremost on people’s minds as they start thinking about traveling, dining out, and shopping.  Clearly, it will not be going back to “business as usual” when customers begin to trickle in.

The definition of customer experience is changing. Beyond cleanliness and quality service, the customers will expect the hotel, restaurant, or retail store to feel safe to visit. The same applies to the employee expectations as they return to back to work. They too would want to know that measures have been taken to keep the safety from the spread of germs top of mind.

 It will be particularly challenging and expensive to keep all the employee and customer touchpoints continuously sanitized and disinfected in accordance with the CDC and OSHA guidelines. Nonetheless, failure to ensure the safety of customers and employees is not an option.  The success of the business will hinge on how safe and comfortable customers and employees feel about the place.  

In the new normal, businesses will need to be ready to meet the new set of expectations and ensure that guests feel not only comfortable, but also safe. As consumers feel trepidation about visiting places with high frequency of occupant turnover, guests will look with fresh eyes for signs that the guestrooms, lobby, restaurant/bar seating is clean and fresh. Even stuffy and stale air would give wrong signal and discourage a guest from patronizing otherwise sanitary facilities. Various methods, such as makeup air, air fresheners and air deodorizers are unable to take care of all types of pollutants in the air.

Disinfecting the areas with traditional methods has its own issues.

Though the special focus on safety from the Covid-19 threat is new, businesses have been implementing various strategies such as advanced HVAC systems with makeup air provisions to control the CO2, NO2, VOC levels, and special housekeeping procedures to ensure to maintain healthy indoor air and the environment.  Keeping the indoor air healthy is a challenge even during normal circumstances due to various pollutants that affect the occupant’s health, comfort, and productivity.  it is even more challenging due to the limitations and cost of these measures during and after the pandemic.

  • It is expensive to schedule people around the clock to such duties
  • Disinfecting chemicals add the VOC to the already compromised indoor air1
  • Makeup air systems indirectly reduce the CO2, VO2, VOC level by bringing in fresh air indoors but do little to mitigate the virus, bacteria, and fungi in the environment
  • The manual process of regular and frequent disinfecting is labor intensive which makes it expensive and prone to human error

Negative ions increase the flow of oxygen to the brain; resulting in higher alertness, decreased drowsiness, and more mental energy

Negative ions are odorless, tasteless, and invisible molecules that we inhale in abundance in certain environments. Think how refreshing we feel near mountains, waterfalls, and ocean. In our bloodstream, negative ions are believed to produce biochemical reactions that increase levels of the mood chemical serotonin, helping to alleviate depression, relieve stress, and boost our daytime energy.

Enficiency NPBI creates healthy indoor air by increasing the concentration of Negative Ions to 1000-1200 per cm3 of air.

Plasma Air Ionization Proven to Reduce Coronavirus Surrogate MS2 Bacteriophage by 99% in Independent Spanish Testing

Successful certified testing conducted in a building facility proves virus destroying power 

Testing carried out by Tayra and backed by the Spanish Ministry of Defense Biological Laboratory in Spain has proven the effectiveness of Plasma Air Ionization technology in the reduction of MS2 Bacteriophage, a surrogate for SARS-CoV-2 (COVID-19), in indoor environments.

There is mounting research to suggest that clean, disinfected air plays a vital role in preventing the spread of SARS-CoV-2, the virus causing COVID-19. While respiratory droplets are considered the primary transmission route, aerosols are being considered by many health authorities as a possible mode of infection transmission along with surface contact. This suggests that viral particles can remain suspended in the air for long periods and can be inhaled.

The research tests were conducted in a Madrid hotel converted into a residence and confinement center for medical staff during the pandemic. The experiments took place in simulated ICU hospital rooms within the hotel. This environment was explicitly designed to test air ionization on small aerosolized viral particles. The laboratory analysis was carried out at a nearby operations center of the Spanish Ministry of Defense from May 4th to May 14th. 

The Plasma Air ionizer was chosen to suit the specific airflow and installed in the entrance to the fan coil unit of the supply Air Duct test space. The bacteriophage MS2 was then nebulized into the test space. During the two distinct phases of the test, the supply air entering the test room was ionized using Plasma Air’s bipolar ionization system. In contrast, during the second phase, the supply air into the room was untreated. A reduction of approximately 2 log units of the Bacteriophage was obtained in the air that was ionized by the Plasma Air system. This corresponds to a 99% reduction after only 10 minutes of exposure to ionization.

The research project was guided and coordinated by Plasma Air’s long-term business and technical partner in Spain, Tayra, a specialist in air purification. In addition to the Spanish Government ministries, the experiments also involved academics in the fields of engineering, microbiology, and computational fluid dynamics, along with Spanish Government appointed testing labs.  

The tests also included using manikins to simulate ICU patients. The manikins were equipped with specialized filters to measure the amount of Bacteriophage that was being breathed in with and without air ionization. The levels of MS2 Bacteriophage and associated particle counts were measured using Electrical Low-Pressure Impactors, and swabs were taken from walls and surfaces for analysis. The level of airborne MS2 Bacteriophage was measured using the Spanish authorities calibrated equipment for detecting biothreats. Results from this test showed a reduction in the order of 0.70-0.85 log pfu/cm2 corresponding to nearly 80% reduction in surface MS2 Bacteriophage after 10 minutes between the test with and without ionization.  

“Coronavirus is a global crisis and nowhere more so than inside built environments such as transport hubs and work environments,” explains Chris Russell, Vice President of Plasma Air. “The effective elimination of airborne virus is a major breakthrough that can make workplaces, transport, entertainment and educational facilities safer for employees, commuters and students.”

“We were very motivated to facilitate these critical tests at our laboratories here in Madrid, and we are extremely impressed by the results achieved,” Lieutenant Coronal Juan Carlos Cabria, the Technical Director of the biosecurity laboratories of the Ministry of Defense, stated. “We are extremely grateful to the team of Scientists, Engineers, Microbiologists and Academics who have worked tirelessly here for the last three weeks voluntarily to achieve this incredible and important result in the battle against Coronavirus.”
