Nanofiber technology filter is highly-efficient (up to 95%) on sub-micron particles, including bacteria and viruses. Researchers say filtered air can prevent aerosol transmission of the Coronavirus! Aerosols don't fall to the ground, but rather disperse throughout the air, getting diluted by air currents. The FFE System invention created a product that filters air currents resulting in diluting virus airborne transmissions to humans!

Simplicity makes it unbelievable and physics makes it tangible! FILTERED FORCE ENVIRONMENT MERV 16 RATING

The first of its kind product to help protect against airborne virus without using a face mask! We don’t drink contaminated water, why should we breathe in contaminated air? It's all about an environment of vented filtered air flow. The FFE System invention created a product that filters air currents resulting in diluting virus airborne transmissions to humans. The FFE System creates an environment that forces you to breathe filtered air and forces any available airborne virus to include COVID-19 away from your eyes, nose, and mouth. Yes, vaccines and face masks work against the Coronavirus, but the FFE System goes beyond what any single person can do to protect themselves by creating a personal Filter Force Environment. Ventilation is the key to re-imagine how critical air flow is in the fight against all viruses. Researchers say clean air can prevent aerosol transmission of the coronavirus. Aerosols don’t fall to the ground, but rather disperse throughout the air, getting diluted by air currents. Whether you use a face mask or face shield the FFE System will dramatically increase protection against airborne virus transmission. COVID-19 virus particle size is 0.125 microns. The FFE filter System protects down to 0.027 microns. Simple Physics: Airborne virus cannot fight against a stream of blowing air. A stream of continuous blowing filtered air will help protect you against inhaling any virus. CDC Recommends: Using a fan to reduce the number of virus particles in the air. Intended use: To help protect your eyes and inhalation against airborne virus. Benefits: Face mask free virus protection / Breathing is not restricted / Face shield protection / Reusable / No heat build-up / No seal check requirements / Voice is not muffled /Face is visible Information: COVID-19 aerosol particles can remain suspended in the air for minutes to hours. CDC acknowledged that COVID-19 spreads through airborne transmission. The FFE System uses an FDA approved filter with a 99.99% efficiency. Aerosols can travel deeper into other people’s lungs when breathed in, studies found that a smaller amount of influenza virus is needed to infect people when inhaled as aerosols rather than sprayed up the nose as droplets. The FFE System can operate 30 hours continuously before recharging. How does it work: Forces you to inhale filtered air. Forces aerosols away from your eyes, nose, and mouth by using filtered ventilated air flow. When you breathe out, talk, sneeze, or cough the respiratory droplets that carry any virus cannot pass through the plastic face shield/mask.

Frequent Questions Read Frequent Questions about Indoor Air and Coronavirus (COVID-19). Explore all EPA Frequent Questions related to Coronavirus (COVID-19). Spread of COVID-19 occurs via airborne particles and droplets. People who are infected with COVID can release particles and droplets of respiratory fluids that contain the SARS CoV-2 virus into the air when they exhale (e.g., quiet breathing, speaking, singing, exercise, coughing, sneezing). The droplets or aerosol particles vary across a wide range of sizes – from visible to microscopic. Once infectious droplets and particles are exhaled, they move outward from the person (the source). These droplets carry the virus and transmit infection. Indoors, the very fine droplets and particles will continue to spread through the air in the room or space and can accumulate. Since COVID-19 is transmitted through contact with respiratory fluids carrying the infectious SARS-CoV-2 virus, a person can be exposed by an infected person coughing or speaking near them. They can also be exposed by inhaling aerosol particles that are spreading away from the infected person. Transmission of COVID-19 from inhalation of virus in the air can occur at distances greater than six feet. Particles from an infected person can move throughout an entire room or indoor space. The particles can also linger in the air after a person has left the room – they can remain airborne for hours in some cases. Someone can also be exposed via splashes and sprays of respiratory fluids directly onto their mucous membranes. Spread may also sometimes occur through contact with contaminated surfaces, though this route is now considered less likely. See Science and Technical Resources related to Indoor Air and Coronavirus (COVID-19) or Indoor Air and COVID-19 Key References and Publications for technical information.

Indoor Air and Coronavirus (COVID-19)

This new definition of a unique non-contact airborne transmission mode has significant repercussions on public health interventions to break the chain of infection, specifically regarding the type of masks that we should wear indoors. The proposed unified mode of aerosol transmission implies that the traditional distinction of face coverings into those that provide source control (e.g., surgical masks that protect others from droplets emitted by the wearer, outward protection) and susceptible control (e.g., N95 respirators that protect the wearer, inward protection) should be reconsidered. Both types of face coverings provide inward and outward protection of varying degree depending on numerous factors including the size of the emitted respiratory droplet, the material they are made of, and how well they fit a person’s face. the spatial separation between two persons indoors. The current measure of standing one or two meters away from other people would not be enough in case of airborne transmission; the ventilation: if people are in an indoor environment that is not well ventilated, even a distance of 2 meters between people may not be enough. The efficiency of ventilation as a control measure depends on the ambient air velocity. In indoor ventilated environments, for higher ambient-air velocities, the infection probability decreases since droplets are rapidly removed (expose to the virus is minimized).

Updating public health interventions

Airflow strongly influences the transport of virus-laden aerosols (81) in contrast to droplets, which are rapidly deposited because of gravity. Aerosols in exhaled air tend to rise because the exhaled air is warmer than the environment (50), and their trajectories can also be influenced by the body’s thermal plume (81). Greater airflow outdoors contributes to greater dispersion, whereas indoors the airflow is restricted by the surrounding walls and ceiling. Ventilation rate and airflow patterns play an important role in airborne transmission of viruses in indoor environments (144–146). A study of rhinovirus transmission showed that a low ventilation rate increases the risk of exposure to virus-laden aerosols indoors (27, 28). An outbreak of COVID-19 in a high-rise apartment building occurred along vertically aligned units that were connected by a single air duct, demonstrating the risk of airborne transmission associated with shared air (147). Improving ventilation rates to reduce the carbon dioxide levels in under-ventilated buildings from 3200 parts per million (ppm) to 600 ppm (corresponding to an estimated increase of ventilation rate from 1.7 liters per second per person to 24 liters per second per person) has been shown to reduce the secondary attack rate of tuberculosis to zero

Airflow, ventilation, and filtration

To control infection spread, a new technique in hospital patient room ventilation is introduced; personal ventilation (PV). Personal ventilation is usually based on jets of air directed to a person’s face (Melikov, 2004). Different designs are designed where PV systems should always be supplemented with a general ventilation system

Personal ventilation to control airborne infectious diseases

EXPOSURE TO OTHERS

Small gaps between the surgical or N95 facemask material and skin will lead to substantial decreases in the overall filtration efficiency.

For aerosols filtration efficiency decreases by 50% for a relative leak area of only 1%.

Direct exposure to others would be 50%.

The FFE System exposure to others would be 1.9% or less.

Using The FFE System --- Helping Dilute Airborne Virus Transmission

Your entire face is vented with filtered air. You have no choice but to breathe-in clean filtered air. Any floating aerosol clouds will be immediately pushed away from your face at a high airflow rate resulting in diluting the virus. Increasing ventilation rate is believed to reduce the cross infection of airborne transmitted diseases by removing or diluting pathogen-laden airborne droplet nuclei. A higher ventilation rate can dilute the contaminated air inside the space more rapidly and decrease the risk of cross infection. When wearing a surgical mask, aerosols can enter through the gaps. The filtered airflow will not allow virus aerosols to enter, pushing them away causing the virus to dilute. The same will occur if you wore a face shield with or without wearing a surgical mask. The FFE System airflow rate is 4 to 5 mph. As personal ventilation is a relatively new concept in hospitals, there are only a few studies known by the author
of this article, testing the performance of these systems. In office situations personal ventilation is already
generally used and several studies (Cermak et al., 2006; Pantelic et al., 2009; Melikov, 2004) show that personal
ventilation will always be able to improve the inhaled air quality in rooms with mixing ventilation and indoor air
quality in rooms with displacement ventilation with regard to pollution emitted from the floor and from humanproduced contaminants. PV systems which supply clean air are able to decrease the inhaled pollutant
concentration by factors between 2 and 50 times compared with total-volume ventilation alone. Pantelic
concluded that PV is able to reduce the concentration of contaminated droplets in the inhalation zone and at a
distance wide enough from the index patient, the momentum of cough jets could be bend away. MERV 16 RATING is considered hospital level air quality.

Improved PV designs for disease control (FFE System)

Airborne transmission between two occupants using the FFE System will result in approximately less than 1% of direct exposure. In the context of COVID-19, new requirements are occurring in ventilation systems to mitigate airborne transmission risk in indoor environment. Personalized ventilation (PV) which directly delivers clean air to the occupant's breathing zone is considered as a promising solution. To explore the potentials of PV in preventing the spread of infectious aerosols between closely ranged occupants, experiments were conducted with two breathing thermal manikins with three different relative orientations. Nebulized aerosols were used to mimic exhaled droplets transmitted between the occupants. Four risk assessment models were applied to evaluate the exposure or infection risk affected by PV with different operation modes. Results show that PV was effective in reducing the user's infection risk compared with mixing ventilation alone.

As both the exhaled flow and the PVb air developed an upward direction as shown inFig. 13(b), the collision between the PV jet and the end part of the exhaled flow or the remaining suspended cloud of particles after exhalation was not as marked as that which occurred in scenario 1. A smaller proportion of exposed droplet nuclei was derived from direct exposure (56.7–72.7%).

As PV is a ventilation mode that directly interferes with a human microenvironment, the flow interactions within this microenvironment should be carefully considered to identify the best design for optimal infection control. Advanced PV designs should be developed to satisfy requirements for effective interventions in airborne transmission pathways at any point within the microenvironment, from where particles leave the infectious source to where these enter the breathing zone of another.

In this study it was found that the effectiveness of PV in protecting against infectious particle transmission largely depends on the extent to which PV entrains ambient infectious particles. If low entrainment of ambient air by PV can be realized, PV can deliver clean air with high efficiency directly to the breathing zone of the exposed occupant. PV ATDs with wider diameter that can achieve a longer clean air core are recommended for this purpose. When the jet's clean-air core is long enough to reach the occupant's breathing zone (BZ), the occupant can be effectively protected.

Guidelines from the CDC and the WHO recommend the wearing of face masks to prevent the spread of coronavirus (CoV) disease 2019 (COVID-19); however, the protective efficiency of such masks against airborne transmission of infectious severe acute respiratory syndrome CoV-2 (SARS-CoV-2) droplets/aerosols is unknown. Here, we developed an airborne transmission simulator of infectious SARS-CoV-2-containing droplets/aerosols produced by human respiration and coughs and assessed the transmissibility of the infectious droplets/aerosols and the ability of various types of face masks to block the transmission. We found that cotton masks, surgical masks, and N95 masks all have a protective effect with respect to the transmission of infective droplets/aerosols of SARS-CoV-2 and that the protective efficiency was higher when masks were worn by a virus spreader. Importantly, medical masks (surgical masks and even N95 masks) were not able to completely block the transmission of virus droplets/aerosols even when completely sealed. Our data will help medical workers understand the proper use and performance of masks and determine whether they need additional equipment to protect themselves from infected patients. IMPORTANCE Airborne simulation experiments showed that cotton masks, surgical masks, and N95 masks provide some protection from the transmission of infective SARS-CoV-2 droplets/aerosols; however, medical masks (surgical masks and even N95 masks) could not completely block the transmission of virus droplets/aerosols even when sealed.
