ViraWarn by Opteev is the first affordable respiratory virus detector for personal spaces. Think of it as a personal space smoke alarm but for respiratory virus. ViraWarn by Opteev is a tabletop device that monitors your personal spaces and instantly alerts of the presence of respiratory viruses including COVID-19, RSV, and Influenza.

Alerts of potential respiratory virus presence via a flashing red LED light.

Monitors your personal space on your desk at work, or at home on a coffee table or dining table while having visitors over.

Independent lab tests demonstrate a near 100% accuracy.

How It Works

Advanced Biosensor That Detects
Respiratory Viruses In Your Personal Space

Virus Particles Are Charge Carriers

Viruses have genetic material made of nucleic acids. These nucleic acids have a partial negative charge because of their phosphodiester bonds. The protein coat of the virus is made up of amino acids which can be neutral, negative, or positive in charge.

Biosensors + Polarized Medium

An intake fan at the top of the device pulls air in from your personal space. If a virus particle is present, a change in conductivity and a fluctuation in electrical parameters will occur when it interacts with the polarized liquid medium.

Change In Conductivity Occurs

If virus particles are present in your personal space, a change in conductivity and a fluctuation in electrical parameters will occur when the particles interact with the polarized liquid medium.

Data Analyzed By AI Processor

That electrical data is then analyzed by specialized Artificial Intelligence algorithms to filter out false readings, decide threshold values, and determine the result.

Signal Sent to User

A positive or negative result is then sent to the user in the form of a RED-positive or GREEN-negative flashing LED light.

"Amazing product. Great customer service. I use it at school during lectures and labs. When people come to my house they sit near the ViraWarn Patriot for a small amount of time before we interact. Thanks to this product we can feel safe. I tell everyone how wonderful it is."

"The ViraWarn Patriot has been the best investment for my office. I have spent thousands of dollars over the past two years on cleaners, UVC machines, masks and gloves all in an effort to keep my employees and customers safe. I love that this machine can finally give my customers the confidence to bring their families and high risk children into my office without fear. It give me such joy to see families interacting together again."

"Well it actually does work. After months of wondering, our family caught BA.5. It seems to be about as sensitive as a rapid test."

ViraWarn by Opteev is the first affordable COVID-19 screening device for breath. Think of it as a personal space smoke alarm but for COVID-19. ViraWarn is able to detect particles of COVID-19, any of its variants, or Influenza in your personal space and trigger an LED alarm. ViraWarn is affordable, small in size, and easy to use. Simply turn it on and ViraWarn will monitor your personal spaces and alert when these unique virus particles are present.

ViraWarn’s proprietary Charge Transference (CT) Technology is a combination of advanced biosensors, Edge artificial intelligence, and proprietary algorithms. CT Technology uses the charge transfer complex of spike protein viruses in an engineered media of high resistivity. When batches of a spike protein virus drift through the engineered media they produce characteristic electrical polarizability which is detected by ViraWarn’s advanced biosensors. The resulting signal is then analyzed for pattern matching through the Edge AI and proprietary algorithms to avoid false-negative and false-positive responses.

ViraWarn monitors personal spaces and detects viruses with spike proteins. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus behind the worldwide outbreak of COVID-19 disease. One of the key biological characteristics of SARS-CoV-2, as well as several other viruses, is the presence of spike proteins that allow these viruses to penetrate host cells. Other viruses that have these unique spike proteins besides SARS-CoV-2, and all of its variants, are Influenza, coronaviruses, and H1N1. ViraWarn is able to monitor personal spaces and detect these dangerous spike protein viruses.

ViraWarn’s incredible Charge Transference Technology detects the electrostatic signature of spike protein viruses. COVID-19 and Influenza are both viruses with this unique signature. ViraWarn is not able to tell the difference between COVID-19 and Influenza in personal spaces, but is able to detect Coronaviruses in your personal space and will instantly trigger its alarm to warn of the presence.

No, ViraWarn is intended to monitor personal spaces in indoor settings only.

No, ViraWarn is intended to monitor your personal spaces only, such as at your desk at work, or on your coffee table or dining table while you have visitors over. It is not intended to monitor the air of a room.

No, ViraWarn is not intended to be used as a breathalyzer or to screen people entering a room. It is intended to only monitor your personal spaces such as your personal space at your desk at work or your personal space while you have visitors around your coffee table or your personal space at your dining table. ViraWarn could potentially malfunction if users are blowing directly into the device.

Yes, disinfectant sprays and charcoal filters could potentially contaminate ViraWarn’s liquid media if discharged near the device. Please do not use cleaning sprays near ViraWarn and please do not use devices that utilize charcoal filters near ViraWarn.

ViraWarn monitors personal spaces and alerts of the presence of COVID-19 and Influenza in that personal space. It does not pinpoint an infected individual and it does not alert of infection, rather it is a detection device that monitors your personal space.

Yes, ViraWarn was tested in hundreds of homes through the world during multiple variant exposures (Delta and Omicron) and has been shown to be highly effective because it does not rely on users instruction sets. It has also been tested in government sponsored labs in two countries and those results were supplied to Opteev independently and confirmed that ViraWarn was 100% effective in reporting viral particles in personal spaces. ViraWarn is presently in an extensive clinical trial as well.

Yes. ViraWarn has been extensively tested with symptomatic and asymptomatic COVID-19 patients in home isolation and in hospitals. This real-world data shows ViraWarn’s incredible efficacy and accuracy at detecting COVID-19 in personal spaces, even for asymptomatic patients.

Yes. ViraWarn uses an engineered liquid media of high resistivity in order to detect viral particles in your personal spaces. A visual indication, via an LED light on the front of the unit, will notify when it is time to refill the reservoir.

Currently ViraWarn is single voltage and runs on 110-120V.

No. ViraWarn monitors and detects spike protein virus particles in personal spaces. It does not kill them. When the viral particles enter the device, they are neutralized in the specialized liquid media; however, ViraWarn does not neutralize the particles in the air outside of the device. ViraWarn is a monitoring and detecting device, not a disinfecting device.

ViraWarn can be taken to any personal space indoors it is needed in. Simply place the unit on a stable, flat surface, plug the device into an electrical socket, turn the unit on, and viral detection monitoring for personal spaces begins immediately. ViraWarn is currently not battery powered.
