Frequently Asked Questions

About the Product

What is Gringard Pure?

What is Grignard Pure™?

Grignard Pure™ is a rigorously tested EPA approved continuous, antimicrobial air treatment solution that is expected to kill more than 98% of SARS-CoV-2 virus particles in the air, when people are present, and where the CDC has told us that transmission is most likely.

Grignard Pure is the only EPA-regulated solution that provides continuous protection, killing virus particles as they enter the air from talking, coughing, sneezing – significantly reducing what is the primary cause of infection.

How does Grignard Pure work to kill COVID-19?

Simple engineering, AI technology and Grignard Pure. A dispersion unit is either integrated into the existing HVAC system or set up as a “portable” installation. Grignard Pure goes into the dispersion unit, which aerosolizes it where it is then be circulated through the air handler or directly into the space. Small, wall mounted sensors are placed in the space that monitor the flow and concentration of Grignard Pure in the air and send the data back to the controller on the dispersion unit, for remote monitoring.

Is Grignard Pure a new product or does it just have a new name and “use”?

The use of Grignard Pure as an effective tool to combat the spread of COVID-19 is new. Products similar to Grignard Pure have been used safely all around us for over 20 years. If you have been to a Broadway play, a live music performance, or a stage show at a theme or amusement park, you’ve probably “seen” the product in use. For example, event producers use the product to create lighting and other effects that add to the overall experience.

How does Grignard Pure kill the Sars-CoV-2 virus?

Grignard Pure delivers what is called “continuous intervention,” which simply means that the air treatment solution is constantly working to fight against the virus. The Grignard Pure solution is aerosolized and forms a vapor in the air that actually condenses on virus particles and permeates into it, disrupting the protein and membrane structure of the virus with its amphiphilic properties. What this simply means is that Grignard Pure can kill the virus as the pathogenic particles leave the person from talking, coughing, sneezing – significantly reducing what is the primary cause of infection.

Do you have third party endorsement?

Distinguished public health academics, doctors and other professionals have all studied and endorse the results. In particular, Grignard Pure has assembled a (non-paid) team of leading engineers, public health experts, academics and doctors. These include Gediminas “Gedi” Mainelis, PhD and Donald W. Schaffner, PhD (Rutgers, The State University of New Jersey); Emmanuel Goldman, PhD (Rutgers New Jersey Medical School); Gurumurthy “Ram” Ramachandran, PhD (Johns Hopkins University); Jack Caravanos, PhD, CIH (NYU School of Public Health; Toni Choueiri, MD (Harvard Medical School); and Antony Galione, MA PhD FRS FMedSci (University of Oxford).

 

Does the solution have an odor or leave a residue?

No, Grignard Pure does not have an odor or leave a residue.

Product Safety and Effectiveness

How safe is it?

The EPA reviewed all available data on this product’s safety and concluded that it does not pose any health risks of concern. 

We have put Grignard Pure through rigorous safety testing. Government and other third party testing have shown the active ingredient in Grignard Pure to be safe. Studies conducted by the U.S. Centers for Disease Control’s National Institute of Occupational Safety and Health (NIOSH) and assessment by the EPA indicates the active ingredient in Grignard Pure is safe with no toxicological endpoints identified by adverse effects.

Additionally, hundreds of millions of people around the world have been exposed to products with properties identical to Grignard Pure over the past 20 years. That includes a range of places from museums to conventions to banquets, entertainment venues and more.

 

How was it tested for safety and efficacy?

Grignard Pure worked with frequent EPA third-party testing lab Microchem to conduct two separate tests to prove that it kills more than 98% of Sars-CoV-2 virus particles in the air where transmission is most likely.

Intrinsik, a globally-recognized scientific and regulatory consulting firm providing expert regulatory and toxicology advice, conducted a Toxicology Risk Assessment which confirmed the product is safe for use, when used as directed and a population is exposed for extended periods of time.

Maintaining airborne concentration levels of between 0.5mg/m3 to 3mg/m3  kills the SARS-CoV-2 virus. All independent testing has confirmed that only when levels reach the threshold of 1000 mg/m3 do they begin to pose an exposure danger to humans.

 

What about people who are immuno-compromised?

The safety of air treatment products like Grignard Pure is demonstrated by their long history of use with no significant health concerns reported. NIOSH concluded that an air treatment product like this did not affect people with asthma.  The EPA has said that the active ingredient in Grignard Pure is not expected to cause adverse effects when inhaled, although temporary irritation to eyes, nose, and throat may occur to sensitive individuals. 

 

How will people know they are entering a space where Grignard Pure is being used?

Locations using Grignard Pure will prominently display the “Treated with Grignard Pure” seal at major entrances. This gives people who might have questions about their own health the clear option not to enter the facility should they not feel comfortable, and to advise them to get fresh or outside air if irritation occurs.

 

How much Grignard Pure needs to be in the air to be effective? And was that level tested for safety?

The concentration of Grignard Pure that needs to be in the air to be deemed effective is between 0.5mg/m3 and 3mg/m3. This equates to a non-visible or very light haze, and the effectiveness and safety of these levels were both addressed in our independent laboratory testing. For comparison, the amount that would need to be in the air to even begin to approach levels that would warrant potential concern is 1000mg/m3.

 

Do people that handle Grignard Pure need special training? If so, will training sessions or materials be provided?

Grignard Pure requires that anyone selling, installing or using the Grignard Pure system complete online training courses. You can learn more about the courses and how to access them by calling 1 (855) 642-PURE (7873).

 

Does the presence of Grignard Pure eliminate the need for PPE?

We believe that Grignard Pure can be the final, key component of a complete COVID-19 safety strategy that includes social distancing, mask-wearing, and proper hygiene. It does not replace the need for PPE but by reducing the COVID-19 particles in the air, it definitively lowers the risk of transmission.

 

Does PPE reduce the effectiveness of Grignard Pure?

Absolutely not. Grignard Pure complements the use of PPE and in fact when Grignard Pure is present in indoor environments where people are using PPE, the risk of transmission is significantly reduced due to the effectiveness of Grignard Pure in reducing the viral load in the air. 

 

Is Grignard Pure effective against variations or mutations of the COVID-19 virus? Has it been tested on variations or mutations of the COVID-19 virus?

Yes. Under the EPA’s Section 18 Public Health Emergency Exemption, Grignard Pure is approved for use in killing the SARS-CoV-2 virus, including variants of it as well.

Product Availibility

What approval has been secured for Grignard Pure? Where can it be used?

We have a Section 18 Public Health Emergency Exemption from the U.S. Environmental Protection Agency (EPA) for the states of Georgia and Tennessee. That means that Grignard Pure can be sold to, and used by, people in those two states only. Within those states, Grignard Pure can be used in the following listed indoor spaces (occupied or unoccupied) when adherence to current public health guidelines (e.g., CDC guidance at www.cdc.gov recommending social distancing, limited occupancy, and increased ventilation) is impractical or difficult to maintain. Areas of particular concern include breakrooms, locker rooms, bathrooms, lobbies, elevators, eating areas, and food preparation areas within:

    • Health care facilities (e.g., hospitals, nursing homes, medical offices, dental offices), but not in resident / in-patient rooms, emergency rooms, operating rooms, or intensive care units; 
    • Intrastate buses, trains, and subways;
    • Food processing (NAICS 311) but not food services (NAICS 722);
    • Indoor spaces within buildings, including government facilities, where people are conducting activity deemed essential by the state and allowed by the state lead agency

 

What industries are utilizing Grignard Pure right now?

We are taking a very considered and cautious rollout within each scenario to ensure that we get it right by working with industry leaders such as Luminator for mass transit, and SS White Dental for dental offices. Successful rollouts in these areas will set the stage for large-scale deployments in the near future.

 

Why is it only approved for certain states? When can we expect more state exemptions?

We know there are numerous other states preparing to file applications with the EPA for Emergency Exemption approval. We understand the EPA will be overseeing an effectively managed rollout to ensure management of supply for operations deemed essential by each state. It is expected that other state applications for Section 18 Emergency Exemption will soon be filed.

If you are an official representative of a State government seeking more information on now to submit an application for a Section 18 Emergency Exemption, we can take your contact information and follow up with you.

 

Is a national approval in the works?

Grignard Pure is in discussions with the EPA to pursue a national approval which would cover all indoor activities.

 

Can Grignard Pure be used on viruses other than COVID-19?

The Section 18 Public Health Emergency Exemption allows for the use of Grignard Pure as an antimicrobial air treatment against COVID-19 in approved use sites. We are in discussions with the EPA to secure a national-level approval that would allow the use of Grignard Pure against other viruses and for a variety of use cases. 

 

How does Grignard Pure compare to other treatment solutions on the market?

Grignard Pure is the only EPA-approved antimicrobial air treatment solution. While in use, Grignard Pure works continuously, killing more than 98% of SARS-CoV-2 virus particles in the air where transmission is most likely. There are numerous technologies and products making claims about effectiveness in mitigating the spread of COVID-19. We have done extensive research into these solutions and have analyzed modes of operation, product claims and product drawbacks.

 

Why can’t we use surface disinfectants?

Over-the-counter disinfectants perform what is called “hard surface, non-porous” disinfection. Many of these types of products may be EPA-approved, but only for “episodic intervention” and they also don’t address the virus particles in the air. Grignard Pure delivers “continuous intervention,” constantly working to kill SARS-CoV-2 virus particles in the air, even as new particles are introduced into a space.
