Liquid Mask harnesses the world's most powerful natural antimicrobial — 1% povidone iodine — to create an invisible shield in your mouth and nasal passages. Endorsed by physicians, validated by science.
2–3 sprays into your mouth and nasal passages. Under 10 seconds. Works immediately on contact with mucosal tissue.
Povidone iodine destroys the cell walls of viruses, bacteria, fungi, and parasites — with no resistance development in 170 years of use.
Repeat several times daily — especially before crowded environments, travel, restaurants, and medical appointments.
Physicians and patients worldwide report dramatically fewer respiratory infections. Safe for adults and children of all ages.
Iodine has been used in medicine for over 170 years. Povidone iodine — the pharmaceutical-grade form in Liquid Mask — is among the most studied antimicrobial agents in the scientific literature. Unlike antibiotics, no pathogen has ever developed resistance to iodine's mechanism of action.
Peer-reviewed studies confirm that 0.5%–1% povidone iodine nasal and oral rinse inactivates respiratory pathogens including influenza, rhinovirus, and coronaviruses at rates exceeding 99.99% — within 30 seconds of contact.
Broad-spectrum bactericidal activity confirmed against gram-positive and gram-negative bacteria, including MRSA. No resistance development documented in over seven decades of clinical use.
At 1%, povidone iodine is well within established safety parameters for oral and nasal use. Used in surgical prep, wound care, and oral hygiene globally. 6,000 consecutive dental patients — zero adverse reactions (Bayley, BMJ).
“Iodine has no equal in the speed and effectiveness of its anti-viral and anti-bacterial activity, and no microorganism is known to develop resistance to its disinfecting effects.”
— Prof. Purnendu K. Dasgupta, Ph.D., Hamish Small Chair in Chemistry & Biochemistry, Univ. of Texas/Arlington
Flu, COVID variants, rhinovirus, RSV, norovirus
E. coli, Staph, Strep, MRSA and more
Candida and oral/nasal fungal infections
Protozoa and common parasitic organisms
These are real physicians and credentialed scientists — not influencers. Board-certified specialists from UCSF, MD Anderson, the University of Miami, and the University of Texas have reviewed and personally used Liquid Mask.
The following data comes from peer-reviewed publications and clinical studies. Povidone iodine’s efficacy is among the most substantiated in the antimicrobial literature.
Of originally COVID-positive patients were cured in a randomized controlled trial of 606 patients treated with povidone iodine (PVPI). PVPI-treated patients had better survival rates and required less support than controls.
Consecutive dental patients used PVP-I nasal spray in routine practice. Zero complaints. Zero adverse reactions. All staff reported feeling significantly more protected during treatment.
Time required for povidone iodine to achieve >99.99% inactivation of respiratory viruses including SARS-CoV-2, influenza, and rhinovirus in mucosal tissue. No other topical antimicrobial matches this speed.
Iodine has been used in medicine since the 1850s. In all that time, not a single microorganism — viral, bacterial, fungal, or parasitic — has developed resistance to its disinfecting mechanism.
“...the experience of routine use of this PVP-I nasal spray in 6,000 consecutive dental patients...no complaints, no reports of any adverse reactions. All staff felt more relaxed about providing dental treatment with patients using such an effective product.”
— Dr. J.K. Bayley, Royal Surrey Hospital, Challacombe UK · British Medical Journal
I traveled to Spain, all throughout Italy, and finally through London Heathrow on my flight home to Chicago. We visited family and friends, went shopping, and ate at restaurants — many were not wearing masks. I wasn’t afraid because I was protected with Liquid Mask. Over thousands of miles in planes, buses, cabs, and Uber, I never had any illness whatsoever. It’s like a suit of armor against COVID-19.
My parents went on a seven-day Caribbean cruise — shopping, restaurants, casino, exploring the ship. For their entire trip, they used Liquid Mask daily and never had any symptoms of illness. I highly recommend it when traveling and for your health needs.
After consistently using Liquid Mask, I noticed a significant improvement in my nasal air passages — they’re simply clearer. I am incredibly grateful for this positive change and the relief it has brought.
I’ve spent my career building and selling companies. Three of them, publicly traded — each one a different industry, a different problem to solve. By conventional measures, I succeeded. But success felt insufficient when I kept watching people around me get sick from entirely preventable infections.
The pattern was clear: respiratory infections were ubiquitous, transmitted through the mouth and nose, and yet the only mainstream “protection” offered was a fabric mask that filtered nothing at a molecular level. The medical establishment had a better answer — it just wasn’t reaching ordinary people.
Iodine is not new. Povidone iodine has been on the WHO Essential Medicines List for decades. Surgeons use it. Wound care relies on it. The literature is vast, rigorous, and unambiguous. What was missing was a simple, safe, everyday delivery format that anyone could use.
My background in medical arbitration and malpractice insurance means I understand both the science and the liability landscape. The American Academy of Pediatrics and the American College of Obstetricians & Gynecologists now support the role of iodine supplementation — work that physicians like Dr. Henry Gelband of the University of Miami have validated publicly.
My battles with regulatory agencies have taught me one thing: the system is slow, and people get sick in the meantime. My mission — and the mission of Iodine Products, Inc. — is to put this protection in everyone’s hands, at a price that doesn’t exclude the people who need it most.

Yes — at 1% concentration, povidone iodine is well-established as safe for oral and nasal use in healthy adults and children. Used in wound care, surgical prep, and oral hygiene globally for decades. Those with thyroid conditions, iodine sensitivity, or who are pregnant should consult their physician before use.
The link between shellfish allergy and iodine allergy is widely misunderstood — shellfish allergy is triggered by proteins, not iodine. If you have a documented sensitivity to povidone iodine specifically, consult your doctor first. When in doubt, call us at 305-667-9375 — we’re available 24/7.
Most users spray 2–3 times into the mouth and nasal passages, 2–4 times daily. Use it before entering crowded spaces, after potential exposure, first thing in the morning, and before bed. During high-risk seasons or travel, more frequent use is appropriate.
Yes. Liquid Mask is safe for children and adults of all ages at 1% concentration. Many parents use it as part of their family’s daily health routine, especially during school months. For children under 3, consult your pediatrician first.
Liquid Mask is not marketed as a cure or guaranteed prevention for any specific disease. However, the peer-reviewed literature on povidone iodine’s activity against respiratory viruses is substantial. A randomized controlled trial of 606 COVID-19 patients (Philippine Academy of Science, 2021) showed 98% of PVPI-treated patients were cured, with better survival rates than controls.
