How Oxygen Coating Mimics the Human Lung to Clean Indoor Air
Breathe Better AIR
Indoor air quality is one of the most overlooked public health concerns of our time. While we worry about outdoor pollution, the air inside our homes, schools, hospitals, senior care centers, and offices are often two to five times more polluted, according to the EPA. Enter Oxygen coating, a revolutionary wall and ceiling paint infused with natural minerals that purifies air the way human lungs do.
Oxygen coating doesn’t just trap toxins; it actively neutralizes them, separating harmful molecules in the air and disabling biological threats much like the biological filtration system in our chest.
Let’s break down the science behind this.
The Chemistry of Purification: Breaking Down CO₂ and NOx
Oxygen coating is not your average paint. It’s a functional surface, meaning it chemically interacts with its environment. The magic happens at the nanoparticle level, where Zinc Oxide and Silver come into play.
Zinc Oxide Nanoparticles (ZnO NPs) are known photocatalysts. When exposed to ambient light (natural or artificial), they generate reactive oxygen species (ROS), essentially chemical scavengers. These ROS include hydroxyl radicals (•OH), superoxide anions (O₂•⁻), and hydrogen peroxide (H₂O₂). These highly reactive molecules break down volatile organic compounds (VOCs), carbon monoxide (CO), and nitrogen oxides (NOx), a group of harmful gases released from combustion, industrial activity, and even household items such as furniture and rugs.
Here’s how it works:
- Photocatalysis begins when light activates the ZnO surface.
- Electrons in ZnO get excited, leaving behind electron “holes.”
- These holes react with water and oxygen molecules in the air to form ROS.
- ROS attack pollutants like NOx breaking them down into harmless substances such as nitrates (NO₃⁻) and CO₂.
- In the case of CO₂, excess carbon can be captured on the surface and converted through secondary reactions or sequestered in benign forms.
Meanwhile, Silver Nanoparticles (AgNPs) act as both an antimicrobial agent and a catalyst booster. Silver disrupts bacterial cell membranes and viral envelopes, making it incredibly effective against biological contaminants. It also enhances the activity of ZnO by acting as an electron trap, preventing recombination of electrons and holes, thus improving the generation of ROS and boosting overall efficiency.
What makes Oxygen coating unique is that we have found a balanced formula between the two natural minerals that mimics what our lungs when it comes to producing clean air.
Biological Contaminant Defense: A Parallel with the Lung
The human lung is one of the most finely tuned biofilters on the planet. It takes in air, separates oxygen from harmful gases, traps particulates through mucus and cilia, and neutralizes biological invaders through immune cells like macrophages.
In a similar way, the Oxygen coating:
- Filters out toxins through catalytic reactions.
- Neutralizes viruses, bacteria, and mold spores using Silver’s biocidal properties.
- Protects the brain and immune system by reducing the overall burden of air contaminants that would otherwise cause inflammation, neurotoxicity, and systemic stress.
Airborne pathogens and fine particulate matter can cause chronic stress on our immune system and have even been linked to neurodegenerative diseases. The lungs protect us from this, and now walls coated with Oxygen paint do too.
What’s especially striking is the parallel in how both systems prevent oxidative stress. The lung uses antioxidants and immune cells to fight off inflammation and intruders. The Oxygen coating mimics this via ROS that target pathogens and pollutants without releasing harmful residues. The result is a self-sustaining, passive purification system embedded into the very structure of the room.
So, What’s the Impact?
Imagine every square foot of your home actively working to clean the air—reducing your risk of asthma, allergies, and long-term exposure to harmful pollutants. This isn’t just about comfort; it’s about long-term cognitive and immune health. Clean air means sharper thinking, better sleep, and stronger resistance to illness.
In essence, Oxygen coating turns the passive surface of a wall into an active lung. It’s a new chapter in the clean tech and health tech crossover a quiet, invisible technology that’s always working, just like your lungs. Only now, your walls are breathing with you.
