The Same Molecule Your Immune System Makes. Now Treating the Room.
GEIA dry misting works because of two things, layered together: a chemistry your body has been producing for hundreds of millions of years, and an application method that fills the full volume of a room. This page is the working brief on both.
Hypochlorous Acid (HOCl) Is What Your White Blood Cells Use.
When a neutrophil — your immune system's frontline white blood cell — encounters a pathogen, it generates hypochlorous acid (HOCl) inside its phagosome using an enzyme called myeloperoxidase. The HOCl breaks down the pathogen, and then breaks down itself into harmless byproducts. This is a hundreds-of-millions-of-years-old defense mechanism running inside every healthy human body.
The HOCl used in commercial sanitation is the same molecule. It's produced either electrochemically (by passing a small electrical current through a salt-and-water solution) or by dissolving an EPA-registered tablet formulation (like 3.3g or 6.5g Tablets) in water. Both routes produce stable, ready-to-apply hypochlorous solutions.
- pH ~6.5 — near-neutral, no harsh acid or alkaline burn
- No detectable smell at typical use concentration — no perfumes, no chemistry note
- Leaves no residue — breaks down to saline (salt water) with no surface film
- Safe in occupied spaces — no PPE escalation, no evacuation required for most facility applications
- Compatible with food-contact surfaces — subject to the specific chemistry registration in use
A 1–3 Micron Mist Fills the Room. A Wipe Cloth Doesn't.
Wipes and sprays treat what you can reach. Dry misting treats what you can't. GEIA equipment atomizes hypochlorous solution into 1–3 micron particles — small enough to remain airborne for minutes, large enough to settle as a dry mist on every surface, into every corner, between every rack and crevice.
1–3 Micron Particle Size
Small enough to fill the air. Large enough to settle on surfaces. For context: a human hair is about 70 microns; E. coli is about 2 microns.
Whole-Room Coverage
A single cycle treats the air, the ceiling, the HVAC grilles, the fabric, the equipment housings — at the same time, in the same cycle.
A Wet Application — Without Wet Surfaces
It is a wet application — hypochlorous is a liquid — but the 1–3 micron mist is so fine it settles and evaporates without leaving surfaces damp or wet: no standing water, no surface film, no rinse-down required. The room is ready when the cycle ends.
Two Different Things, Regulated Differently.
GEIA builds the equipment that disperses HOCl. We do not formulate, register, or make efficacy claims about chemistry. That distinction matters because the EPA regulates chemistry, not equipment — and any claim about what an HOCl solution will or won't do to a specific pathogen is tied to the EPA registration of that specific chemistry, not to the misting equipment.
The Equipment (What GEIA Makes)
- AYRUS, LUVIAN, ROGE — dry misting hardware
- Atomizes HOCl solution into 1–3 micron mist
- Application method, not a chemistry registration
- Designed for the protocol, not the kill claim
The Chemistry (What Distributors Supply)
- 3.3g Tablets, 6.5g Tablets — EPA-registered HOCl tablets
- Other EPA-registered HOCl tablets and ready-to-use solutions
- HOCl generators producing electrochemical HOCl
- Efficacy claims sit here, attributed to the specific registration
Your distributor will help you select the chemistry that fits your jurisdiction, your industry, and your specific protocol. Across most industries, GEIA equipment runs the same way regardless of which EPA-registered HOCl chemistry is in the reservoir.
How HOCl Compares to Other Sanitation Chemistries
Each chemistry has its place. HOCl is the right answer when you need ongoing environmental treatment in occupied spaces, with no harsh smell, no surface damage, and no residue. Bleach and quats remain appropriate for specific high-load, hard-surface, between-cycle applications.
What You Need to Know to Run a Real HOCl Program.
Concentration Matters
GEIA equipment is designed to operate up to about 300 PPM free chlorine. Most facility protocols target around 294 PPM at the point of dispersion. Your distributor will help dial in the right concentration for your industry and your chemistry.
Shelf Life Is Real
HOCl is most stable when freshly prepared. Tablet formulations are shelf-stable for extended periods in tablet form, but the prepared solution has a finite working life. Your protocol will specify mixing frequency.
Equipment Maintenance
A simple descaler cycle every 6 months keeps GEIA equipment running cleanly. AYRUS units use replaceable ionizer coins on an annual cadence. Total ongoing maintenance: minutes per unit per month.
Clean First. Always.
HOCl dry misting treats the environment — it does not remove visible soil. Standard cleaning protocols still come first. GEIA is built to work alongside what your team already does, never to replace it.
