An Added Layer of Disinfection After Wiping — Reaching the Air, Walls, and the Spots UV Can't See
Facing staff turnover and the line-of-sight limits of UV, the Environmental Services team at Piedmont Henry Hospital added hypochlorous dry misting as a final step after surface wiping. Here's what their Environmental Services Manager reports about coverage, ATP swabbing, cost, and training.

Turnover, Plus the Line-of-Sight Limits of UV
In a hospital, environmental services carries enormous weight — and it carries it through constant staff turnover. Every new hire has to be trained on protocol, and the more steps and devices in the routine, the harder consistent training becomes.
The team had also been working with UV. UV is a line-of-sight technology: it treats the surfaces its light can actually reach. Anything in shadow — the underside of equipment, the back of a wheel, the air itself, ventilation, the wall behind a cart — sits outside the beam. The Environmental Services team wanted broader coverage they could add after wiping, without adding a long, hard-to-train process.
A Final Layer That Fills the Room, Not Just the Beam
GEIA dry misting disperses hypochlorous (HOCl) — the same molecule the human immune system produces — as a 1–3 micron mist. Instead of treating only what a light can reach, the mist fills the full volume of the room: the air, the walls, ventilation, wheels, and the floor. It runs after the team has wiped surfaces down, as an added layer in the existing routine — clean, address high-touch points, then mist — never as a replacement for surface cleaning.
For an Environmental Services team managing turnover, the appeal was as much operational as environmental: a step that's fast, that covers the whole area, and that's simpler to train than a line-of-sight device.
What the Environmental Services Manager Reports
"The primary reason is that fogging, using hypochlorous, provides more coverage within the area within 3–5 minutes and is an additional level of disinfection after wiping all surface down. It will cover the air, walls, ventilation, wheels, floor etc. it takes least time to use than UV light (UV uses line of site).
ATP swabbing results are equal to if not better than UV light.
It is more cost effective than UV light system device.
It also simplifies training with staff."

Four Things That Changed for the Team
More Coverage, Faster
The manager reports the mist "provides more coverage within the area within 3–5 minutes" — reaching air, walls, ventilation, wheels, and floor, not just the surfaces in a beam's line of sight.
ATP Swabbing Results
In the team's own verification, "ATP swabbing results are equal to if not better than UV light." We report this as the customer's measured experience.
More Cost Effective
The manager reports the approach is "more cost effective than UV light system device" for their facility.
Simpler Staff Training
With turnover a constant in environmental services, a step that "simplifies training with staff" pays off every time a new hire joins the team.
A Layer at the End — Never a Replacement for Cleaning
Clean
The team runs its standard cleaning protocol. Surfaces are wiped down first — exactly as before.
High-Touch
High-touch points get the attention they always have. The existing routine stays intact.
Mist
Hypochlorous dry misting runs last as an added layer — reaching the air, walls, ventilation, wheels, and floor in 3–5 minutes.
GEIA dry misting is step three. It works alongside standard cleaning practice — it does not replace it.
