The organisms that drive risk here
- MRSA and Staphylococcus aureus — persistent on dry surfaces
- Clostridioides difficile — spore-forming, the hardest routine target
- Norovirus — outbreak organism in care settings
- SARS-CoV-2 and respiratory viruses
- Pseudomonas and Legionella in water systems
Controlling these is not primarily a chemistry problem — it is a consistency problem. The chemistry that fails an audit is almost never the chemistry that was specified; it is the chemistry as actually mixed, at the concentration actually present, on the schedule actually followed. Onsite generation removes the largest single variable by producing the solution at a set concentration every time.
Where it is used
- Terminal cleaning of patient rooms and treatment areas
- High-touch point programmes on the daily schedule
- Electrostatic fogging of rooms between occupancy
- Equipment surface disinfection
- Wound care irrigation with appropriate grade product
- Water system treatment
- Long-term care communal areas
What it replaces
- Quaternary ammonium disinfectants with sensitisation concerns
- Bleach wipes with odour, corrosion and tolerability problems
- Hydrogen peroxide vapour systems requiring room evacuation
The honest position: none of these products are useless, and each has applications where it remains the right choice. What changes with onsite generation is the default — the bulk of routine sanitation moves to a chemistry that is cheaper per litre, safer to handle, gentler on equipment and impossible to run out of.
Compliance and audit position
- EPA-registered disinfectant required for most protocols — HOCl-AS200, Reg. No. 101112-1
- CMS infection control conditions of participation
- Joint Commission environment of care standards
- State licensing and infection prevention requirements
Full citations and downloadable material are on the regulations page, and the sector-specific research citations are collected in the research hub.
Where the money comes from
- HAI reduction is the return that matters, and it is measured in reimbursement
- Staff tolerability reduces complaints and turnover in environmental services
- Faster room turnaround where fogging replaces manual-only cleaning
- Lower corrosion cost on equipment and fixtures
White paper
Onsite Hypochlorous Acid in Hospitals sets out the cost case, the evidence and the compliance guardrails in eighteen pages: where hospital disinfection money goes, what the HOCl-AS200 label covers and what it does not, contract pricing for hospital groups, and what onsite generation does not fix.

Implementation SOP
The written procedure for this sector, in sequence:
- Clean thoroughly before disinfecting — this is where C. difficile protocols fail
- Use the EPA-registered product where the protocol requires registered claims
- Observe the five-minute contact time on the registered label
- Extend concentration and contact time for spore-forming organisms
- Fog rooms between occupancy with electrostatic coverage
- Verify, document and audit against your infection prevention plan
The step everyone skips
Precleaning. Hypochlorous acid is an oxidiser, and oxidiser consumed by organic soil is not available to kill anything. A programme that sanitises dirty surfaces will underperform regardless of what the label says.
Questions
Which system do we need for a healthcare & senior care operation?
It depends on daily volume and peak draw rather than on facility size. Most single-site operations in this sector are served by the EcoloxTech 300; multi-line and high-volume operations move to the EcoloxTech 1200 with buffer storage.
Do we need the EPA-registered product as well?
If your protocol, auditor, insurer or regulator specifies an EPA-registered disinfectant, then yes — HOCl-AS200, Reg. No. 101112-1. Many sites run both: generated solution for volume cleaning and sanitising, registered product where the claim must be on a label.
How do we prove it works to an auditor?
Baseline environmental swabs before implementation, the same swabs afterwards, concentration verification records, and the citation pack from our research hub. That combination is evidence rather than assertion.
What is the payback period?
It depends on your current chemical spend and volume, but most commercial installations in this sector recover the equipment cost inside the first two years, and often considerably sooner once the second-order savings are counted.
