Frequently Asked Questions – TOMI SteraMist Environment System

What is the TOMI SteraMist Environment System, and how does it work?

The TOMI SteraMist Environment System is a transportable whole-room iHP fogging decontamination platform that uses TOMI’s patented Binary Ionization Technology (BIT™) to convert a less-than-8% hydrogen peroxide solution into 0.05–3 micron ionized hydroxyl radical particles that disperse through the treated space like a gas, achieving 6-log reduction (99.9999%) efficacy against bacteria, bacterial spores, viruses, and fungi by penetrating surfaces, recesses, and areas that liquid disinfectants and manual wipe-down protocols cannot effectively reach. The system operates three applicators simultaneously to ensure consistent room coverage at a standardized dose rate of 0.5 ml per ft³, with automated cycles controlled remotely via an intuitive HMI that generates downloadable cycle data for regulatory documentation and SOP validation. It is categorized within ARES Scientific’s portfolio of environment decontamination systems for whole-facility disinfection applications.

How long does a full room decontamination cycle take with the SteraMist Environment System?

For a reference room volume of 3,663.7 ft³ (104 m³), the SteraMist Environment System completes the iHP fogging application phase in under 45 minutes, with the complete cycle — including contact time and aeration — finished in just over 75 minutes, enabling rapid room turnover for terminal room decontamination between patient care episodes, post-production pharmaceutical suite cleaning, and outbreak response scenarios where minimizing room downtime is operationally critical. This total cycle time is significantly shorter than many vaporized hydrogen peroxide (VHP) room decontamination systems, which require extended aeration phases to reduce residual peroxide concentrations to safe re-entry levels before personnel can return to the treated space. Actual cycle times will vary based on room volume, geometry, HVAC configuration, and treatment protocol requirements specific to the facility’s validated SOP.

How does the SteraMist Environment System compare to VHP room decontamination?

Both SteraMist iHP and vaporized hydrogen peroxide (VHP) systems use hydrogen peroxide as the active decontamination agent, but they differ in concentration, particle physics, cycle speed, and equipment requirements in ways that make iHP a more practical choice for many laboratory and healthcare settings. The SteraMist system uses less than 8% hydrogen peroxide — far below VHP concentrations — and generates an ultra-fine 0.05–3 micron ionized fog that disperses rapidly throughout the room without requiring the sealed, pressurized environments or dedicated exhaust infrastructure that most VHP generator systems demand; aeration after a SteraMist cycle is also faster since lower peroxide concentrations decompose to safe levels more quickly. The non-corrosive residue-free iHP chemistry is additionally more compatible with sensitive laboratory equipment, reducing the need for equipment removal and protection steps that add significant time and labor to VHP room decontamination workflows. Facilities that also need material-level transfer decontamination can pair the Environment System with the SteraMist SteraBox pass-through decontamination chamber for a complete contamination control strategy.

What types of facilities and rooms is the SteraMist Environment System designed for?

The SteraMist Environment System is designed for any facility requiring validated whole-room disinfection with minimal equipment preparation, room modification, or extended downtime, including hospital patient rooms and isolation units for terminal room decontamination between admissions, pharmaceutical manufacturing suites and cleanrooms requiring periodic or pre-qualification room fogging, BSL-2 and BSL-3 biosafety laboratory spaces, vivarium animal housing rooms and procedure areas, blood bank and clinical laboratory spaces, morgue and pathology suites, and cannabis processing and testing facilities. Its transportable design and standardized 110/120V electrical requirement make it deployable across virtually any room type within a facility without specialized installation, and its configurable cycle programming supports facility-specific SOP development across diverse contamination control program requirements.

Is the SteraMist Environment System safe to use in rooms with sensitive laboratory equipment?

Yes — the SteraMist Environment System’s iHP chemistry is specifically designed to be non-corrosive, residue-free, and compatible with a wide range of materials including electronics, laboratory instruments, cell culture equipment, analytical instruments, plastics, and other sensitive assets that would be damaged by liquid chemical fogging agents, chlorine dioxide, formaldehyde, or high-concentration VHP systems. Unlike many room decontamination technologies that require extensive pre-treatment equipment protection, removal of sensitive instruments, or covering of exposed surfaces, the SteraMist iHP fogging process allows treatment of occupied equipment spaces in most standard laboratory and healthcare room configurations, reducing the labor and preparation time required before and after each decontamination cycle. Users should consult TOMI’s material compatibility guidance and establish validated protocols confirming compatibility for specific equipment configurations in their facility.

What is the difference between the SteraMist Environment System and the SteraMist SteraBox?

The SteraMist Environment System is designed for whole-room, facility-scale iHP fogging decontamination of entire spaces — treating all surfaces, air volumes, and equipment within a room simultaneously — while the SteraMist SteraBox is a stainless-steel decontamination chamber designed for item-level or material-level decontamination of supplies, equipment, and materials that must be treated before transfer into controlled environments such as cleanrooms, pharmaceutical suites, and vivarium barrier facilities. The two systems use the same BIT™ iHP technology and achieve the same 6-log reduction efficacy, but address different points in a facility’s contamination control workflow: the Environment System handles room-level terminal and periodic disinfection, while the SteraBox handles point-of-entry material transfer decontamination. Many facilities deploy both systems together to create a comprehensive contamination control program that addresses decontamination needs at every level of the facility operation.
