The Halo Disinfection System®

Eliminating Pathogens that a Less Effective Disinfectant Solution Leaves Behind

The proliferation of new whole room disinfection technologies has provided infection control professionals many options for protecting their staff and the public from pathogens. But not every disinfectant solution is equal.

Halosil’s Halo Disinfection System® pairs HaloMist, a proprietary broad spectrum disinfectant, with the HaloFogger® to ensure the uniform, dry fogging delivery of disinfectant throughout any complex space, achieving complete coverage with the highest possible efficacy on the market today.

Here’s How it Works

The HaloFogger generates a turbulent aerosol that uses evaporation to quickly disperse H202 vapor and increasingly concentrated micro-droplets everywhere in complex rooms to kill germs where they hide, ensuring our proprietary HaloMist formula reaches even those spaces beyond the reach of sprays, wipes, or UV lights. Specialized HaloFogger options and assemblies empower disinfection leaders to achieve uniform coverage and efficacy in a variety of settings.

HaloFogger® STD

The HaloFogger delivers complete surface disinfection throughout any room with the press of a button, delivering a precise amount of disinfectant solution to eliminate pathogens in a myriad of complex spaces found in healthcare, long-term care, and life sciences facilities, as well as in daycares, schools, athletic facilities and more.

HaloFogger® FLX

The HaloFogger FLX provides flexibility in nozzle positioning while maintaining the precision of broad spectrum disinfectant delivery. The base FLX unit can be located outside the room being treated while the detachable nozzle assembly operates inside the room, enabling users to treat multiple spaces in succession with a single base unit.

HaloFogger® EXT

The HaloFogger EXT provides the same flexible nozzle positioning capability as the FLX but with lower fluid output to treat a range of smaller spaces, from emergency vehicles to biosafety cabinets. Like the FLX, the nozzle assembly is detachable and additional assemblies can be purchased to facilitate rapid treatment. Learn More

Track your HaloFogger’s treatment cycles with time-stamped, recorded data logging on your Apple® or Android® Device. This data logging capability features an integrated Bluetooth device with a “real time” clock and sufficient memory to record 30,000 run cycles. The integrated logger automatically stores a dated record of the duration of each HaloFogger dispensing run and the total lifetime hours a HaloFogger has operated. The HaloLog Data Logging feature comes standard on all HaloFoggers.

HaloPortal™ Permanent Thru-the-Wall Remote Nozzle Connection

For spaces that are treated frequently and in environments with multiple separate rooms, the HaloPortal is a permanently installed disinfectant solution that offers great advantages in speed and repeatable efficacy. With the HaloFogger outside of the treatment room, a user can easily join a hose assembly to the HaloPortal and instantly connect to a wall-mounted nozzle assembly inside the room to deliver HaloMist™ Disinfectant. Once dispensing is completed, the detachable hose assembly is disconnected and the HaloFogger can be relocated to a new site without removing the sealed barrier or entering the room requiring full PPE.


  • Operation from outside the room allows rapid treatment cycles without entering the room.
  • Set up time is minimized.
  • Using a single HaloFogger to treat multiple rooms is more cost effective.

HaloShield® Reusable Vent and Smoke Detector Covers

HaloShield reusable vent cover and smoke detector covers help make room preparation for fogging treatment faster and easier. Constructed from lightweight plastic and closed-cell foam, HaloShield installs quickly, effectively covering most standard sized ceiling ventilation and smoke detector locations. The ZipPole® extendable handle provides secure installation of the covers from the floor, with no ladder required. When you’re ready to re-occupy the room, simply lower the HaloShield, disconnect from the ZipPole and store for your next use.

HaloSwitch™ Universal Power Switch

The HaloSwtich™ is an integral component of the Halo Disinfection System that controls operation of the HaloFogger® and an air scrubber (dehumidifier, air handler, etc.). The HaloSwitch will start the scrubbing process automatically, greatly improving room turnaround time. Built with universal receptacles, the HaloSwitch is a dual voltage device that will work with either 120V/60Hz or 220V/50Hz and accept a wide variety of country specific power plugs.

Chemical Indicator H2O2 Strip Tests

Chemical Indicator strips are a simple, effective and reliable method for verifying coverage of the disinfecting mist dispensed by a HaloFogger®. Positioned throughout a room prior to treatment (a minimum of four is recommended, one in each corner of the room), the pad on the strip’s end will change from white to black in the presence of high levels of hydrogen peroxide (70ppm or higher). Position strips wherever you need for positive proof that the hydrogen peroxide disinfectant has reached—and disinfected—that surface.

A Superior Standard for Whole Room Disinfection

The Halo Disinfection System® leads the industry in surface coverage and effectiveness, helping healthcare, long term care, athletic and educational facilities raise their standards for whole room disinfection. Delivering the highest caliber disinfectant solution on the market today, it is proven to kill 99.9999% of C. difficile spores in healthcare settings. Pairing its industry-leading effectiveness with ease of use and a low cost of operation, the Halo Disinfection System® delivers value that is unmatched by other chemical or UV-based whole room disinfection offerings.
