School Odor Removal - Treatment

Remove school smells, classroom and laboratory odors at their source with ozone.

img-school.jpgThe OdorFree is an excellent school odor eliminator that will remove school odors and also kill microorganisms such as mold and mildew. This results in a fresh smelling facility and a much better learning environment.

Schools and classrooms develop odors as a result of being used for extended periods by a variety of occupants. Even after rooms have been cleaned by the janitorial staff, stubborn odors can linger and be difficult to remove. A residual odor can call into question whether the room has been properly cleaned by staff.

+How to Treat School Odors+

Solution: The best way to eliminate these odors is to run the OdorFree unit at a high level while the facility is vacant. Let the last person who leaves at night turn the unit on and allow the OdorFree to spend several hours oxidizing the odors and reducing micro organism count. The unit should be turned off a couple of hours before the facility re-opens. As a result, both students and faculty will enjoy a fresh smelling facility.

Note: Some rooms have their own separate A/C unit. However, if there is central system with a return vent in the room to be treated, it is best to tape the return duct closed with plastic or paper, and and also close the supply vents during treatment. This will keep the O3 inside that particular room for odor elimination and not let it be circulated into other rooms.

The O3 creates a clean, sanitizing smell which dissipates within about an hour. There is no need to mask odors with perfume like deodorizers, which some people find objectionable and others may be allergic to.

Recommended Model for School Odor Removal

The Villa 1000 is by far the most popular model for school odor removal. One reason is the convenience of the 1 to 12 hour timer that can be set to operate while the facility is closed. It will eliminate school odors in large size spaces but can also be used to treat smaller spaces as well. This model is designed for spaces that are unoccupied for several hours or longer such as Classrooms, Cafeterias, Lounges, Laboratories and other well used areas.

The Villa 1000 has a variable ozone output control that will cover up to 4000 sq ft and a timer that can be set from 1 to 12 hours to automatically turn the unit off when the sanitizing is completed. In addition, a "Hold" selection on the timer allows for extended treatment (until it is manually turned off) in order to eliminate more deeply ingrained odors. This unit can also be used for smaller spaces if rapid odor removal is needed. More details...

Learn How it Works

I am a realtor and also manage rental property. We purchased the OdorFree to eliminate odors in the condominiums we rent near the University of Tennessee. It is amazing how effective the unit is at getting rid of smoke odor, pet odor, and just about anything else!

I recently sold a 4200 square foot home that had a stale, musty odor that actually came from underneath. All it took was one day in the house and one day in the crawl space, and odor was gone. All things being equal, a property that smells fresh sells a lot faster.

The OdorFree is great for removing odors after a smoker or a tenant with pets leaves us. It normally takes about one day to remove the smoke odor and a little longer to remove the pet smell. We even had a deceased tenant that was not discovered until a week later. After three days of ozone treatment the OdorFree had totally removed all the odors.

Some people fry food or cook with heavy spices that leave a strong odor. The OdorFree totally eliminates them and I am very pleased with the machine. It is so easy to use.
