What you don't see hurts you!

Germs, bacteria, viruses, mold, and other contaminants can move through occupied spaces without anyone seeing them. That makes the problem easy to ignore until people get sick, odors develop, or testing reveals what was there all along. What You Can't See Still Matters.

Cleaning Is Periodic. Sanitizing Should Be Continous

Cleaning and sanitizing are not the same. While cleaning can include sanitizing, the effects are temporary and have no impact on airborne germs. What happens is air becomes germ-filled as do surfaces. Breathing is continuous, and so should the sanitizing process

CIMR® - the continuous sanitizing solution

Continuous Infectious Microbial Reduction

The CIMR technology is a Military grade system that integrates into the HVAC system or as simple portable units to completely envelope school occupants in classrooms, hallways, gymnasiums, cafeterias, etc. Requiring no ongoing labor or inputs - only O2 and H2O already in the Air - produces no Ozone or other harmful byproducts.

Why CIMR®

How should the air be treated?

Sometimes the Invisible Problem Has a Smell.

Locker rooms combine people, sweat, moisture, equipment, clothing, shared surfaces, and heavy daily use. For years, people have accepted the smell as part of the environment.

But the smell is telling you something.

Then the Smell Goes Away.

When continuous treatment is introduced, odor reduction gives people something they can experience immediately. Odor is not a measurement of germs, but it makes the larger concept easy to understand: the indoor environment can change even when you cannot see it.

They Can Smell the Difference.

The Bigger Opportunity Goes Beyond Odor.

Germs, bacteria, viruses, and other contaminants usually provide no warning at all. That is why the real goal is not simply a better-smelling locker room.

It Is a Healthier Environment for the People Inside.

Indoor Air Is More Than a Health Issue.

The indoor environment can affect attendance, learning, employee performance, operating cost, and the financial performance of the building itself.

Health Has an ROI.

Healthier Students Spend More Time in the Classroom.

Better Environments Support Better Performance.

Research has linked moisture management and proper ventilation to higher academic performance and reduced absenteeism.

In workplace settings, optimized indoor conditions have been shown to improve computer-based task performance and cognitive response times by up to 9%, while reducing sick-building symptoms.

We do not need to claim that CIMR creates every one of those outcomes. The point is simpler: the quality of the occupied environment has measurable value.

The ROI Goes Beyond Fewer Sick Days.

Continuous air treatment can also become part of the building's mechanical and energy strategy. In Harvest's illustrative 100,000-square-foot school model, avoided equipment and energy savings bring the payback to roughly 5.7 years, and in stronger engineer-verified scenarios the avoided mechanical cost can offset the CIMR investment up front.
