Scientific Findings
St. Croix Sensory Inc. – Fecal Malodor Reduction
Ecobreeze was independently tested by St. Croix Sensory, a globally respected lab accredited to ISO/IEC 17025:2005 standards. Using controlled stainless steel chambers and a challenging fecal malodor stronger than typical restroom conditions, Ecobreeze was evaluated over a 4-hour period.
The results were remarkable:
-
With both carbon filter and fragrance, malodor intensity dropped by 89% within 30 minutes, and over 95% for the remainder of the test.
-
Even with carbon filter only, Ecobreeze achieved significant reduction (10.0 to 23.4) in malodor ratings, decreased sulfur/fecal odor character, and improved hedonic tone (odor pleasantness).
-
All findings were statistically significant and conducted per ASTM E1593-13 and CSPA deodorization efficacy protocols.

Urine Malodor & Carbon Filter Efficacy
Odournet UK Ltd, an ISO 17025-accredited sensory consultancy, conducted a rigorous assessment of Ecobreeze’s carbon filter in isolation, with no added fragrance, in chambers simulating stale urine malodor.
The findings:
-
Odour intensity was cut almost in half, dropping from 4.4 (very strong) to 2.3 (weak to distinct) on the VDI 3882 scale.
-
Hedonic tone improved from -2.5 (very unpleasant) to -1.1 (slightly unpleasant), demonstrating a clear improvement in perceived air quality.
-
Odour concentration in treated chambers was below the limit of detection, indicating a significant and quantifiable impact from the carbon filtration alone.
-
Results showed statistically valid differences at a 95% confidence level.

In this study, researchers explored how our activated carbon can be enhanced with silver (Ag), zinc oxide (ZnO), and a combination of both (Ag/ZnO) to create highly effective antimicrobial materials. Through a series of lab tests, the Ag/ZnO hybrid showed the strongest ability to kill bacteria like E. coli and Staphylococcus aureus, requiring the lowest concentration to stop bacterial growth (Table 1S) and producing the largest zones of inhibition (Fig. 6S).
Advanced testing confirmed that the nanomaterials were well-embedded in the activated carbon (Fig. 3S–5S), and time-based experiments revealed that Ag/ZnO-AC eliminated bacteria significantly faster than the other materials (Fig. 8S). Under the microscope, bacteria exposed to the hybrid were visibly damaged after 24 hours (Fig. 9S), showing not just slowed growth but physical destruction.
Compared to similar materials reported in other studies, this combination stands out for its efficiency and strong antimicrobial properties (Table 2S), making it a promising candidate for future health and hygiene applications.
It’s sustainable, safe, and powerful—exactly what we need to deliver cleaner, healthier air in real-world environments.
Impact Assessment
Environmental and Human Health
At Ecobreeze, sustainability and well-being drive every aspect of our innovation. Our patented air filtration and fragrance system is thoughtfully engineered to reduce environmental impact while prioritizing human health. Unlike traditional solutions that depend on aerosols, batteries, or ozone-producing technologies, Ecobreeze operates on a low-voltage, energy-efficient platform using washable filters and eco-friendly coconut-shell activated carbon.
