Why Indoor Air Quality Matters More Than Ever for Canadian Workplaces
Canadian building codes are tightening IAQ requirements. Here is what facility managers need to know about compliance and best practices.
How Data Centres Can Reduce Operational Costs Through Better Air Treatment
Data centres face unique air quality challenges from adjacent landfills, industrial sites, and urban pollution. Here is how NCCO addresses them while cutting HVAC costs.
Activated Carbon vs NCCO: Understanding the Total Cost of Ownership
Activated carbon filters seem cheap upfront but carry hidden replacement, disposal, and labour costs. A TCO analysis reveals the real picture.
The Hidden Cost of Poor Indoor Air Quality in Commercial Buildings
Poor IAQ costs businesses billions annually through lost productivity, increased healthcare expenses, and employee turnover. Here's what facility managers need to know.
Mar 28, 2026NCCO vs Activated Carbon: A Technical Comparison for Facility Managers
A comprehensive technical comparison of NCCO technology versus traditional activated carbon air purification, covering lifespan, efficiency, maintenance costs, and pollutant removal capabilities.
WIPO GREEN Database: NCCO Technology Profile
Official WIPO GREEN technology database listing for NCCO (Nano-Confined Catalytic Oxidation) by RHT Environment Technology. Describes NCCO as a breakthrough air purification technology using nanoscale carriers and specialized catalysts to decompose formaldehyde, VOCs, bacteria, and odor molecules into harmless water and carbon dioxide through a closed-loop adsorption-catalysis-decomposition mechanism — without filter saturation or secondary pollution.
NCCO Effectiveness Against Marijuana Smoke Chemicals and Odour
Published in SN Applied Sciences (2021), this University of British Columbia study evaluates NCCO's effectiveness in eliminating marijuana smoke pollutants. Results show an average 93.4% reduction in THC, CBD, and Cannabinol concentrations after 30 minutes, statistically significant reductions in PM2.5, PM10, and TVOC, and a 55.6% reduction in perceived marijuana odor after 50 minutes — confirmed by 20 human volunteers in a single-blind study.
UBC Research Report: NCCO Technology Comparison Summary
A concise UBC research report comparing three air purification technologies — Ionizer (PCI), Ultraviolet Photocatalytic Oxidation (UV-PCO), and NCCO — in a sealed 1m³ chamber. Testing against ammonia, toluene, and hydrogen sulfide, NCCO demonstrated superior pollutant concentration reduction and odor elimination while keeping ozone levels constant, unlike the other technologies which increased ozone.
