Camfil Canada has released a guide on molecular filtration technology designed to eliminate industrial odours at their source. The company’s filtration systems target persistent odour issues in wastewater treatment plants, food processing facilities and manufacturing operations.
The guide examines traditional odour control methods such as masking agents and increased ventilation, noting their temporary results and potential to introduce harmful chemicals or raise energy costs. It presents molecular filtration as an alternative that removes odour-causing molecules from the air through specialized activated carbon and activated alumina media.
“The best solution is to eliminate odours at the source,” says Geordon Hoag, molecular specialist at Camfil Canada. “Molecular filtration is the most proactive, science-backed approach for controlling contamination and odour. It offers the best long-term solution to address the root of the problem and eliminate it at its source rather than relying on ineffective solutions such as masking agents.”
How the technology works
The filtration systems address volatile organic compounds, hydrogen sulfide, ammonia and other gases that traditional air filters and HEPA filters cannot capture. Odour-causing molecules chemically bond with specialized filter media for removal from air streams, according to the company.
The guide references Health Canada’s 2025 guidance on indoor air quality, which notes that odours indicate elevated contaminant levels. Molecular filtration systems can be used in hospitals, laboratories, data centres and cannabis cultivation facilities.
Field results
The guide includes case studies showing the technology’s application. A British Columbia wastewater facility improved sulfur capture and extended filter life by 15 to 25 per cent using Camfil’s CamPure 15 solution, according to the company.
Camfil’s product line includes box-type filters, cylindrical canister filters, panel filters and combination systems that integrate particle filtration with molecular adsorption. The products are tested against ISO and ASHRAE standards, according to the company.
