Dafco Filtration Group was formed in 2005 as a result of merging two leading Canadian air filter companies Dafco Filtration Products and Filtration Group Canada. Dafco Filtration Products was established in 1985. Filtration Group Canada was a subsidiary of Filtration Group (USA), which has over 60 years of history. Combining the two companies has created the largest independently owned Canadian air filter manufacturer. Together, we make the world Safer, Healthier and More Productive.
