In the early 1960s when forced air furnace filters were becoming more popular, Dundas Jafine began distributing Permanent Air Filters in 5 different sizes. Canadian Tire was the first major customer to take on this product line from Dundas Jafine. Shortly after the introduction of the filter line, Pipe Wrap Insulation was launched as the second product in the HVAC line-up.
The second generation of Jafines, brothers Bernie Jafine and Murray Jafine, purchased the company from their father Carl Jafine and moved the growing wholesale side of the business to a new warehouse location on Ryding Avenue in Toronto, Ontario. With this new larger space, Dundas Jafine added cat litter and wild bird seed to it’s ever expanding line-up of pet products and began supplying these items to many large grocery chains in the metropolitan Toronto area. The retail location remained on Dundas Street with Carl Jafine continuing to manage it.
