About LD Filtration

LD Filtration is Western Canada’s premier source for HVAC filtration and mobile engine filtration. The company was formed in 1993 by Dan Linehan, an entrepreneur who bought the filter company where he worked.

Under his leadership the company has boosted sales over 1,400 percent, serving heavy industry in Alberta, Northwest Territories and British Columbia. Business has expanded to include HVAC air filtration products that improve indoor air quality for buildings from hospitals to high-rises and factories to tech centers.

Formerly L&D Distributors, the company acquired Corona Supplies of Calgary in 2002. Calgary’s filtration pros operate under the LD Filtration banner and stock significant inventory to best serve Southern Alberta clients.
