Donaldson Filters

Our company founder, Frank Donaldson, designed and built the first air cleaner and filter for a heavy duty engine in 1915. Since then, nearly every significant innovation in air cleaner technology has been led by Donaldson. Today our air filters are setting new standards in filtration quality, coverage and performance – with filters that fit our own air cleaners and those manufactured by others. When you choose Donaldson air filters, you get performance that's anything but standard.

We offer a wide range of air filters for every need

  • PowerCore® Filters 
    • Evolving emissions regulations (and greater emissions system space claim) has driven the need for increasingly smaller and lighter air cleaners.
    • Much more compact at a given performance than other filters
    • Straight-through airflow design delivers better overall efficiency and better dust-holding capacity than other filter configurations
    • Invented by Donaldson
  • RadialSeal™ Filters
    • Create a superior seal and vibration resistant interface between the air cleaner and the filter
    • This reliable seal helps to protect engines in extreme operating conditions
    • Invented by Donaldson more than 25 years ago
    • Offering replacement filters for Donaldson air cleaners – and for many competitive air cleaners
  • Axial Seal Filters
    • Traditional filter design with a gasket on the end of the filter that gets compressed against the housing to create a tight seal
    • Our filters have a strong, pliable gasket that ensures a leak-free seal when properly installed
    • Our gaskets won't harden or deteriorate over the life of the filter


  • On-road trucks
  • Off-road trucks and equipment


  • Donaldson branded filters are designed specifically to give you effective, consistent performance over the life of your engine
  • The company that invented air filters for heavy-duty engines to deliver the broadest vehicle and equipment coverage, the most consistent quality and the best overall performance


  • Heavy duty liners – corrosion resistant, coated steel liners support the media during operation and help maximize airflow
  • Pleatloc™ media spacing – ensures uniform pleat spacing, which keeps filter media from bunching and promotes longer service life
  • Beading – applied to filter liners, beading is designed to stabilize media and prevent pleat tip wear

Available Media Type

  • Cellulose – standard media used in the majority of air filter applications
  • Flame retardant and vibration resistant cellulose media variations available to meet specialty engine applications requirements
