Donaldson Blue air filters for Fleetguard® Direct Flow™ air cleaners were tested head-to-head against OEM filters. Both sets of filters were bombarded with dust, vibrated and shaken, and then carefully examined.

As expected when tested per ISO 5011, Donaldson Blue filters perform well on the important characteristics of dust capture — where they reached 99.97% overall efficiency — and capacity (filter life). It’s when we compare sealing technology that Donaldson filters really stand out.

Donaldson filters deliver 50% more sealing area & 2x more gasket compression than Fleetguard® Direct Flow™ Air filters.
