Pack of 3 Donaldson P821575 Primary Air Filters Review

Donaldson P821575 was the primary air filter on my 2018 Exmark Radius X Series w/ Kawasaki FX730V Engine that came from the factory. Fast shipping and OEM Donalson packaging = great buy.

Perfect fit for my New Holland TC33D. The dealer in town is starting to sell Donaldson oil filters so I think it's a good company. I don't farm my tractor so my filters get very dusty in the summer and I only want to blow them out about 10 times. Factory replacements are about $50.

Take a good look inside before installing. Mine had the gum hanging out where it was formed. this stuff could break down easily and the carb wouldn't like that. I removed them to and from the filter easily enough, just glad I looked into the b4 setup - I usually take it out of the box and put it in. Good filter, not that expensive. The Polar Ranger is back in the ranks.

Fits my Briggs 39hp Vanguard. It seems to be as good as any OEM filter I've ever used. Metal outer protection grille, good pleated filter material and good soft rubber end caps. The same filter also fits my 49hp Kubota diesel tractor. So it seems a fairly common size for 2-3 cylinder 39-49 hp petrol or diesel engines that use a cylinder shaped air cleaner.
