    Hey guys just checking to see if it is ok to clean your air filters and reuse them. Or should you dispose of your old one and buy new. Thanks

    I buy New and use New filters. I'd rather pinch a penny someplace else.:D

    I blow mine out a few times then replace them(Exmark and Walker). I have a compressor with a small air nozzle. I can just about make them look brand new just by blowing them out.

    If you are talking about the foam wrap, or pre filter, these are washable & reusable (dish soap & water). You shouldn't blow compressed air into the actual filter. This is because there are Micro Filaments in there that are fragile (you can't see them). Using compressed air on these comprimises the integrity of the filtering, thereby allowing more dirt particles to pass through than they are designed to keep out. Bad for the engine.

    I clean the prefilter every week, and replace the filter with a new unit every month during mowing season. Better new air filter than a new engine.

    I blow out my air filters a couple of times, and have a diesel yanmar with a 2 filter system. I am talking about the primary filter. I only blow from the inside - out as you can disrupt the filters efficiency by blasting it off from the outside - creating channels for dust to go in later. Also - I do not use anything but a gentle air flow. I remove most of the dust by gentle tapping on the cement driveway.

    I'm with brl on tis one. I worked in the auto business fo 15 years. Blowing out the filter opens up the pores in the filter material and allows more dirt past thefilter.

    I, too, learned years ago that you never, ever, use compressed air on pleated paper elements. A light tap on the bench to loosen dirt, but you destroy their filtering ability by blowing them out.

    Just curious to know if you guys are oiling your foam prefilters - I do, and they get rather dirty in 10 hours but the paper filter has no visible dust on it - a good thing, I guess! So, I haven't done anything to the paper filter in 100 hours but regularly clean and oil the foam prefilter.

    Tap them out and then blow with the blower at 1/2 throttle to blow away what I loosened up. Replace as needed.
