Shindaiwa EB45 air filter number 70029-82400. We get them in the shop ever now and then but do not have a source for air filters for them. Do not tell me to see my local dealer. All I have to do for that is look in a mirror. The filters are not available from Shindaiwa or any after market I can find. I heard that there was a change over kit for this unit like there is for another Shindaiwa unit but Shindaiwa says there do not know about it.
