Ted B Ponte Vedra Beach , FL July 09, 2016 Got message that charcoal filters needed replacement in our microwave oven We ordered four replacement filters from you (two spares for future replacement). They arrived promptly(within 4 days even over 4th of July weekend). The replacement filters did not fit exactly as the original filters but, we got them in.
