I went on the Aprilaire website to order a new air filter. I have model 2400. I looked at the upgrade kit and thought it looked like a much better idea and purchase. I watched the video-it looked easy enough. I checked and double checked to be sure that this upgrade kit would be compatible with my model-every source on this site stated it was definitely compatible. I received my kit today-took apart my filter housing, following along with the video, and this upgrade DOES NOT FIT MY FILTER HOUSING UNIT. The grooves in the metal frame of the upgrade kit do not even come close to fitting the inside of my unit. Ugh......frustrated is not even the word to describe how I feel. It was 5:22 CST and I called customer service to find that they are closed until Monday. So the dirty filter goes back in and I guess I now wait.....
