The filters just disappeared

I thought I had a full box of air filters for my a/c unit.

I was sure I had them in the garage, but when I headed out to get them, the box was empty. At first I thought that someone had gone into my garage and maybe stolen the air filters, but that made little sense. I then wondered if maybe I had used the a/c air filters in the gas furnace. I wasn’t sure if they would even fit in the gas furnace. I knew I had to have used all the air filters. Maybe I just never thought about it being the last one I had left. So, I called the Heating and A/C supplier and asked if they had a case of air filters for both the gas furnace and AC unit. I knew I would use them for the gas furnace soon. They told me to go to the local home center since they didn’t have air filters in stock. I got to the home center, however I had forgotten the style and air filter number with me. I knew what they looked like, and I was sure I could pick them out when I saw them. I took a box of air filters home and I opened it up. After pulling one out, I knew it wasn’t the right air filter. I tried to make it fit, but it wouldn’t no matter how hard I tried. I ended up taking the air filters back to the home center, but they would not take them back since I had broken one trying to put it into the A/C unit. Next time, I’ve got to find the right air filters, because this venture cost me too much money. Air filters aren’t cheap.
