How many air filters do I get in a case?

I called the HVAC corporation Last monthbecause I wanted to buy a case of air filters for our oil furnace plus unit.

Before I bought the air filters, I wanted to think how many air filters were in the case.

I understood I was getting a great price by buying them by the case, but I had to make sure I had some locale to store them. The HVAC tech assured me I could store them in the garage or in the basement. As long as they didn’t get wet, they would be fine. It wasn’t whether they would get wet, but if I had the room for many cases of air filters. He said the air filters had twelve in a box. At least now I had some plan how much room I needed for the air filters. I started looking in the garage plus the shed, hoping to find a shelf that would hold many cases of air filters. I found a shelf in the basement where I could put the oil furnace air filters, but I couldn’t fit the A/C component air filters there. Then I realized I could put them in the laundry room. The laundry room was in the mudroom, plus the component was right outside the mudroom. At least I had solved the concern with where I was going to put the air filters. Now I just had to m tell the HVAC tech what kind of air filters I needed. I would need to check the outdated air filters plus provide him the numbers that were on them.
