Just trying product out but was impressed with the sturdiness of the box they arrived in; the furnace filters were well protected.

12 x 12's are hard to find at my local hardware stores, I was cutting a 12 x 24 in half which worked, but these are much better. Also, this has to be the quickest delivery I ever had from Amazon, on my doorstep in 4 hours, no joke.
