I wanted to like these, but the size it states is too big for the opening. I don't understand how that is happening, considering I bought the correct size.

I noticed how well the filters were made when I had to trim them to fit my return. Can you please stock 12x30x1 so I don't have to cut off two inches from the 14?

I have been using this product for years. Since I have a dog, this product has kept our allergy’s at bay. Also, since I live in a rural area, dust is non existent. Would not use anything else
