We wanted extra filters for our rooftop air conditioners so that we could install them while the original ones were drying. These fit perfectly and the price that we paid was great! So glad that we got them.
I ordered a pair of filters and they came very quickly in regular mail. By having two, I can wash one while the other is in the AC. I live in Texas, where the drought has made things a bit dusty, so changing the air filter often lets us keep the cool air flowing.
