Filters4Life, and I think they were a reasonable price. We notice far less dust. We change them every 3 months, and they are full of dirt.
Hope this helps.

Our filter looks different then what I'm used to up north. It is approximately 19X20 X
4 inches thick. Is that the size of your filter, Larry.
