I have a 22x52 Coleman power steel pool. My filter needs to be replaced but my problem is, nobody has them in stock and the ones that I can find online are EXTREMELY over priced. I’ve rinsed and cleaned it as much as I’ve could. It’s starting to crack at the top. Is there any other filters that I can use that is equivalent to these filters? The dimension of the filter is 5.6x5.6x10.
