This filter is made of a new fiber type. When I restarted my system the initial pressure was about 2.5 psi, previously my initial pressure was 7 psi following filter replacement or cleaning. This tells me that more water is able to pass through the media. I will add that my pool is sparkling clean, so the filters are in fact, working. I'll repost when it's time to clean them and report on ease, or difficultly of the process.

Every other year I changed my Pool filters, so this year was the time again, one thing I could tell you that unlike other brands this one does not have any odor or heavy oil-gease all over the place. The workmanship and quality was outstanding , once filter was changed you could easily see the pumps performance going up thus the power usage ( watt/hr) noticeably coming down. Happy with my purchase.

I picked this up for my father as his filter was needing replaced. This filter is both inner and outer and it's clear that the maker is an expert in their field. This particular brand is actually better than the ones he has used in the past. Also, he said that it is considerably less but the performance is almost unmatched. This filter has replaced the Sta Rite 25022-0201S. Super simple to clean and based on these features and facts, I would recommend this to other consumers. :)

HANXER is one of a dozen or so companies in the booming filter aftermarket that is worth looking for. They make products that are just as good--if not better--than the OEM and sell them at a very reasonable price point. That's what we've got here--this is a set with the inner and outer filters to replace the Sta Rite 25022-0201S OEM product that I used to use. They work just as well, are made just as well and fit perfectly. The only difference? They cost significantly less and that is definitely good news. Highly recommended!
