Pool and Spa Applications
The unique structure of point-bonded fabric promotes the formation of a filter cake in pool and spa applications. Additionally, it increases filtration efficiency over time. Moreover, the consistent patterned welds facilitate easier cleaning by preventing debris from becoming deeply embedded in the media. This stability and flexibility make point-bonded filtration media an effective and user-friendly choice for a range of filtration needs.

Modern Polyester Spunbonded Filtration Media
Point bonding produces modern polyester spunbonded filtration media. Furthermore, it offers significant benefits for both industrial and consumer applications. Additionally, this technique continues fibers are rapidly spun from spinnerets and interlocking to form a web-like structure.
The web secures a calendar roll with patterned high spots and creates distinctive dimples in the fabric. Furthermore, this process not only locks fibers at specific points but also allows for fiber movement between the welds. Therefore, it enhancse the media's ability to capture various particle sizes.

I ran a search using bing to try and find someone that carried this pool filter and at a better price than what I had seen in other searches. This particular filter was hard to find. This was the most reasonable price though, so I purchased it. The purchase was trouble-free and the product was delivered quickly.
