I got these because they looked pretty good and were a bit cheaper than the ones sold elsewhere and all I can say is you get what you pay for. These things didn't last 3 months and my spa had more floating debris than ever before. Within a month one of the two filters I bought had cracked, and within 3 months one had the threads that hold it in place break off so it was completely useless. So I went directly to Bullfrog and bought their newly redesigned filters which are awesome. Seriously, it is a great redesign they did where the center cap stays in the tub and just the outer filter housing is taken out for cleaning. Much easier to clean and a lot more solid than the ones I bought here.

Anatomy of a Pleatco Filter Cartridge for Bullfrog Spas
Filter Cartridges are a system. This system includes CORES, MEDIA (Filtration Fabric), BANDS, and END CAPS. Pleatco does research and works with the best companies in the world to design the strongest and most efficient filters. A properly designed core MAXIMIZES the filtration area, increases flow, and creates uniform flow distribution through the entire cartridge increasing its life and the cleanliness of your water.
FREE FLOW CORES
Pleatco FREE FLOW CORES are superior as they are designed to significantly enhance the filtration process over any other competitive product. Pleatco’s cores are ‘engineered’ as opposed to all other cartridge manufacturers who simply use PVC pipe with holes drilled in them. Pleatco FREE FLOW CORES deliver better water flow rates, giving enhanced filtration and reducing wear and tear on the pump and therefore, also uses less energy.
The MEDIA serves as the filtration surface. Pleatco only uses the highest quality spun bonded polyester material for all Pleatco Filter Cartridges.
The number of PLEATS and the total amount of media used in a filter cartridge impacts the quality and performance of the filtration. The amount of media in a Pleatco Filter Cartridge meets, or in many cases, exceeds the original equipment specifications providing quality performance and extends the life of the product.
The BANDS keep the pleats separated helping water to easily flow through the filter. Pleatco’s bands are the strongest in the market and ensure that the pleats are separated even under great stress.
The END CAPS help to provide structural support and increase filter cartridge durability. Unlike any other filter cartridge manufactured for the pool & spa marketplace, Pleatco Filter Cartridges have end caps that are 100% Antimicrobial. This enables Pleatco Filter Cartridges to be more effective in prohibiting the growth of mold, and reducing mildew and odor causing bacteria.
