offering far greater volume dirt holding capacity than other filtration fabrics. With reduced pore size distribution, the fabric provides impressive turbidity reduction via unique cross filtration flow, easily and efficiently capturing dirt particles to achieve a deeper level of cleanliness and clarity than ever before.

PLEATS & BANDS

Every filter cartridge has a certain standardized square footage of filtration fabric that is pleated to a specific pleat count and is held together around the core by the cartridge band. Pleating is extremely important as it creates peaks and troughs in the fabric that allows the water to flow across the surface and through the fabric to capture debris and dirt particles.

Most pool cartridges are held together with 3 or 4 bands that are placed at specific intervals around the cartridge to keep the pleats even under pressure in the tank, and allow for cleaning.

With most standard cartridges the bands can stretch or even break under pressure, allowing the pleats to flap apart or compress together. Bands can also be difficult for maintenance as dirt particles can get lodged where the bands are attached to the filtration fabric making cleaning more difficult.

In recent years, new manufacturing techniques have emerged to optimize the filtration fabric surface. Pleatco has developed an exclusive technology that creates the first “no band cartridges” by using a unique pleating system that holds the pleats in place from the inside, negating the need for the bands on the outside. This Pleatco PurePleat ™ patent pending manufacturing process has pushed the boundaries and delivered the most high-performance filter cartridge in the world. The company has taken the bold step to ensure the service industry and bricks and mortar stores and distributors benefit from this superior product. Marketed as Pleatco Advanced ULTRA this top-end filter cartridge range is not available on the Internet. Tip: When deciding on a replacement look at how well the bands are attached to the cartridge or better still the cartridges that have no bands at all.

END CAPS

Finally end caps hold the whole cartridge together. Generally made with high-density Polyurethane, end caps ensure the pleats stay in equal distance top and bottom and act as a seal within the filtration tank when it comes to pools. It’s important to note that quality cartridges are made with the highest-grade polyurethane. Substandard cartridges end caps tend to crack under pressure and provide a very short lifespan for the product.

In the case of spas, the end cap may also include a thread at one end that screws the cartridges into the filtration bay of the spa. A big note: End caps from reputable filter cartridge manufactures will have the company brand and part number on them.

Beware of cheap imitations that disguise themselves as the original article. You can tell this by noting if the end cap has been beveled with a brand and part number or not!

So, in summary please realize that all replacement filter cartridges are not the same. Superior cartridges provide the highest cleaning performance and are easier to maintain. While slightly more expensive they are the most reliable.

We always say your pool is like a Ferrari. You wouldn’t put a KIA filter in it just to save a few bucks because that would compromise performance, quality, and reliability.

Be sure to look for top brand filter cartridges, that are made to the highest standard, have the latest filtration technology, and are backed and guaranteed by highly reputable USA firms like Pleatco.
