Are you in search of the ultimate replacement cartridge filter guide?
If your pump is the heart of the pool system, then your filter is the kidney. Without proper filtration, your pool will become dirty. Although cartridge filters don’t have a lot of internal parts, they still prove to be troublesome for some pool owners. In order to keep your pool healthy, your filter needs to be intact, free from blockage and properly maintained.
If you’re looking for a one-stop shop for pool cartridge filter maintenance, you found it! In this blog article, we discuss the differences between the original OEM cartridge versus a generic brand. We also discuss filter material, the purpose of the cartridge bands, and list other cartridge-related blog posts and videos.
Original (OEM) or Generic Brands
One of the most frequently replaced parts in a cartridge filter is the cartridge itself. What shocks most pool owners is the price of the cartridge. For example, the original, or OEM, cartridge for the Jandy CL580 filter is $141.99. Which brings us to a frequently asked question– are the OEM cartridges worth the price or could you buy a generic brand instead?
I’ll be very forward, the filter material on the OEM cartridges is the best quality. However, in terms of filtering performance, the generic branded cartridge performs the same. And it is a lot easier on the pockets, as well. The generic cartridge for the same CL580 filter is $87.99. That’s a decent fifty bucks you’re saving.
But how good are the generic filters?
It’s true, all generic parts are not equal. However, I must admit, if you properly maintain your filter, the generic cartridges provide the same filtration as OEM. I speak from experience. For years, we’ve carried Unicel, Filbur, Pleatco, and PureLine generic cartridges. Overall, they have all had an excellent success rate. Sure, some pool owners still prefer OEM over generic, however, for the most part, our customers stick to generic filter cartridges.
Band Count
Have you noticed the bands around your cartridge filter? Have you ever wondered what those bands do? What purpose do the bands serve?
The bands around the cartridge prevent the pleats from moving while filtering your pool. As the glue on the bands deteriorates, it compromises the integrity of the pleats. According to pool manufacturers, the bands also help maintain pleat spacing, making filter maintenance a lot easier. So, the more bands the filter has, the sturdier the pleats are. In turn, it helps to extend the longevity of the cartridge.
But, are the bands absolutely necessary?
Our friends at TroubleFreePool.Com argue that your filter cartridges don’t need them. Although they don’t have scientific evidence to support their theory, they believe that the water flows from the outside in.
As a result, the structural support needed is provided by the tube in the middle and not by the bands. In fact, there are instances where pool owners have purposely pulled the bands off of the pleats to determine if it had any effect on the filtering process. According to them, they saw no difference.
Typically, once the bands start to deteriorate, it’s a sign that your cartridge needs replacing. Sure, the inner core is important. If the solid core is perfectly intact, the bands typically don’t really matter. However, if you have a predator filter, for example, which does not have a solid core, then broken bands might cause an issue.
Material
Reemay is the leading manufacturer of the material found on the majority of swimming pool filter cartridges. The material on the cartridge is spun-bound polyester designed to increase surface area in less space for better filtering. It’s also resistant to chemicals and easy to clean.
In most OEM cartridges, the approximate weight of the fabric is 4 0z. You may come across some cartridges that weigh 3 oz., however, they are usually for low flow spa filtration. Like the OEM brand, generic brands like PureLine and Unicel also use a 4 oz fabric. This adds to the effectiveness generic cartridges provide.
Microfiber
To help combat pool bacteria, Pleatco designed a Microban cartridge replacement alternative. Microban is an antimicrobial blend that prevents and slows the growth of harmful microorganisms. The Microban blend is great for keeping bacteria, algae, and mold from sinking their teeth into your cartridges and extending their lifespan and filtering quality.
Microban is a registered product of Pleatco, one of the generic brand filter manufacturers. This only proves our point, generic brand cartridges perform the same as OEM ones.
The amount of chlorine or other sanitation chemicals required to keep your water clear remains the same. Microban material prevents the growth of those nasty slimy things on the cartridges themselves, but it does not prevent their spread elsewhere to parts like skimmers or water features.
If you live in an area where winterizing your pool is necessary or your water chemistry is an unmanageable beast then Microban is the solution for you.
