How to Choose the Best Pool Filter Cartridges?

Besides basic specifications such as its dimensions or number of filters per package, there are other important factors related to a pool filter cartridge. You should take into account the features below to ensure the cartridge you get is the best one.

Compatible Models

You should concentrate on the product parameters and description to find out which existing pool filter models this cartridge adapts to since most cartridges are manufactured to be a replacement element.

Many online shopping websites support users by entering the filter model number to make sure the selected cartridge fits. Each pool filter has its specifications, so a brand new cartridge needs to have the same measurement before being installed.

Support Bands

The support bands are responsible for holding the pleats. These pleats on each pool filter cartridge are clearly defined by the wrapped-around bands and evenly separated to allow higher water flow. Its operation time can be quicker.

If a cartridge includes weak support bands, its pleats will likely collapse and result in a significant reduction of the filter’s usable areas. Low-quality bands can also shorten the filter lifespan and increase backpressure for the entire pool filtration system.

Filtration Fabric

REEMAY is a widely applied material to build pool filter cartridges. The reason behind this is as this spun-bonded polyester is a sheet structure with filament fibers that are randomly arranged, thoroughly dispersed & bonded at the junctions.

The filament polyester fibers that are crimped offers high conformability along with softness and enhanced porosity for this pool filter cartridge. Whereas, the straightly arranged fibers provides a tighter structure that is stiffer with much better assistance.

Trilobal fibers of the REEMAY polyester can deliver better filtration surface area up to 21-40% of efficiency if compared to other competing materials. Furthermore, this trilobal shape grabs particles without the pressure drop penalty, which is less filter cleaning.

How to Replace Pool Filter Cartridges?

In general, it is not difficult to replace most pool filter cartridges available on the market on your own at home. I would like to introduce the simple steps to support you with how to properly replace a damaged pool filter cartridges with a brand new one.

You should have either cut out the old filter or turn off the electricity running to the pump motor in case it turns on all of a sudden. The cartridge should be taken out of the housing to prevent unwanted damages during the process and put its top back on.

It is crucial to determine precisely the water flow through the pool pump and this filter cartridge. Put some silicone into the filter housing threads then use your finger to spin around. Next up is to wrap the plumber’s tape around it in a counterclockwise direction.

On the threaded side of the coupling should be wrapped with tape 7-10 times. You might want to install these threaded couplings on both opening sides of the filter housing. I would recommend using pliers to have it tightened but do not over-tighten.

Subsequently, the housing can be positioned where you prefer. The input and output ports have to be aligned in the proper direction so as the latter one can go to the pool pipe. 6-inch pipe extension from each outlet is ideal for more room on both sides.

The cut pipe section should fit the filter output port and be extended to the pipe that goes to your pool. After cutting it down to size, you should check for the length to see whether it has been a suitable measurement or not and apply cement into the coupling.

Following, line up the filter output pipe with the pool pipe. Use a marker to mark below this pipe and cut it off for it to butt up against the pipe. Make sure the pipe is straight with a corner ruler. A hacksaw blade should cut the underside of the pipe.

Remember to clean both sides of the 90° coupling. After that, I advise getting a file or sandpaper to rub the pipe edges a little bit. You would not want to have these units misaligned after gluing them to each other, so it is best to test the fitting in advance carefully.

The PVC cleaner is an excellent choice to brush the pipe and coupling. When the cleaner has completely dried up, the pipe and the coupling will be cemented together. This is the last step for completing the output connection from this pool filter to the pool pipe.

Then, it is time to connect the pump pipe to where the filter housing intakes water. The pipe section required after cutting is 6-8 inches, then cement it into the threaded coupling that you have already positioned previously. Place this 90° coupling at the end.

The next piece of pipe that needs to be cut should respond to these requirements: when it sits vertically inside the coupling, it has to extend at least 12-15 inches above the motor and set into the coupling. Cement the assembly of this straight intake pipe.

When you go to the pump motor, cut down the existing pipe that extends 4-6 inches from above the fitting. Set up the 90° coupling into this pipe without cement. The next cut pipe section is the one that fits the coupling and extends to the intake pipe filter.

Again, make use of a corner ruler to ensure the top pipe is straight. Mark on the intake pipe and cut it to size. There should be no cement when you put the coupling in. If everything lines up, you can now cement the entire Shebang together.

A couple of hours later, when the cement has settled down, you should open the filter housing and check for any leftover debris or work parts that might fall inside. Lastly, put the filter cartridge back in, turn on the pump, and have it worked on testing for leaks.
