Pool Filter Cartridges Vs Other Filter Media


Your swimming pool pump circulates water through your filter system, which catches the dirt that cannot be broken down entirely by the pool chemicals. Aside from pool filter cartridges, there are several other filter media types, including sand and glass filters.

Cartridge filters are the go-to options for many small pool owners because they are cheaper, wonderfully effective at keeping water clean and easy to use and clean. They are especially popular for use in hot tubs and spas.

We offer a selection of pool and spa filter cartridges from leading brands you can rely on, including Bestway filters suitable for your above ground pool. 


How to Clean a Pool Filter Cartridge


Pool filter cartridges are tall, barrel-like cylinders made from corrugated paper or polyester cloth. They are easy to remove from your pump and filter system, which makes cleaning them a simple process.

If you’re doing a quick clean, you can rinse the garden with water, running water over each of the pleats. If a deep clean is required, you can use filter cartridge cleaner.

You should clean your pool or spa filter at least once a month, if not more and certainly after heavy usage, to ensure it keeps performing well for as long as possible.

How Often Should You Change Pool Filter Cartridges?


How often you’ll need to clean or replace your filter will depend on a number of things:

  • - How often your pool is used.
  • - How big the filter is.
  • - How susceptible your pool is to excess dirt.


At a certain point, simply cleaning your filter cartridge may not be enough, and you’ll need to replace it. Replacement will be necessary around every 2-4 years.

Here’s what to look out for if you think it’s time to replace your filter:

  • - Past its predicted lifespan – Once your pool filter cartridge is past its use-by date, it’s likely a good idea to buy a new one.
  • - The cartridge appears crushed or deformed.
  • - High pressure on the pump system even after a clean.
  • - Worn fabric or tears in the cartridge.
  • - Cracks on the plastic casing.
