In layman’s terms, a filter is just like the kidney of a swinging pool. It filters out the unwanted nasties and the yard debris, leaving your pool water clean and fresh. Most of the standard residential swinging pools hold water in the capacity 13,500 and 30,000 gallons, which is well within the standard pump(filtration) systems.

Working of Pool Filters

A standard pool pump can pump 60 to 70,000 gallons of water in six to eight years. Hot tubs and small pools need filter cartridges’, made out of corrugated paper or polyester cloth. Majority of the backyard pools, however, go with filter pumps, which employ glass media or sand. 

A sand filter operates by letting the pass through a canister in the pump, which is containing sand. However, most of the smaller particles will easily pass through, leaving all the big problematic particles behind. This is essentially how a pool filtration system works.

The glass filter works very much similar to the sand filter; however, glass can capture particles up to 1/4 size of the sand filters. Thus, it is way more effective. 

After that, water passes through the filter, and the process continues. But, like most things, the filtration ability of pool filters reduces significantly with age. The filter will appear clogged and dirty and often appeal horrible, and the water follows the same suit. So, to avoid this, you’ve to replace the filters immediately. 

How Long do the Cartridge Filters, Sand and Glass Filters Or Pump Filters Last?

You can expect the cartridge filters to be replaced every 1 to 2 years. The sand filters, on the other hand, can function efficiently for 3 to 7 years. A pump system that houses it owns filtration system last between 8 to 15 years, 

Maintaining Your Filters

Even if you take great care of your pool, there are several things you can do to make your pool filter last longer. First, try to use clean water, and don’t forget to rinse the pool when it is empty. Make use of the water clarifiers to lower the clogging’s risk. 

If you’re using a sand/glass-based pump filter, then you should perform the backwashing procedure now and then. On the other hand, for a cartridge filter, make sure you regularly remove and rinse it thoroughly with the help of a hose and hard brush. Do it at least once a week to make your filters functioning optimally. 

When Your Filters Need Replacing

You can visually determine if your pool filters are working properly or not. However, it is highly recommended to replace the cartridge filter well before it’s use-by-date, which is generally 1 to 2 years (depending on the brand). If there is a tear in the filter, replace it right away. 

Frequently, check the pressure of the filter canister, if it’s not at the right level, as this is a sign of clogging. If you see the water flow grinding to a halt, then it’s time you replace the filter. 

Final Verdict

Apart from the pool filter, another key pool accessory is a pool cover or pool enclosure. From protecting your pool from dirt, dust, debris to preventing water-borne illnesses, and saving money on heating water, the benefits make the investment worth it.
