FAQs 

How do you know when your pool filter needs to be replaced?

The biggest indicator that a pool filter cartridge requires replacement is any signs of structural failure, which is determined through a physical, visual inspection.

A filter cartridge is considered worn out and should be replaced if you observe the following key signs of cracking and deformed ends. 

Can you clean a pool filter instead of replacing it?

Yes, you can and absolutely should clean a pool filter regularly. Cleaning is mandatory maintenance for all pool filter types (cartridge, sand, and Diatomaceous Earth/DE) and is really important for maintaining water quality and maximizing the filter's lifespan. Replacement of the entire filter or the filter media/cartridges is only necessary when the component is irreparably damaged or has reached the end of its typical operational life.

What is the average lifespan of a pool filter?

The average lifespan of a residential pool filter typically ranges from 5 to 10 years. This is not fixed and is heavily influenced by two primary factors: the specific type of filter used (cartridge, sand, or D.E.) and the consistency and quality of preventative maintenance it receives.

How often should pool filters be cleaned?

The frequency of cleaning or backwashing a pool filter is dependent on the internal pressure of the system, not by a set time schedule (such as weekly or monthly).

You should clean or backwash your pool filter whenever the pressure gauge on the filter tank registers 8 to 10 PSI (pounds per square inch) above its normal, clean operating pressure.

How much should it cost to replace a pool filter?

The cost to replace an entire pool filter system, including the unit and professional installation, typically ranges from $250 to over $1,200, depending primarily on the type of filter chosen.

The price fluctuation is driven by the technology used, with cartridge filters being the most economical option for total replacement and Diatomaceous Earth (DE) filters representing the premium end.
