FAQs 

How often should I replace a pool filter cartridge?

Pool filter cartridges usually need to be replaced every 3 to 5 years. However, this timeframe can vary. The actual lifespan of your filter cartridge really depends on factors like pool usage, bather load and the amount of debris it processes. It is important to monitor the performance of your filter regularly, as this will be the most accurate indicator of when a replacement is truly needed, potentially extending or shortening its service life beyond the typical range.

What is the life expectancy of a pool cartridge?

A pool cartridge filter typically lasts three to five years. Its longevity is influenced by things like pool usage, water chemistry and even the level of cleaning.

What is the best way to clean a pool cartridge filter?

Cleaning a pool cartridge filter is a three-step process: 

  1. Prepare the system and remove the filter
  2. Clean the cartridges
  3. Reassemble and restart the system

Regular cleaning is really important for maintaining water clarity and filtration efficiency.

How often should you clean your pool cartridge?

You should clean your pool filter cartridge when its pressure gauge reads 8-10 PSI higher than its normal clean operating pressure. As a general guideline, a routine rinse is recommended every 4-6 weeks during active pool season, too.

Do cartridge pool filters need backwash?

No, cartridge pool filters generally do not require backwashing. Unlike sand or diatomaceous earth (DE) filters, cartridge filters are maintained through a manual cleaning process.

How do you know if your pool cartridge filter is bad?

Identifying a failing pool cartridge filter is important for maintaining water quality and circulation. Look for these key signs:

  • Decreased Water Flow: A significant reduction in water returning to the pool indicates the filter is struggling to process water efficiently.
  • Poor Pool Water Clarity: If your pool water remains cloudy or murky despite proper chemical balance, the filter may no longer be effectively trapping contaminants.
  • Higher Pressure Readings: An elevated pressure gauge reading on your filter system, especially after cleaning, often signifies a clogged or damaged cartridge impeding water flow.
  • Visible Damage to the Cartridge: Tears, rips, crushed pleats or a deteriorating end cap on the filter cartridge are clear indicators it needs immediate replacement.
  • Age of the Cartridge: Most pool cartridge filters have an effective lifespan of 1-3 years. If your cartridge is older than one year, even without obvious physical damage, its filtration efficiency may be significantly reduced.
