Pool Filter Cycle

A filter cycle is the length of time a pool filter runs before requiring cleaning or backwashing.

Understanding the Filter Cycle

The filter cycle refers to the period a pool's filtration system operates before it needs cleaning or backwashing. The efficiency of a filter cycle depends on factors such as bather load, water clarity, and the type of filter media used.

What Determines a Filter Cycle?

  • The type of filter being used, such as sand, cartridge, or DE.
  • The bather load and overall pool usage.
  • The turnover rate and efficiency of circulation.

Signs a Filter Needs Cleaning

  • Increased pressure on the pressure gauge, indicating reduced water flow.
  • Cloudy water due to ineffective filtration.
  • Weak return jet flow, suggesting clogged filter media.

Related Terms

  • Backwashing – The process of cleaning a filter by reversing the flow of water.
  • Filter Media – The material inside a filter (sand, DE, or cartridge) that captures debris.
  • Pressure Gauge – A device used to monitor filter pressure and determine when cleaning is necessary.
