Professional Recommendations

• Hayward Pool Products, a major manufacturer of pool equipment recommends that a pool filter run 10 to 12 hours per day during the peak season when the weather is hot and the pool receives a lot of use. During cooler weather, such as early and late in the season, 4 to 6 hours per day should suffice.
  
  

Energy Considerations

• In an effort to conserve energy, the U.S. Department of Energy suggests reducing filtration time to 6 hours per day. If the water remains cloudy after that period of time, they recommend increasing the duration by 1/2-hour increments until the water clears.
  
  

Bottom Line

• Since pool cleanliness depends upon numerous factors, such as bather load, pool size, pump horsepower and filter type, only you can decide the appropriate filtering needs of your pool. Following the recommendations of the Department of Energy allows you to determine the minimum daily filtering time required to keep your pool clean. Doing so may save you money and conserve energy.
