Why Filtration Timing Matters

Filtration is essential to keep your hot tub or spa water clean. Running the filter too little allows debris and bacteria to build up. Too much can increase energy costs and wear out the pump.

Standard Filtration Times

For most hot tubs, 4–6 hours per day is ideal. Smaller spas may need less, larger ones more. Use dedicated pumps for filtration whenever possible to maintain constant water flow.

High-Use Adjustments

If your spa is used frequently, run filtration longer. During heavy use or hot weather, increase circulation to prevent cloudy water and chemical imbalance.

Pump Options

Single-speed pumps typically handle filtration for a set number of hours. Bi-speed pumps allow energy savings by running at low speed most of the time and high speed for cleaning cycles. 24/7 circulation pumps provide constant filtering and consistent water quality.

Tips for Best Results

Combine proper filtration with balanced pH, alkalinity, and sanitizer levels. Clean filters regularly and replace them as needed. Monitor water clarity and adjust filtration time based on usage and environmental factors.

Correct filtration timing keeps spa and hot tub water clean, clear, and safe. Adjust daily hours according to usage, pump type, and water conditions. Consistent filtration ensures a relaxing soak every time.
