The standard filtration time for hotel swimming pools typically follows best practices to ensure water quality and safety. While specific regulations may vary by country, the general guideline is:

Filtration Time Standards

• 8 to 12 hours per cycle: Most hotel pools require one full turnover (complete filtration of all water) within this period.
• Turnover Rate (water circulation frequency):
  • Public/Hotel Pools: 6–8 hours per cycle
  • Spa/Hot Tubs: 30 minutes to 1 hour per cycle
  • Children’s Pools/Shallow Pools: 2–4 hours per cycle

Factors Affecting Filtration Time

• Pool Size & Volume: Larger pools need longer filtration cycles.
• Bather Load: High-traffic pools (e.g., hotel pools) may require continuous filtration or multiple cycles per day.
• Water Quality & Chemical Levels: Filtration should run longer if contamination or cloudiness occurs.
• Type of Filtration System: Sand filters, cartridge filters, and DE (diatomaceous earth) filters have different efficiencies.

Best Practices for Hotel Pools

• Continuous Filtration: Some high-use hotel pools run filtration 24/7 to maintain water clarity.
• Automation & Monitoring: Use automated sensors to adjust filtration based on real-time water quality.
• Regular Maintenance: Clean filters and backwash sand filters as per manufacturer recommendations.
