Filter Size Formula:
| From: | To: |
Pool filter size refers to the surface area of the filter media required to effectively clean a swimming pool's water. Proper filter sizing ensures efficient water circulation and maintains optimal water quality by removing contaminants and debris.
The calculator uses the filter size formula:
Where:
Explanation: The formula calculates the required filter surface area based on pool volume and the desired turnover rate to ensure proper filtration.
Details: Correct filter sizing is essential for maintaining clean, clear pool water. An undersized filter will struggle to keep up with debris, while an oversized filter may be inefficient and costly.
Tips: Enter pool volume in litres and turnover rate in litres per minute per square meter. Both values must be positive numbers for accurate calculation.
Q1: What is the ideal turnover rate for swimming pools?
A: Typical turnover rates range from 30-50 litres/min/m² for residential pools, but may vary based on pool usage and local regulations.
Q2: How do I calculate my pool volume?
A: Pool volume can be calculated using geometric formulas based on pool shape (rectangular, circular, oval) and dimensions, or by consulting pool specifications.
Q3: What factors affect filter size requirements?
A: Pool usage frequency, bather load, environmental factors (trees, debris), and water chemistry all influence filter sizing needs.
Q4: Can I use this calculator for different filter types?
A: Yes, the formula applies to sand filters, cartridge filters, and DE filters, though specific requirements may vary by filter technology.
Q5: How often should pool filters be replaced?
A: Filter media lifespan varies: sand (5-7 years), cartridges (1-2 years), DE grids (annually). Regular maintenance extends filter life.
