为泳池选择正确的过滤器尺寸。根据水量和循环时间计算砂缸、DE 或滤芯过滤器的所需面积。
The filter must be large enough to pass the pool's full turnover flow without exceeding its maximum design flux. Residential standards: sand filters up to 15 GPM/sq ft, DE up to 2 GPM/sq ft, cartridges up to 0.375 GPM/sq ft.
Mode A (Size a Filter): enter pool volume and desired turnover time. The calculator outputs the required GPM and the minimum filter area for each media type — helpful when buying new equipment.
Mode B (Check My Filter): enter your filter type and media area to see its max flow and whether it can turn over your pool in a reasonable time. Undersized filters force longer run times or push water through too fast, hurting filtration.
是的。较大的过滤器有更多的表面积，意味着清洗间隔更长，并且对泵的阻力更小，提升整个系统的效率。
三种类型是：沙缸（最易使用）、滤芯式（无需反洗）和硅藻土（D.E.，提供最细致的过滤）。
用您的泳池总容量除以所需的循环时间（通常8小时），即可得出过滤器必须处理的最低GPM（每分钟加仑数）。
