5 Common Water Filtration Sizing Mistakes

Many water filtration problems begin with incorrect sizing. A filter may look appropriate based on pipe size or maximum flow, but still perform poorly if the micron rating, solids loading, or pressure conditions were not considered during selection.

Common Mistakes

• Sizing by pipe diameter instead of actual flow rate
• Choosing a micron rating that is too fine
• Ignoring solids loading and debris type
• Overlooking flush water and drain requirements
• Using maximum flow instead of nominal flow for selection

The best way to avoid sizing mistakes is to evaluate the complete system. Flow rate, pressure, debris load, downstream equipment, and maintenance goals should all be reviewed before selecting a filter.
