Measuring a pool filter involves determining its outer diameter and inside diameter to ensure you get the correct replacement size.
To accurately measure the diameter of your pool filter cartridge, you need to take two primary measurements as outlined in the reference provided: the outer diameter and the inside diameter. These dimensions are crucial for finding a compatible replacement filter.
Here is a simple guide on how to measure your pool filter:
-
Measure the Outer Diameter:
- Place the filter on a flat surface.
- Using a measuring tape or ruler, measure straight across the widest part of the filter.
- Measure from the outer edge on one side all the way to the outer edge on the opposite side.
- You can take this measurement from the top or the bottom of the filter. This gives you the overall width of the filter cartridge.
-
Measure the Inside Diameter:
- Next, measure the opening that runs through the center of the filter.
- Measure straight across this central opening from one inside edge to the other.
- If the filter has threads in the center opening, measure the diameter of the opening across the inside edges of the threads.
- This measurement is important for how the filter fits onto the central pipe or standpipe in your filter housing.
Taking both the outer and inside diameter measurements ensures you have the key dimensions needed when looking for a replacement pool filter cartridge.
Here's a summary of the measurements:
| Measurement | Description |
|---|---|
| Outer Diameter | Distance across the filter from left outer edge to right outer edge (top/bottom). |
| Inside Diameter | Distance across the opening through the middle or inside edges of threads. |
Always measure precisely to the nearest 1/16th of an inch or millimeter to find the best filter match.
