How to Measure Pool Filter Cartridge Size and Choose the Right Replacement

If you have a pool at home, you know how important it is to keep the water clean and clear. The pool filter cartridge is an essential component of your pool’s filtration system, as it ensures that the water is free of debris and harmful contaminants. However, over time, pool filter cartridges wear out and need to be replaced. To do this, it is important to understand how to measure pool filter cartridge size to ensure you choose the right replacement.

This article will provide you with a step-by-step guide on how to measure pool filter cartridge size, so you can confidently purchase the correct replacement filter for your pool.

Why is it important to measure pool filter cartridge size?

The size of your pool filter cartridge is critical to the effectiveness of your pool’s filtration system. If you choose the wrong size, it could lead to poor water quality, reduced performance, and increased maintenance costs.

Step-by-step guide to measure pool filter cartridge size

To accurately measure your pool filter cartridge size, follow these steps:

1. Identify your pool filter model

To find the right replacement filter cartridge, it is essential to know your pool filter model number. If you don’t have the model number written down, check your pool owner’s manual, reach out to your pool equipment provider, or search online to get it.

2. Measure the length of the cartridge

Use a tape measure to take the length of the existing pool filter cartridge. Start measuring from one end of the filter cartridge, and along the central pipe, go straight to the other side. This measurement should be the entire length of the cartridge, including the end caps or handles.

3. Measure the diameter of the cartridge

Take the diameter measurement across the widest part of the pool filter cartridge, including the end caps, for accuracy. Use a tape measure to measure its width in inches or millimeters.

4. Check any unique features to match replacement cartridges

In some cases, pool filter cartridges may have specific spring orientations or odd-shaped handles, tabs or extensions. Ensure you take note of all these unique features when looking for a replacement filter. It is essential to match these features when purchasing a replacement cartridge, so you don't end up with something that won't fit.

5. Determine the cartridge's square footage

The square footage of a pool filter cartridge shows the area of its pleated material, and it determines its filtering capacity. Typically, it is written on the cartridge, or you can refer to your pool filter manual to determine the square footage.

Selecting the right pool filter cartridge replacement

Once you have all the measurements needed to choose a replacement cartridge for your pool, you can start searching. Filter cartridges come in a variety of sizes and types, so ensure you match your replacement cartridge to your pool filter model, ensuring all the measurements align with the original filter cartridge.

Consider the following factors when selecting a replacement cartridge:

- Filtration performance

- Durability

- Fit to equipment

- Maintenance

- Cost

The bottom line

With the step-by-step guide listed above, you can measure pool filter cartridge size and choose a replacement cartridge that has the same dimensions with the original cartridge that came with your pool filter. Make sure you purchase a filter that is of high quality and provides sufficient filtration for your pool size. Investing in good-quality pool filter cartridges will ensure your pool water stays clean, clear, and healthy all season long.
