Feeling lost when it comes to measuring your spa filter? Don't worry, we're here to help simplify the task with our complete guide to measuring your filter.
If your current filter is marked with part number R173215, C-9410, or PT100, this cartridge is the direct replacement. It is also compatible with Pleatco PAP100 and PAP100-4, as well as the corresponding Magnum and Unicel models. If you're unsure, our filter selection guide can help you find the right model.
This cartridge measures 592 mm (23.31 in.) in length and 260 mm (10.24 in.) in diameter, with 101 mm (4 in.) open ends on both sides. Measure your current filter at these three points before ordering. Even a small difference can prevent proper installation. For step-by-step instructions, see our spa filter measurement guide.
This cartridge is sold individually. If your Pentair filter system requires multiple cartridges, simply adjust the quantity when placing your order. No multi-pack or paired version is available for this part number.
Regular cleaning extends the life of the cartridge and helps maintain optimal filtration performance. Specialized cleaners are available for large pool filter cartridges like this one. Browse our selection of spa filter cleaning products.
It's not recommended to wait until water quality noticeably deteriorates. A clogged filter puts extra strain on the pump and can affect your pool's water balance. The 2-year warranty covers manufacturing defects, but it does not cover normal wear caused by delaying cartridge replacement. Replace the cartridge based on how frequently your pool is used.
If the cartridge is in stock, orders placed before 1:00 PM are shipped the same day. This is especially important if your pool is out of service while waiting for a replacement filter. Please check product availability on the product page when placing your order.
Returns are accepted provided the cartridge remains in its original, unopened packaging. Before ordering, we recommend verifying both the dimensions and the compatible part numbers to avoid unnecessary returns. If you're unsure about compatibility, first compare your current filter's part number with the cross-reference numbers listed on the product page. Returns are accepted within 14 days of delivery. For professionals in the pool and spa industry, this return period may be extended to 60 days.
