Frequently Asked Questions
What are the dimensions of the PMA30-2002-R?
The PMA30-2002-R is 7 inches in outer diameter, 7.25 inches long, with an open top and an open bottom. Total filtration area is 30 square feet. Before ordering, pull your existing cartridge and measure it yourself, or check the label inside the housing. OD and length both have to match within about an eighth of an inch, and the end-cap style needs to match exactly so the cartridge seats properly when the lid closes.
What other part numbers are interchangeable with the PMA30-2002-R?
PMA30-2002-R is the same physical cartridge as C-7330, FC-1003. Same dimensions (7" × 7.25"), same open top, same open bottom. The Pleatco, Unicel, and Filbur boxes ship the same media inside, just with different stickers. The only thing to watch is the end-cap style: if a cross-reference has a slightly different cap design, it may not seat right in your housing.
How often should I replace the PMA30-2002-R?
Most filter cartridges last between 12 and 24 months. Pull the PMA30-2002-R every few months for a hose rinse, soak it in cleaner quarterly, and replace it when the pleats are torn, channeling, or won't come clean. Bather load, water chemistry, and how often you actually clean it all matter more than the calendar.
How do I clean the PMA30-2002-R?
The PMA30-2002-R has open ends on both top and bottom, so water flows straight through. Pull the cartridge from the housing and hose it down. Hit the pleats from above at about a 45-degree angle so water rinses debris out instead of packing it deeper, and work top to bottom while rotating the cartridge. Skip the pressure washer. The high pressure tears or collapses pleats, and once that happens you've lost media that doesn't come back. Every few months (or at every water change, whichever comes first), do a deep clean: overnight soak in a hot tub filter cleaner, then a thorough rinse. If your cartridge has a closed end cap, let it dry before reinstalling so you don't trap moisture inside the cartridge core.
Which hot tubs and spas use the PMA30-2002-R?
Pull your existing cartridge and read the part number off the end cap, or check the label inside the filter compartment. That's the most reliable way to confirm compatibility.

Fitment notes
The old-style Eco-Pur outer cylinder, open at both ends with 4-1/8 inch openings. Both sheets agree exactly on 7 by 7-1/4 inches and 30 sq ft. Unicel dates this cartridge to the 2002 to 2005 Eco-Pur filtration systems and notes that it works with an inner cartridge, which is the 8 sq ft PMA10. The PMA40-2003-R and PMA45-2004-R replaced it in later systems and are both wider, so check which generation your tub has before ordering.
