APC 100 Sq Ft Spa Filter Cartridge (APCC7440)
Drop-in replacement for Coast Spas and Waterway.
The APC APCC7440 is a 100 square foot pleated spa filter cartridge built to drop straight into Coast Spas top-load systems and Waterway Plastics 100 sq ft housings. It cross-references the Unicel C-5396, Pleatco PCST80, Filbur FC-2975, and OEM Waterway 817-0098, so if any of those numbers are on your old element, this one fits. You get 222 pleats of 3 oz Reemay polyester media and open 2-1/8 inch end caps, sized at 5 5/16 inch diameter by 21 5/16 inch tall.

Frequently Asked Questions
Will the APCC7440 fit my spa?
It fits Coast Spas top-load (in-line) 100 systems and Waterway Plastics 100 sq ft housings. The easiest check is the number printed on your current cartridge. If it reads C-5396, PCST80, FC-2975, or 817-0098, the APCC7440 is a direct replacement.
What are the exact dimensions?
The cartridge is 21 5/16 inch long with a 5 5/16 inch outer diameter. Both the top and bottom end caps are open with a 2-1/8 inch inner diameter, matching the original Coast Spas and Waterway element.
Is this the 100 square foot size?
Yes. The APCC7440 carries a full 100 square feet of pleated media across 222 pleats. That is the high-capacity element for these housings, so you get longer intervals between cleanings.
Can I rinse and reuse it?
Yes. The 3 oz Reemay polyester media is reusable. Rinse it with a hose between the pleats every few weeks, soak it in a cartridge cleaner periodically, and replace it once the pleats no longer come clean or the fabric starts to break down.
How often should I replace it?
With regular rinsing, a spa cartridge like this typically lasts 12 to 24 months depending on bather load and water chemistry. Replace it sooner if you see torn pleats, flattened media, or pressure that stays high right after cleaning.

Let customers speak for us
Great price and it was the exact fit for my TM26 Filter.
Easy to install it took 20-25 minutes and it was back up and running with no issues!
Work perfect
Same pump and motor I needed for my pool setup and would’ve been great if I didn’t have to tear apart the new one to install old part. Best price I found anywhere too.
Great company to work with!
Came in great condition my kid loves it, fit perfect hes 6 and got a medium.
Order received. Thank you
This is a well built spa light with excellent cables and excellent customer service. Highly recommend
New flow switch worked perfect. Much cheaper than other sites. Arrived on time.
Good price works great!
Extremely fair company. Cares about their customers and are willing to do what it take to make you feel satisfied!
Dog chewed pool robot cord end. Ordered this fix it. Delivery was a little slow and I think some instructions should have been included as should have been a tiny allen wrench needed to tighten the wires into the plug. I got it done but think most homeowners would have a problem doing it. Other than these issues, the plug works fine and was much cheaper than buying a whole new cord.
Had a minor issue with pricing of a separate part in my order, but the sales team was responsive and reasonable, and worked with me to come to a mutually agreeable solution. In a world where character and reason has become the exception rather than the norm, they stand by their word and were committed to finding a fair solution.
I highly recommend them, and will look to them first in the future when searching for pool and spa products. Thanks, Sal and team!
I really like it
The part fit perfectly. Shipping was quick. Would definitely purchas from PST Pool Supplies again in the future.
