APC APCC7673 150 Sq Ft Pool Filter Cartridge
Full-size filtration for the Posi-Clear PXC-150.
The APC APCC7673 is a 150 square foot replacement pool filter cartridge built as a direct drop-in for the Sta-Rite Posi-Clear PXC-150 and the Waterway Pro Clean 150 (2006 and prior). Measuring 8-15/16" in diameter by 28-3/16" tall with open 4-inch ends, it crosses to Unicel C-8416, Pleatco PWWPC150B, and Filbur FC-2576 so you can stop hunting part numbers and just reorder. You get 177 pleats of heavy-duty polyester media that pull dirt, leaves, and fine debris out of your water at the highest surface area in the Posi-Clear lineup.
Maximum Surface Area
At 150 square feet, the APCC7673 is the largest cartridge in the Posi-Clear PXC family, which means longer runs between cleanings and lower pressure on your pump. The 177-pleat design packs more filtering media into the same housing footprint, so water passes through slowly enough to trap fine debris while keeping flow strong. More media area also means each particle of dirt has more room to land, so your filter loads up evenly instead of clogging in one spot.
Built to Last a Season
The cartridge uses heavy-duty polyester media bonded to molded end caps with an integrated gasket, so it seats cleanly and seals without bypass. The reinforced center core resists collapse under flow and during high-pressure rinsing, and the pleats spring back after each cleaning instead of matting down. Rinse it, let it dry, and reinstall it season after season until the media finally wears out, exactly the way a quality replacement cartridge should behave.
A True Drop-In Fit
This is not a close-enough substitute. The APCC7673 matches the Sta-Rite 25230-0150S original dimensions exactly: 8-15/16" diameter, 28-3/16" length, open 4" ends top and bottom. Drop it into your Posi-Clear PXC-150 tank, line up the molded gaskets, close the clamp band, and you are done. No shims, no adapters, no trimming. If your old cartridge fit, this one fits, and it crosses to every major brand so future reorders are easy.
Who It's For
Inground Pools
Sized for full-size inground pool filtration on the Sta-Rite Posi-Clear PXC-150, where 150 square feet handles larger water volumes with fewer cleanings.
Waterway Pro Clean 150
A direct fit for the Waterway Pro Clean 150 systems built in 2006 and prior, using the same open-end cartridge body.
High-Demand Setups
Pools with heavy bather loads, nearby trees, or long pump run times benefit from the extra media area, which stretches the time between rinses.
Reorder & Replace
Anyone replacing a worn Unicel C-8416, Pleatco PWWPC150B, or Filbur FC-2576 can swap to the APCC7673 with no change to fit or performance.

Frequently Asked Questions
What filter does the APCC7673 fit?
It is a direct replacement cartridge for the Sta-Rite Posi-Clear PXC-150 and the Waterway Pro Clean 150 built in 2006 and prior. Both use the same 150 square foot, open-end cartridge body.
Does this replace Unicel C-8416, Pleatco PWWPC150B, or Filbur FC-2576?
Yes. The APCC7673 is dimensionally identical to all three and to the OEM Sta-Rite 25230-0150S. If your current cartridge is any of those, this drops in with no change to fit or flow.
What size pool is a 150 sq ft cartridge meant for?
It is the full-size option in the Posi-Clear PXC line, intended for inground pools where the larger 150 square foot media area handles higher water volumes and stretches the time between cleanings. The right size for your pool follows your existing filter, if your tank came with a PXC-150 cartridge, this is the match.
How are the exact dimensions measured?
The cartridge measures 8-15/16 inches in outer diameter and 28-3/16 inches in overall length, with open 4-inch inside-diameter ends on both the top and bottom. Those numbers mirror the original Sta-Rite part.
How often should I clean it, and can it be reused?
Rinse the cartridge when the filter pressure gauge rises about 8 to 10 PSI above the clean starting pressure. Hose it off, let it dry, and reinstall it. The pleats recover after cleaning, so a single cartridge lasts multiple cleanings until the media finally wears out.
Can I install this myself?
Yes. Power off the pump, release the pressure, open the clamp band on the filter tank, lift out the old cartridge, drop the APCC7673 in over the standpipe, and reassemble. It is a tool-free swap that takes only a few minutes, no adapters or trimming required.

Let customers speak for us
Loved how fast it got here. It has small wiring and I was glad it was in a protective envelope and it arrived without breaking.
just as listed. well packeged, fast ahip, works fine. purchased to remedy issue with heater and ozone injectorboth operating together. might have been able to just bend old switch a bit but did not try that.
Great customer service and knowledge of product. Asked of compatibility and they had the answer. My intouch2 was not working so I researched new intouch3 from Spa Dealer and they wanted $75 just to come out, then $125 for up to an hr...just to confirm what I already knew. Contacted PST and they had the product and confirmed compatibility. Saved me some $$.Thanks PST.
