Frequently Asked Questions
How does the PLM150 compare to the System:3 S7M120?
Both are Sta-Rite modular media filters with the same balanced flow concept and matte black finish. The PLM150 is significantly more compact — 27.75-inch height vs. 42-inch for the S7M120 — making it the right choice for above-ground installations or any tight space. The S7M120 has more filtration area (300 vs. 150 sq ft) and suits larger pools. The PLM150 ships in a much smaller box and weighs 43 lb vs. 135 lb for the S7M120.
Is this filter suitable for above-ground pools?
Yes — this is one of the few modular media filters specifically designed for both above-ground and in-ground pools. Its low profile and compact dimensions make it practical for above-ground installations where full-size filters are too tall or heavy.
How does modular media compare to sand filtration?
The PLM150's shallow-pleat modular media provides up to 15 times more dirt-holding capacity than a sand filter of equivalent size. This means dramatically less frequent cleaning, better water clarity, and longer filter cycles — all from a more compact unit.
