How to Measure

Confirm all three dimensions match your existing cartridge before ordering.

Length

13-5/16" — top endcap to bottom

Outer Diameter

4-15/16" — widest point across

Center Hole

2-1/8" — inside of the hole

What if it doesn't fit?

We back every order with an exact-fit guarantee. If it doesn't fit your filter housing, contact us within 30 days for a full refund or exchange — no hassle, no restocking fee. Call or text (732) 395-2225.

How long will these last?

With regular cleaning, expect 1–2 seasons of use. Rinse with a garden hose every 4–6 weeks, and do a deep soak in filter cleaner once or twice a season. Replace when you see collapsed pleats, tears in the media, or pressure stays high after a fresh clean.

How do I confirm this fits before I order?

Measure your existing cartridge in three spots: length end-to-end, outer diameter at the widest point, and the inner diameter of the center hole. If all three match the specs listed above, it's a direct fit.
